The High G shale shaker is a linear vibrating screen, which is used to minimize the absorbed liquid phase of the drilling cuttings discharged from the main vibrating screen and the hydrocyclone, and return the treated liquid phase to the circulation system. The drying screen shall be used in closed-circuit circulation system or in places where it is required to reduce the liquid phase content of drilling wastes. There are chemical and mechanical methods to reduce the liquid phase discharge. The chemical method is to use the dehydration reaction system and the mechanical method is to use the linear vibrating screen. The two methods can be used alone or in combination. The dry vibrating screen is used to dehydrate the drill cuttings separated from other solid-phase separation equipment. These drill cuttings are usually discharged from the main vibrating screen or the hydrocyclone in the drilling fluid circulation system. The dryer recovers and processes the liquid phase in these drill cuttings. Since flocculation, coalescence and other action units are usually used in the dehydration system, the recovered liquid phase contains colloidal particles, Therefore, the influence of these colloidal particles on the performance of cobalt well fluid must be considered.

GN high G shale shaker was designed for drilling waste treatment, which used 4panels shaker screen, the G force can reach 8.5 Gravity. GN high G shale shaker has the good ability to recycling the mud from the drill cutting. It convenient for client to reduce the cost of drill cutting treatment, and the recycled mud also down the cost for drilling mud. This High G shaker used Italy brand vibrator, and the whole machine body is reinforce design, that guarantee the long lifetime.
Our high G shale shaker had sold to more than 20 countries, and get the good feedback from customer. The G force is adjustable, which means client can down the G force and used it as normal shaker. If your project have demanded on this equipment, welcome to contact us.

As we all know the drilling mud is very important for petroleum well drilling. As usual, the petroleum well depth can arrive to 1000 to 7000 meters. In this program, the rig can meet lots complex geology situation, we must use drilling mud to help rig to protect well. For example , at the rock stratum, rig need lubrcate and take out the drill mud out well. Drilling mud is most widely be used for this application. Drilling mud is very important medium material to guarantee the drilling success.

Drilling mud can balance the pressure of outside and inside well. Through adjust the mud density by mixing barite or some other material to get the adapt density that we need. These high density mud can stop the well wall extruding rig, and prevent the headframe landslide. So the correct density is the key to guarantee the mud property. However in the drilling progress, as long as the mud be recycling and using time by time, the mud property will reduce and also it it mill mix some air contented inside of mud. Some times, we can see the mud have bubble. These bubbly will reduce the mud density and bring disaster since it can lead the blowout. Remove out the air is very important for drill.
GN vacuum degasser is specially used to remove these bubble. Inside the desander tank, it will generate a vacuum space to suck the mud into its tank, meanwhile ,the mud will be blend with high rotation speed, the center of liquid will generate a hydrocyclone , the air pressure at this part is very low, the air will be push out from high pressure place the inside of mud. And reach our purpose that remove out the air. GN degasser is a high efficiency equipment for drilling mud process, if you have demanded , welcome to contact us.

Last week, GN delivered 2 units 18inch decanter centrifuge to abroad client for waste water treatment. As we all know GN begin with manufacturing solids control equipment for oil gas industry. Such as shale shaker and vertical cutting dryer. As long as the accumulation of technology, we upgrade our centrifuge and designed the centrifuge for waste water treatment. Actually this is our fifth generation centrifuge. Compared with old design, it adapt new technology and upgrade the control system.
In this project , it is GNLW454ET-VFD centrifuge. The bowl length is 4 times of bowl diameter. The old design is 3 times length. Longer bowl means the material can stay longer time for treatment, we can get dryer solids and more clean liquid. The 2 units centrifuge are for municipal water treatment. The solids content is about 2%, and the actually treating capacity is about 40 cube meter. The actual treating capacity related with solids content. When solids content is higher , the capacity is lower. For this centrifuge, we mounted 1 unit 45 kw motor and 1 unit 15kw back motor, both are controlled by VFD. The speed is adjustable, the max GN force i2 2093G.

