The choice making of use mud cleaner that contain desanders, desilters and shale shaker is concern of operation cost and the space allowed for the machinery.  It serves the purpose to remove the needed-remove solids in the drilling mud to keep the mud in high performance as needed. It is placed after shale shaker and vacuum degasser filtering the mud after initial filtering large solids and removes the gas that contain in the mud.

Turn the motor on and start pay attention on the rotation direction of the motor.  The motor need to be rotated in opposite directions and need to be marked on the motor direction after the confirmation of the check.  The operator at this stage need to pay attention on the sound that is from the machinery and if unusual sounds appear it needs turn off the machine and check the motors and tightness of the screens.

Operator need to perform routine check of motor bearing, the seals and lubrication of every moving part and fill the oils if necessary.  Such routine check need to perform after intense use of machinery to prevent structural damage that will most likely put the cleaning mud operation in stop.

To keep costs of operation in consist, shaker screen need to be flushed to clean the surface.  In some case of high viscosity of cleaning drilling mud, it also need to check the damage of the mesh as well after the flushing it with water.

Operator need to stop the feeding of the sand pump and let the shale shaker idle for period of times, rinse with water and timely clean the surface of the screen then stop the shale shaker motor.

Like the shaker screen, hydrocyclone is another replacement parts that need the cleaning like the screen after each shift of use.  This check to see if large objects are causing jamming that leads to shorted the use life of hydrocyclone.

The 18th China International Petroleum & Petrochemical Technology and Equipment Exhibition

Profile of exhibition

China International Petroleum & Petrochemical Technology and Equipment Exhibition (CIPPE) is an annual gathering of petroleum and petrochemical industry. With a magnificent exhibition space of around 90,000 square meter, 18 national pavilions, 1,800 exhibitors and over 110,000 professional visitors from 65 countries and regions.  CIPPE has become the largest petroleum exhibition in the world.

GN Solids Control LTD advantage is we are the solids control manufacture that made the whole  solids control machinery  our-self  plus we custom made the whole mud recycle system to meet specific project’s need for our customers.  Our customer are ensure we provide the solids control machinery to meet local environmental standard around the world and dealing with manufacture them self to ensure the best possible price to keep overall cost of rig operation as consist as possible.  We provide consist stocks of parts and tech personals ready at the request of customers by moment’s notice.  There are lots of manufactures in China who can make less-costly machinery and system but adding other facts for operation consideration, GN Solids Control LTD is the choice of obvious.

GN Solids Control LTD will exhibit at: New China International Exhibition Center, Beijing

• Date: March 27 – 29, 2018
• 88,Yuxiang Road,Tianzhu,Shunyi District,Beijing. Exhibition Hall E2, Booth E2168
• GN Solids Control LTD will exhibit replacement brands shale shaker screen, decanter centrifuge, complete mud system, shale shaker and various pumps.

GN Solids Control LTD manufacture full lines of solids control machineries and its replacement shale shaker screen for itself and major brands.  .  We offer full lines of shale shaker screens in composite frame that will be acid resist and last longer than steel frame screen  in house to become single supply source of drilling operation.

As a drilling fluids cleaning decanter centrifuge manufacturer in China, GN solids control keep improving the quality and design of our decanter centrifuge to meet the requirement for different clients and different applications. GN solids control brand is the top brand for solids control drilling fluids recovery, oil sludge treatment, oil recovery, drilling cuttings management. We can meet the different requirement for customized voltage and frequency, and explosion proof standard, like IEC EX, ATEX, CNEX for class 1 div 1.

We can produce 9 inch, 14 inch, 18 inch, 22 inch, 30 inch decanter centrifuge, VFD decanter centrifuge is suitable for drilling waste management system, because the drilling fluids conditions are changing all the time, you have to use different frequency to change the differential speed and pump flow rate to keep the centrifuge working smoothly.

GN solids control second new facility with high advanced workshop to produce decanter centrifuge and vertical cuttings dryer, we owns balancing machine for middle speed, high speed, big bowl centrifuge high speed for different size decanter centrifuge.

The CNC machines can produce centrifuge bowl components by ourselves, the bowl material is centrifugal casting by duplex stainless steel 2304, better than stainless steel 316L, 304. The screw conveyor is made of SS304, the impeller opening is help to improve the treating capacity effectively. The tungsten carbide tiles can protect the centrifuge impeller from danaged, and it is repairable while it is broken.

The bowl lifting bracket is to protect the bearing during road transportation and sea freight, which is the most important and expensive parts for the whole centrifuge.

The important important issue for the decanter centrifuge working life is the centrifuge bowl assy, welcome to visit GN solids control centrifuge workshop to watch the production process of our decanter centrifuge, the faclity is located in Beijing, about 30 km from Beijing Airport.

Centrifuges is widely used for oil gas driling, piling projects. In whihch applications, big bowl is more and more popular, eg. 30in decanter centrifuge GNLW764 from GN Solids Control is known to more and more piling contractors. In this CIPPE 2017, GN will bring one unit to Beijing.

As for HDD projects, lots of people have tried, but it is not quite modularized, as too many different requirement based on that. For the strict applicaition, GNLW553, GNLW554 should be good options, because of the high flow capacity. Polymer is a good help for the not too high speed, concentrate the small solids, while lots of places do not like chemicals in disposal.
So what do we need in HDD mud system, that depends, but basically a few points as listed:
– recycle the water
– reuse the solids
– dump the solids (with / without chemical)
– dump water to water treatement plant
Some important index will be:

• moisture of the solids (1 – dry solids / total)
• TSS (total suspended solids) in water result

Then if we can figure out what equipment is using before centrifuge, and how is the performance, then we will find out if we need use the centrifuge continuously or not, which is important for definning the capacity.

A separate skid is a very flexible choice for HDD projects, as normally it is not in the system, not with the rig package, so far it is a customize solution. And with a flexible frame, will be easier to arrange the solids / liquid discharge.
