Structure and Applications of GN Desander for Oil and Gas Drilling

The desander would be the two-level solids handle gear used for drilling fluids treatment. As one particular in the indispensable and crucial devices for stabilizing and regulating those technical indicators with the drilling fluids, the drilling mud desander has also been extensively applied inside the purification in the drilling fluids.
Desander would be the second step in separation gear for treating drilling liquid. It separates solids and liquid treated after shale shakers, recycles the barite of weighted drilling and removes the surplus cuttings that happen to be larger barite particles. As the mixture of your hydrocyclone desander plus the vibrating screen, the drilling mud desander would be the three-level solids handle gear made use of in the solids control program on the drilling fluids. It truly is primarily created up of the vibrating screen, the distribution manifold at the same time as the hydrocyclones. The drilling mud desander is primarily employed to remove the damaging strong phase using the granularity of more than 45μm so as to make sure the fantastic properties with the drilling fluids.
The desander is mostly and broadly applied within the petroleum business, the oil and gas drilling, the exploration sector, the trench-less engineering, the geotechnical engineering, mining, metallurgy, coal as well because the hydroelectric business.
Structure of GN Desander
The desander system is created up of the screening system, the adjusting and supporting method, the aqueduct, the foundation, the pressure gauge at the same time as the desander hydrocyclones.
The desander is made around the basis of particle setting principle. The separated medium-drilling liquid enters along the inner wall of clone spirally, depending on the stress and speed created by centrifugal pump. Beneath the function of centrifugal force and gravity, the larger particles are sunk along the inner wall of clone spirally and drained from bottom outlet to be separated in shale shaker with smaller sized mesh. Other mediums are ascending along clone spirally to enter the second separation device from overflow outlet for additional purification.
Functions & Benefits of GN Desander

You might possibly have heard desilter 5-stage solids control plan. Possessing said that, what is specifically the desilter 5-stage solids deal with system? Proper here, Guanneng Business can clarify this for you.
Initial Stage of Solids Manage Strategy
desilter is broadly usually known as a solids handle equipments applied in drilling projects. It is a fairly basic gear that could separate the drilling cutting more than fundamentally, the solids manage and purification come about within the related time. Just as its name implies, solids manage is separate the solids within the fluids, even though the drilling cutting in conjunction with other large size impurities becoming separated, the drilling mud is purified.
Second Stage of Solids Control Strategy
A vacuum degasser might be utilised as the second stage purification gear. Within this stage, there’s no solids separated inside the drilling mud, just the invasive air is removed. Why do we’ve to take away the air in the drilling mud? Invaded air can lessen the particular gravity in the mud and make the centrifugal pump work with low efficiency.
Third Stage of Solids Handle Approach,the releated pls refer to http://mudcleaner.wordpress.com/2014/05/04/gn-desilter-procedure-method/
Quickly just after becoming treated by vacuum degasser, drilling mud is fed into desander by centrifugal pump. The principle parts of a desander will likely be the hydrocyclones. desilter can take away the sturdy Control System
Determined by the exact same functioning Handle Method
You are going to see this desilter equipment in significant mud program for oil & gas drilling. Decanting centrifuge is the leading role in this stage.

Accurate produced-gas measurement although drilling

Engineered to measure the volume of gas developed though drilling, the GN gas-flow meter measurement method is actually a step-change innovation assisting operators decrease the atmosphere influence of their operations, including the carbon footprint. Also to measuring flow although drilling, the gas-flow meter is usually utilised for reservoir characterization by detecting and monitoring nuisance gas through tight-gas/shale gas, underbalanced-drilling, or managed stress drilling operations. The gas-flow meter is suitable offshore or onshore and is particularly effective in shale gas plays. The ability to explore the application of GN gas meter gas is very powerful, already have their own patents.

Real-time flow measurement and composition analysis

The gas-flow meter installs directly into the flare line to supply real-time accurate gas flow measurement and composition analysis. It has no moving parts, requires small or no upkeep and requires no personnel to operate when it really is installed. The gas-flow meter operates using a higher degree of accuracy in dirty or wet situations, and it will not protrude into the flare line or obstruct it in any way.

Detection capability for modest gas quantities

Standard desander designed for drilling operations lack the accuracy or reliability to detect modest quantities of gas, especially detrimental when drilling tight-gas formations. The gas-flowmeter offers the capability to accurately detect and quantify even the smallest gas flows down to 0.1 ft/sec.

Extremely accurate measurement technologies

Very precise ultrasonic gas-flow measurement technologies, combined having a precision stress and temperature sensing transducer, measure gas-flow velocity, temperature and stress to determine actual and regular volumetric flow, as well as mass flow rates. Data sent for the Drilling Rig Data Acquisition System enables direct communications with any capture device such as a data logger program, laptop, or hardwired or wireless memory stick.

Decrease environmental influence and reduce expenses

The gas-flow meter helps lower charges by quantifying the true production possible of formations whilst drilling underbalanced. Real-time reservoir information improves the decision-making course of action and potentially reduces overall exploration and improvement expenses. The gas-flow meter makes it possible for operators to superior quantify and lower their all round environmental effect and carbon footprint. There are more on the GN’s official website describes the data and methods of measurement of gas flow meters, and look forward to your attention.

Gn PRO Shale Shaker

Explore everywhere，The brand new generation shale shaker combines balanced and gressive elliptical motion, enabling operators to change motion “quickly” as drilling conditions change. Having a simple switch of the switch, the shale shaker changes in the balanced elliptical to the gressive elliptical motion with no need to suspend or shut lower procedures.

