There is certain information that you may require so you could make a wise decision and before you sign the check on buying a host of item.

Factors

Screen: Generally, the more screen surface area you apply means more volume of drilling fluids you can clean.GN provides two panels, three panels and four panels for processing different volume of drilling fluids. In addition to the surface area, the API standard of screens is measured by the amount of holes per square inch on the panel screen. Different API number of shaker screen controls the size of cuttings that you remove. Sizes will change replying on the size of the cuttings and the type of formations you are removing

Shakers: There are three kinds of shakers in the market including orbital, elliptical and linear motion. GN provides the most reliable linear motion shale shaker. Technically, linear vibration is generated by a pair of eccentric motor turning in opposite directions. The design is able to allow for the development of straight line or linear motion that can also be produced in a positive incline. Therefore, linear shaker is capable of processing heavy clays, debris, small particles and ultra-fines. 3C (1)

Hydrocyclones: In order to further effectively remove ultra-fine solids the hydrocyclone size may either be 4, 5, 10 or 12 in. The smaller cone you have the ultra-fine solids you will clean. Each size cone has the corresponding micron cut point. GN 4 inch cones have a micron cut of 20 microns and the 10 in. have a 40 micron cut. Each 4 inch Hydrocyclone cones process the drilling fluids at a rate of 50 gallon/minute. Each 10 inch Hydrocyclone cones process the drilling fluids at a rate of 500 gallon/minute.

Mud Recycling System for HDD Rigs

Leave a reply

Generally, trenched will be excavated for pipe laying or conduits and cables installing. While, in some case that trenching is not practical for geographic factors or environmental reasons, directional boring, usually known as horizontal directional drilling(shortened as HDD) will be applied. HDD is a typical example of trenchless technology which means using a surface-launched Drilling Waste Management to bore a path for installing infrastructure such as pipelines, gas lines, oil line, sewer lines, water lines, power cable conduits, and telecommunication. HDD is normally applied when a river, road, landscape, or a congested place needs to cross for pipe and cable laying. Until now, installation length by HDD has been up to 2000 meters, and diameters up to 1200 mm have been finished in short length. Yet, that does not necessarily mean that HDD can be adopted for all road-cross or river -cross drilling. Actually, solids rock or sedimentary rock is the most suitable material. HDD is used instead of other techniques mainly for the following benefits. HDD not only makes traffic disruption less and deeper or longer installation possible, but ensures a lower cost and environmentally safer.

GN Solid America is specialized in design and build up mud recycling system for HDD rigs, and for a decade’s innovating and evolving, GN’s mud system is widely used in Australia, India, and other countries for HDD rigs.

Primary Safe Unit for Drilling Fluids-Mud Gas Separator

Leave a reply

We could see the mud gas separating installed in many drilling rig jobsite. Regarding to complicated geologic environment of drilling site, mud gas separator is used for separating the hazardous gas from the drilling fluids. Mud gas separator not only is used for oil & gas drilling site, but also it is applied for the deep mining drilling jobsite.

How is GN mud gas separator working?

The drilling fluids/mud from down hole goes into mud gas separator (poor boy degasser).Due to the gravity force, the mud drops down on the 1000mm diameter vessel of poor boy degasser. Mud collides on buffer plate of pipe so the dangerous gas will be relieved from the drilling fluids. Obviously, gas flows to the top of 8 inch vent line which is connected with the flare igniter to burn out. Normally, flare ignition device is about 160 ft away from the poor boy degasser to assure the safe distance burning. Meanwhile, the mud would go down and accumulated at the bottom of mud gas separator, and subsequently flow to the into the solids control system including shale shaker, desander, desilter and decanter centrifuge etc

Why we choose GN mud gas separator?

1.GN is recognized world-wide for accuracy, durability, from easy to complex and standard to customize in order to design and manufacture the most reliable mud gas separator .

2. GN design, application, and manufacturing engineers have designed custom products to fit every single application. Such as, we could horizontally fold the mud gas separator on the skid for easy transportation.

Today, GN shale shakers are not only used in the oil & gas drilling project but also largely applied for the HDD (Horizontal Directional Drilling), water well drilling and dredge slurry system etc.

GN a variety model of shale shaker applied for different purpose of drilling project.

1. Normally, GN double deck shale shaker or two-panel shale shaker are mainly used for the HDD, water well drilling and TBM drilling. First of all, dual shaker and two-panel shaker have the compact design and small footprint matching with small treating capacity and dual function requirement.

2. GN 3-panel and 4-panel shale shakers are largely used for the oil & gas drilling and dredge slurry application. Large treating capacity and fast replacement shaker screens are main advantages.

GN 3- panel shale shaker VS Derrick FLC503 model shale shaker.

The main difference between GN shale shaker and derrick shale shaker is the shaker screen. GN uses pretensioned shaker screen as the similar as MI-Swaco shaker screen. Derrick choose their own patent pyramid shaker screen or the new hyperpool shaker screen

For the rest of technical configuration, GN shale shaker is really similar to derrick shale shaker such as
1. Both G force of shale shaker is under 7.5G.

2. GN 703E-HB weir feeder is 895mm and derrick is with 650mm

3. GN shale shaker 703 treating capacity is 530 GPM under API 40 shaker screen, Derrick flc503 shale shaker is 560 GPM of a 17.8 PPG fluid

4. GN Screen area is 2. 63㎡ and Derrick screen area is 24.9 square foot (2.3㎡)

In Summary, there is not much difference between GN Shale shaker and Derrick shale shaker. GN Solids America also supplies desander, desilter, mud cleaner, decanter centrifuge, vertical cutting dryer and centrifugal pump etc.

Suck Dangerous Gas from Fluids-Vacuum Degasser

Leave a reply

GN Vacuum degasser is a special equipment for purifying drilling fluid. Vacuum degasser plays an important role in drilling fluid viscosity and stability of drilling fluids density. Even the drilling fluids does not contain harmful gases, it could work as a big mud agitator

Vacuum Degasser Working Principle:

Firstly, the vacuum pump suction is generated in the negative pressure zone sealed container, under negative pressure, the fluids will be sucked by the tube into the hollow shaft of the rotor, By the collision between drilling fluids and units, the dangerous gas within fluids will be pump to be discharged into the safety zone . the fluids will flow back to the mud tank. Therefore, the vacuum is able to complete separate the harmful gas and recovery the drilling fluids.

The feature of vacuum degasser

1 uses negative pressure degasser, reasonable design structure of science, to achieve effective gas-liquid separation, filter out impurities, ensure the exhaust pipe is always smooth;

2 using a belt drive, avoiding the complicated gear mechanism to ensure long working hours;
