As a developing trend, the future mud system should be more and more different with past.

Past mud recovery system for drilling site

Standard mud system for drilling rig in the past is 4 steps solids separation.

Step 1: shale shaker

Step 2: desander

Step 3: desilter

step 4: decantering centrifuge

Advanced mud system for drilling rig

As the difficult for desander/desitler cone maintenance, more and more drilling site prefer not to match it. As a instead, they choose fine shaker screen for shale shaker to separate fine solids from the mud. In mean mainly 2 separation machine will be used for the mud system.

Advanced shale shaker with fine shaker screen to separate most fine solids.

Centrifigue will be used to further separate the very fine solids from mud.

Top mud systme manufacturer in China:

GN Solids Control is the only 1 API certified solids control and waste management manufactuere in China. Is owns distinct advantages for internaitonal market and different drilling mud systems.

 

Decanter centrifuge application for drilling rigs

Decanter centrifuge is a very important machine for oil & gas drilling rigs. Usually at least 2 sets decanter centrifuge should be used for 1 drilling rig.

The first centrifuge with middle speed acting as the fourth phase solids control equipment. It is used for recovery barite. Barite is an expensive material for drilling mud. A good barite recovery centrifuge can help to reduce drilling cost.

The second centrifuge will be used for treatment of the drilling cuttings. Usually, for OBM and SBM, it is used after vertical cuttings dryer. For WBM, after high G shaker. It is used to cover useful drilling mud from drilling cuttings.

World top decanter centrifuge model for drilling rigs:

1) Derrick (DE-1000) decanter centrifuge

2) MI-Swaco (518) decanter centrifuge

3) GN Solids Control: GNLW363 decanter centrifuge

Why choose GN brand decanter centrifuge

The former 2 brand is formerly the most famous for decanter centrifuge for drilling site for a long time. But their price is relative higher. Or say, much higher. In this case, market urgently needs a new brand with good quality, reliable service, good brand name, but more cost-effective price. GN Solids Control comes out with its most hot sale model GNLW363 and GNLW553 centrifuge. Both of the decanter centrifuge model can be matched for fixed speed or variable speed with PLC control panel.

Many drilling rig they not buy decanter centrifuge with mud recovery system as the high cost. They rent from special mud service company while needed. And they pay for every day. Actually, it is a huge cost for the long run. Now, GN Solids Control enable them another option. Contact GN now, then you can own your own centrifuge for your rigs: good price centrifuge model for option

As API certified manufacturer for centrifugal pump, GN Solids Control have all its pumps (centrigual pump, Screw pump, shear pump, slurry pump) approved by performance test before delivery. The pump test should per standard API610. It should be done with water under temperature 65℃ (150℉).

The centrifugal pump performance test should reach following requirements:

1) While doing performance test, the tested centrifugal pump should mount bearing and sealing as specified in the order.

2) If approved by the buyer, in order to not damage the sealing appointed on the order, or the test fluids is incompatible with original sealing, the pump can be test with replacement sealing

3) In any stage of the centrifugal pump performance test, it is not allowed any leakage over the rate of Standard ISO21049, or over the rate appointed between vendor and buyer.

If there is any leakage over the appointed rate during performance test, the centrifugal pump manufacturer should disassembly the sealing for maintenance. While open or disassembly the pump sealing, the operator should again do air test to the sealing.

While the centrifugal pump use water as performance test fluids, the fluids sealing suitable for water have no sign for leakage. It should double check the sealing performance per standard ISO21049:2004, and insure it is accordance with the zero visibility leakage standard.

4) If there was leakage, it should be test again after repairing the centrifugal pump sealing. And to insure the centrifugal pump have a good performance for sealing.

5) The lubrication oil pressure, temperature, and viscosity should be under the scope of the user manual offered to the buyer.

6) Regarding bearing request for pure oil mist lubrication system, it should be lubricated with suitable oil type.

7) All sealing parts and connection parts of the centrifuge pump should be checked careful to avoid leakage.

8) All alarming system, protection system and control system regarding centrifugal pump performance test should be checked, and adjust per test requirement.

After approved by all the aboved test, the centrifugal pump is qualified for delivery. That is why GN Solids Control, as one the world largest solids control and DWM manugacturing, can insure the quality of every its pump.

GNZS703D Double deck shale shaker is the advanced shaker model promoted by China leading solids control company-GN Solids Control Co., Ltd. It is widely used in waste management and compact mud system.

Waste management system application

Double deck GNZS703D shale shaker adapt high G force (≤7.5G) and a double deck. Some users choose it as a better replacement of high G shaker. It can better dry cuttings with the 2 screen deck.

Some users will request to add steam coil for double deck shale shaker while used to treat waste cuttings. GN Solids Control have experience and can customize per users requirement.

Compact mud system application.

Double deck shale shaker GNZS703D used for small mud system to make the system for compact. Usually, the bottom deck will be used as shale shaker, while the upper deck used as mud company together with desander/desilter cone assembly. the total machine takes a smaller footprint but act as 2 separated machine. And surely, the cost is much lower than a separate shale shaker and mud cleaner.

Disadvantages

Although there are many advantages, but there are also many operators they do not like double deck shale shaker, as it is not convenient to change the bottom shaker screen. It is the main problem of shaker manufacturer faced now, and need to be improved.

Construction of Bentonite mud mixing system

Bentonite mud mixing system is composed of mixing hopper and centrifugal pump.

It can be composed by 1 each mixing hopper and 1 each centrifugal pump. it is called single Bentonite mud mixer. Or 2 each mixing hopper and 2 each centrifugal pump for tandom bentonite mixer. 

Application of Bentonite mud mixing system

Betonite jet mud mixer is used to make up drilling fluid or increase total amount of the drilling fluid, change the fluid density, viscosity, and dehydration. When making up again, put the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) into the recycle tank through the jet unit. If put them directly, the materials of drilling fluid and chemical additives will be deposited largely or dump together and we can’t obtain diffused and well-proportioned drilling fluid.

Features of GNSL series Bentonite mud mixing system

GNSL series jet mud mixing device is a unit used together with the solid control system for petroleum drilling. It is suitable for drilling from 1,500 meters to 6,000 meters and can strengthen and make up drilling fluid through the fixed control system horizontally. The unit includes one sand pump, one jet mixing funnel and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently.