Operators can alter the kind of motion needed either to handle high volume orduce dryer clippings, as drilling conditions dictate. Using the shale shaker, nonproductive time lost to altering out shakers to satisfy drilling conditions is no more an problem.

Balanced elliptical motion handles high volume solids

Effective to find the best-hole sections with heavy, high volume solids, the balanced elliptical motion vides 7.5 Gs of pressure to rapidly move high volumes of solids over the screens. The motion increases conveyance rates and shaker fluid capacity while enabling the shaker to cess heavier solids.

Progressive elliptical duces dryer clippings

The gentler action of the gressive elliptical motion works well once the clippings volume is reduced, such as with lower sections, and operators desire a longer drying out here we are at the clippings. The G-pressure is reduced to six.5 Gs to optimize drilling fluid recovery and duce dryer clippings. The efficiency of the motion enables for greater processing rates while growing clippings dryness to reduce haul off costs.

Composite screens vide longer existence and greater screen area

The mud agitator is made to use the gn america high-capacity composite screens that vide a substantial rise in fluid capacity in addition to excellent potential to deal with blinding viding dryer solids discharge along with a bigger internet functional screen area.

Multiple shakers mix to multiply results

As much as four shale shakers could be pre-aligned in the factory and mounted on one skid to permit simpler rig moves, needing just one lift. Dual and trip models may use a typical possum belly and can include integral feeder slide gates to balance flow or divert it one shaker.

GN USA company’s solids control equipment

USA Solids Control system of GN america company is for on-site treatment and removal of waste water-based mud slurry ultrafine solid development of skid-mounted physico-chemical treatment systems. 10 µg of mechanical separation of slurry separation of solid particles is very difficult, especially for about 2 μg of colloidal particles (low specific gravity solid-phase) can do about it. Whether on land or at sea, in waste management operations, treatment of waste mud face two issues: one is to reduce the volume of waste and subsequent processing costs, the other a recovery based liquid to achieve recycling. USA Solids Control system is necessary. Chemical treatment methods can make solid-free (clarification) water recovery from failure of drilling fluids, isolate and low rate of liquid-solid phase for further processing, these solid-state weight and volume than the original expiration of the mud becomes negligible, transfer and further processing costs are also much lower. In environmentally sensitive and water-poor regions in drilling operations, use of slurry dewatering system will bring about many benefits, and regulatory and economic considerations are almost essential.

The solids Control system for colloids or close to the colloidal particles, and factors that contributed to the solid phase precipitation is far from overcoming fluid relative to its suspension. Chemical treatment methods can change characteristics of mud, so that most of the suspended particles can be separated by mechanical methods. Centrifuge feed stream of appropriate chemical (flocculation and other reagents) enables colloidal particles aggregation formation of floccules, resulting in slow precipitation under the action of gravity or centrifugal force. This principle has been widely applied in sewage treatment and other practice, but the nature of the solid-liquid system of mud and sewage are very different and, therefore, chemical reagents selection and isolation of structures are very different.

Drilling fluid solids control system is an important part of modern drilling. Drilling fluid solids control system is to ensure that the normal circulation of drilling mud in the process of drilling and stable performance of the important equipment, drilling fluid solids control The solid control system The solid control system System is mainly composed of mud tank, vibrating screen, vacuum degasser, desanding cleaner, silt cleaner, mixer, centrifuger, the funnel of mud gun, mixed, the sand pump, mud agitator, increase the pump, shear pumps, etc. All levels of solids control equipment. Production, workover, drilling mud solid control system. Especially the workover rig with solid control system, developed by crown to solid control, substantial and durable, unique anti-corrosion technology, very suitable for workover treatment of actual production.

Decanter Centrifuge Differential Speed Calculation

Leave a reply

The differential speed for decanter centrifuge used in drilling waste management depends on the feeding slurry conditions.

1) What is decanter centrifuge differential Speed?

The bowl and the screw conveyor inside the bowl runs at the same direction, but slower than centrifuge bowl speed. That’s the reason why the screw conveyor will push solids out of the decanter centrifuge. The differential speed is the how much RPM the screw conveyor slower than the bowl speed. For oil gas industry, normally the operator runs the decanter centrifuge with differential speed from 10- 50 RPM. The more RPM differential speed, the faster the screw push the solids, so the more capacity the centrifuge can handle, but the more moisture solids will be discharged, and vice versa. The formula is as below.

Decanter Centrifuge Speed

2) How to calculate decanter centrifuge differential Speed

Differential Speed= ( Bowl Speed – Gearbox Input speed) / Gearbox ration

Gearbox Input speed means the gearbox pulley speed.

Gearbox ration= 57 for GNLW363 Series.

Gearbox Input speed is the back drive motor speed transferred from the belt to the gearbox depends on the pulley on the gearbox side and back drive motor side.

So for example, if the decanter centrifuge bowl speed =3200RPM and Gearbox input speed=1468RPM, then we can calculate

Differential speed=(3200-1468)/57=30RPM.

(2)Now operator wants to separate high gravity solids in the drilling waste so, he can adjust the decanter centrifuge bowl speed to be 2500RPM and ,if they do not adjust the back drive motor speed, the Differential speed=(2500-1468)/57= 18RPM

And if in this case, the operator wants to increase the capacity of the decanter centrifuge ,he can lower down the back drive motor speed from 60HZ to 30 HZ so gearbox input speed will change from 1468to 734RPM and decanter centrifuge differential speed=(2500-734)/57= 30RPM

Normally the customer can set 30RPM differential speed to check the performance and adjust the back drive motor speed to get the suitable differential speed for different mud.