To longer the life time, we mounted tungsten carbon tile to protect the scroll. As we all know the scroll is easily wearing when it push solids. This tungsten carbon tile is anti-wear and protect scroll. When some of these tiles was damaged, client only need to replace the damage part.
To protect the equipment well, we add some monitor on centrifuge, such as temperature monitor and vibration monitor. These measured sign can transfer to PLC to control the equipment. When equipment is abnormal ,the control system can stop the machine automatically.

GN can provide lots customized function according to client requirement, control the feeding flow, adjust speed automatically. We are professional centrifuge manufacture . and also solids-liquid separation system. If you have demand, welcome to contact us. We will be pleased to support.

It has been 3 years since the pandemic outbreak. which take lots issue to our work and life. Even the OTC offshore technology conference had to be canceled for 2 years. People can not be Houston to particle in OTC. and also consider the pandemic is controlled gradually ,it will be restarted on May 2,2022. GN also will particle this OTC with exhibitor. We expected to meet with our old customer on this OTC showing, and introduce our equipment to new client.

As we all know OTC will attract the oil gas client from all over the world . it is the biggest conference in oil gas industry. GN almost participated in OTC of every year, and it is a good opportunity for company to show their new equipment and new technology. GN solids America is near with OTC exhibition, and our Houston colleague will participate in the OTC. In this time, we shipped shale shaker , vacuum pump and shaker screen for display. All these 2 equipment are most featured of GN products. However, we also take the introduction of other equipment , such as Decanter centrifuge and vertical cutting dryer. GN is not only the equipment supplier and also the whole solution supplier. we are good at provide customized proposal for client to provide all kind system for mud treatment.

OTC is the first show of GN since pandemic time. We had almost 2years no meeting with client, and we are very expected to meet with customer.After OTC , GN also plan to join more exhibition in different countryside . We are gradually return normal work of before pandemic. When we setup our booth, we also saw lots our customers’s booth. I believe this OTC will attract lots people be here for new technology communication. GN is always open to welcome every to be our booth or our Houston to know more about our company and product.

In mining industry ,there are lots slurry need to separate out the solids and liquid. For some mining explosion drilling always used the diamond core drilling , which is to get the geological condition and Explore mineral reserves. This kind diamond core drilling ,which also generate less slurry need to treatment. and most times, this kind drilling need to change job site frequently. How to treat these drilling mud is a big issue for drilling team. They need to recycle the water since the wild working is hard to get water resource, and they also need to small size device to convenient the translation, and high work efficiency to separate out the solids and liquid. To solve this problem , GN technology team developed GNLW223 mining Decanter centrifuge.
Decanter centrifuge is one of the best device for solids-liquid separation. It utilize the separated force generated thorough high rotating speed. And the different density material will be sepa

rated on different layers. And finish the solids liquid separation. This Decanter centrifuge is only 9 inch diameter for centrifuge bowl, which is mini device. It is very convenient to transport it to different job site. The treatment capacity is about 2 cube meter per hour, this is enough for most of diamond core drilling project.

This mini centrifuge is very popular in diamond core drilling project, we sold it to Canada more thanks 40 units every year , and the market is keep raising. Many client of Latin America send inquiry for this equipment. This centrifuge can be controlled by VFD to running with fixed speed. It depends on client requirement. Some of our client only purchase the main body of centrifuge, and then they assembly the whole machine by themselves. GN can provide different proposal according to your requirement, if you have demanded, welcome to contact us to get more info.

Different from the application in oil and gas drilling, the application of shale shaker is developing fastest in the field of excavation free drilling. Many of the above types of vibrating screens, together with hydrocyclones, constitute drilling fluid cleaning equipment. Micro tunnel micro tunnel engineering is widely used in Europe and more and more in the United States. Micro tunnel drilling is a kind of horizontal drilling in a large borehole (from 27 to 10F), with cobalt entering while laying pipelines. This method is most typical when laying or replacing water pipes and sewage pipes under urban buildings and traffic arteries.
In order to prepare for construction, dig out large-diameter vertical boreholes or open caissons first, so as to install drilling equipment and hydraulic press at a fixed depth. The position of the open caisson is slightly lower than the equipment level, so a sedimentation tank can be formed when the drilling fluid returns, which is conducive to the removal of solid phase. The drilling fluid pumped back to the surface is pumped into a simple solid phase removal system through a submersible pump, which is mainly composed of a vibrating screen and a drilling fluid cleaner installed on a small storage tank.

