mud system

Desanding plant is used to treat the mud in piling/mining or other construction field. Normally, this field don’t have much higher separation requirement as oil drilling mud treatment. With desanding plant, the 80% particles +40-70microns can be separated. This is OK for the job, and much lower cost compared with other mud treatment equipment.

Recently, we have got one order of 2sets desanding plant from domestic client. The client have used GNMS-500D desanding plant about 2 years before. They get new contract at the beginning of this year, and require more construction equipment for the job.

Compared with two years ago, we optimize the design with better performance; but sales price remains same. The working process of GN desanding plant described as following:

1) The vertical slurry pump will be installed in mud pit or waste mud tank

2) The vertical slurry pump will suck the mud and feeding to the shaker in the desanding plant down deck screen, screen mesh size about 40microns, to separate the big solids particles in the mud.

3) After that, the clean mud will drop down to the mud catch tank beneath. Then, the centrifugal pump will suck the mud and feeding to the cyclones above, to separate the small particles, about +40-70microns.

4) After the cyclones, the clean mud will drop down to the shaker screen, for another round recycling. After several times recycling, the mud is clean enough. The centrifugal pump can transfer the clean mud out to the work machine to reuse.

The model of GN desanding plant including:

  • GNMS-200D desanding plant, with 200gpm centrifugal pump (15kw motor), and 4each 4inch desilter cyclones.
  • GNMS-500D desanding plant, with 500gpm centrifugal pump (37kw motor), and 1ea 10inch desander cyclone
  • GNMS-1000D  desanding plant, with 1000gpm centrifugal pump (55kw motor), and 2ea 10inch desander cyclones.

If you have any request of desanding plant or mud system, pls contact GN Solids freely.

As the crude oil market is down, we get more business from trenchless client. More and more sets of customized mud system export to MENA region.  One client is from North Africa region, they have rich experience in American Augers drilling rig & mud system operation. And now, they are searching for more cost-effective mud system for their HDD operation. They find GN and ask for quotation and mud system drawing for 1000gpm.  As the client only like the MCR-10000 mud system design from America Augers, we offer the similar mud system GNMS-1000GXL mud system.

GNMS-1000GXL mud system contains:

3sets of shale shaker: GNZS703E-HB shaker. Each shaker model has treating capacity 500gpm. And 3sets of shaker can reach up to 1500gpm. As the client’s request, they will use two of them, and one of them as backup.

2sets of mud cleaner: GNZJ703E-2S12N.  Each mud cleaner have treating capacity 1000gpm. And 2sets of mud cleaner can reach up to 1000gpm. As the client’s request, they will use one of them for operation, the other one as backup.

3sets of centrifugal pump; two pump for feeding the cyclones in mud cleaner, and one pump for mixing hopper.

1set mixing hopper for mixing bentonite or barite.

trailer mounted mud tank with eight tyre for easy movement from site to site.

Another client from Middle East region has a smaller project, and need 100-150gpm mud system. The mud system is compact design with much cost effective equipment list, including double deck mud cleaner with coarse mesh screen, and four cyclones. The mud cleaner can remove +40microns solids particles. After mud cleaner, the clean mud will go to clean tank directly, and where bentonite or barite may also mixing there. One mud hopper and mixing pump also attached.

If you have some HDD project and need mud system, pls contact us freely.

As China high end solids control equipment, GN win good reputation in worldwide market with high quality & good price. Based on the many years brand accumulation, even during the low oil price period, GN can have good development.

1) About 1million oily sludge treatment project for Middle East

This is the first time to build oily sludge treatment system by GN Solids Control. With the help from client, GN design and modify the equipment configurations many times, and finally satisfy the need of client. The system is under commissioning in jobsite, GN sales people, mechanical engineer and electrical engineer are working for the commissioning at jobsite, together with clients.

The oily sludge treatment system mainly including feeding system, Pre-mixing and heating system, screening separation module, centrifuge module, chemical dosing module, three phase separation module, micro-bubble separation module, solids washing module etc.

We shall update to potential clients with sludge system working performance, and jobsite working videos.

Small water well rig may no need mud system, just requiring drill rig and mud pump. But for deep water well drilling, mud system is also necessary to get better drilling performance, and give better project to the drill rig bit and mud pump.

GN Solids Control mainly focus on oil drilling mud system. And we also have some client from water well drilling project, get mud system from GN; For example, client from Niger, they have 100 water wells project to improve the local life quality, and they bought the rig fro Italy Drillmec brand, and have mud system from GN.

gn mud cleaning system

Generally, we can offer 200gpm/500gp/1000gpm mud system, and we have standard model for the mentioned capacity mud system. If required by client, we can also offer customized system. Among the standard system, 500gpm mud system is the most popular, equipped with below items:

1) 1ea shale shaker GNZS703. GN Solids own patent shale shaker with 3 panel can give good performance, reliable working for the mud treatment, and we can offer coarse steel screen with much longer lifetime to fit for the system.

2) 1ea mud cleaner GNZJ703-1S8N. This unit is combination of 1ea shaker, 1ea desander cones and 8ea desilter cones. Mud cleaner, Small footprint, and 2nd and 3nd phase treatment, to remove most solids above 30microns.

3) 1ea mud hopper, the mud hopper is necessary to mix the chemicals and adjust the gravity of drilling fluids.

4) 3ea centrifugal pump. 2ea centrifugal pump is used for feeding the mud cleaner, desander cones and desilter cones. 1ea centrifugal pump working with mud hopper, to give power for mixing the chemicals.

5) 1ea mud tank to support all above mentioned solids control equipment. The mud tank is same size with container, can be locked on trailer, guarantee on the safety during transportation.

6) 1ea submersible slurry pump, this is option. The client can buy from GN the slurry pump for feeding the mud system, and even the hose to connect the slurry pump to the mud system.

The end.

Shale shaker tank is the first phase separation in drilling mud system. The performance is mainly based on the shale shaker quality, and the shaker quality is mainly based on the shaker screen working performance.

GN Solids Control is complete line solids control equipment company, even the shaker screen, it is produced by GN own workshop. We welcome visitors to check GN screen workshop in suburb of Beijing, China.

1) What kinds of shaker GN can offer ?

GN can offer shale shaker as per client’s request. We even can design shaker for client if required in large quantity. For standard items, GN have 3 type shaker model for option.

First model: 2 panel mini shale shaker, mainly used for diamond drilling / mining / piling etc. Small capacity required for shale shaker.

Second model: 3panel shale shaker, which can be used for oil drilling mud system, workover rig system, HDD etc. This model shaker is popular as good price and less consumption on shaker screen quantity. But the performance will not as good as 4 panel shakers.

Third model: 4 panel shale shaker, having similar application field as 3 panel shale shaker. With the longer shaker deck, the working performance will be much better than 3 panel shaker. However, the consumption on shaker screens will also higher cost.

14inch centrifuge

2) What kinds of shaker screen GN can offer ?