River crossing in order to lay pipelines at the bottom of the river, it is necessary to drill a small-size well on the riverbed. When reaming with a larger diameter hole where the pipeline is laid, the pipeline is connected to the drilling tool and dragged back under the river. When laying large-scale pipelines, a solid solid control system must be established with composite vibrating screen, desander, desilter and centrifuge. Drilling fluid cleaning equipment reduces the waste of drilling fluid.
When laying pipelines and cables across roads, it is often required to pass under the roads. The roadside drilling shall not affect the traffic or damage the road surface. Usually, the drilling size is very small to avoid the use of solid removal equipment. If the drilling fluid is affected by the accumulation, the drilling size is too large or the subgrade is wide, the vibrating screen or drilling fluid cleaner will be used.
The laying of fiber optic cable does not need to drill a large borehole. However, due to the frequent construction in residential and commercial areas, the drilling fluid and drilling solid phase must be loaded into special devices. At this time, the solid control system only includes a small storage tank, a pump box and a small vibrating screen.

Tank cleaning is a big market in global. Almost all industry has this demand to clean tank, what ever crude oil tank, water tank, oil tank or mud tank. In tank cleaning process, the settled sludge on tank bottom is always the biggest problem for operator to clean up. The normal pump is useless to move them out tank because these settled waste always is high solids content. It takes a lot of labor with low work efficiency. Aim to solve this problem, GN designed the mini vacuum pump based on his stand model. Last week we delivered this mini pump and mini Decanter centrifuge to our client.

This mini vacuum pump is movable with small size. Its capacity only 5 m3/hour. This capacity was designed for normal mud tank or ship cabin. Convent to move and enough to pump out all waste in short time. Same with GN standard vacuum pump, it is driven by high pressure, no electric spark, so this pump can be used anywhere that has high strictly requirement to explosion proof. The pump can transfer solids size smaller than 5cm, even the totally dry solid. However, the pump is best at pumping sludge with liquidity.

GN mini Decanter centrifuge is 9 inch centrifuge bowl,which capacity is 130L/min. Aim at small treating capacity of solids-liquid separation. Especially the outdoor application, easy to transport and convenient to place. For this client we also shipped this mini centrifuge to treat these tank sludge. Recycle the water for reusing and dryer solids. This mini centrifuge is most featured equipment of GN. It almost the smallest centrifuge of the world. Currently ,our client use it for mining slurry treatment, beverage, tank cleaning ,manual separation. People is trying to use it for different industry.
GN is good at providing customized solution for client special project. We have the whole series equipment for different solids content treatment. If you are interested in our equipment, welcome to contact us.

Most offshore drilling equipment has more strict requirement to equipment quality, no matter the rig machine or solids control equipment. The manufacture need to make them with higher grade standard. As usually API standard was acceptable by most countries of the world. Offshore drilling equipment require most times will require DNV lifting , higher explosion proof standard and also the anti corrosive coating since the ocean environment has high corrosive to equipment. GN solids control has more than 15 years .We exported to more than 75 countries and provide equipment to many top oil gas industry in the global, and built long term cooperate relationship with them.

Last week we delivered several sets cutting drying high G shale shaker to offshore drilling platform. These shaker are specially designed for offshore drilling waste management application. This high G shaker was used to treat drilling cutting. The vibration G force can more than 8 G, and the normal shaker is 7.5 G. This shaker can recycle partial drilling mud from drilling cutting and dryer cutting to convenient transporation. It is helpful to reduce transport cost and for the further process. As we all know drilling mud is high solution ,even the drying drilling cutting to be treatment by profession device to reduce pollution.

From the photos we can see, this high G shaker equipped a vacuum device to generate a negative pressure to suck the liquid from solids cutting and recovery them. This design makes our high G shaker very popular in the market, and client use them to recycle drilling mud. BTW, we also designed the anti splash device to cover the shaker to meet the offshore platform requirement about clean. All these was designed by GN own.
GN can provide a entire series solids control equipment and wast management equipment for drilling industry. We are good at customized build system according to client requirement. Such as mud system, drilling cutting treatment system. If your project have demanded on these equipment, welcome to contact us.

The drilling well site must be equipped with at least one vibrating screen. The purpose of shale shaker and other solid removal equipment is the same, which is to reduce the drilling cost. Drilling fluid always require the particle size and content in drilling fluid. Shale shaker can remove out the big size solids contend in the drilling fluids backed from well. If there solids can not be removed timely, which may cause lots problems in drilling.

Consider whether to use a coarse mesh screen. When a large amount of drilling cuttings or clay returns to the wellhead, it is necessary to use a coarse mesh screen. Generally speaking, when the drilling fluid flow rate exceeds 1000gal / min in a 17 in diameter open hole, it is required to use a coarse mesh screen before using a fine mesh shale shaker. Finally, the number and type of main shale shakers used to treat all drilling fluids should be selected. The selection goal is to let the non weighted drilling fluid pass through the most detailed screen cloth as much as possible. For weighted drilling fluid, the use goal of shale shaker is to make all drilling fluid pass through API 200 mesh screen cloth (too fine screen cloth will remove more weighting agent).

The selection of screen cloth. it is said that some professional software can be used to select the mesh number of vibrating screen cloth. However, the data used in these software are basically obtained from the cobalt well fluid prepared in the laboratory, so they have some limitations. Any drilling fluid treatment agent formula may reduce the treatment capacity of the shale shaker system. For example, cobalt well fluid containing starch is difficult to screen, because starch, as a good filtrate reducer, tends to “paste” the fine screen holes. The drilling fluid with high static shear force is also difficult to pass through the fine screen. Therefore, the vibrating screen cloth that should be used to deal with a certain fluid flow rate is not introduced here. The selection of screen cloth for various drilling fluid shale shakers is mainly determined by repeated test method. It is best to contact the manufacturer and ask for suggestions on the selection of screen cloth in this area.

Shale shaker is a conventional equipment used to separate solid phase from circulating drilling fluid. There are many shapes and types of shale shakers. Commonly used are
cobalt well fluid flows along the center on a square or rectangular screen cloth.
drilling fluid flows along the center on a rotating, non vibrating cylindrical screen cloth
drilling fluid flows from the center to all around on a circular screen cloth.

Although vibrating screens of other shapes have been in trial use, they have not been commercialized. Most vibrating screens adopt rectangular screen cloth. Large solid particles are removed at the bottom of the vibration. Small solid particles and drilling fluid flow through the screen surface and re-enter the circulation system. The solid in the drilling fluid greater than 74um is unfavorable to the performance of the drilling fluid. Api200 mesh (74um) vibrating screen is formulated on this basis. Only 3% of the weighting materials that meet the API classification standards have a particle size greater than 74um. The screen mesh is larger than 74um. Under this size, most barite will be removed from the drilling fluid, which will seriously affect the performance of the drilling fluid and the drilling cost. Vibrating screen is the most important and earliest equipment used for solid phase removal, which plays a very important role in solid control system. It is the first line of defense after the drilling fluid returns to the surface from the wellbore, which generally has a great impact on the cost. However, if the damaged screen cloth is used, the cobalt well fluid does not pass through the screen cloth, and the mesh number of the screen cloth is improperly selected or partially damaged, the next solid control system will not operate normally. Shale shaker is suitable for any type of drilling fluid. The selection of screen cloth is determined by circulation speed, shale shaker structure, borehole properties, drilling fluid performance and other factors. Many properties of drilling fluid show the processing capacity of screen cloth.

GN solids control has been in shale shaker manufacture for more than 15 years, we can provide different type shaker according to client requirement. If you have demanded , welcome to contact us.
