With a fast and stable development, GN solids control has built up a modern and advanced manufacturing facility with headquarter building. GN highlights are describes as below.

GN solids control is the first API certified manufacturer of solids control equipment in China, also certified by ISO9001:2008, European DNV CE, Russia TR&TC, HSE; ATEX certificated or IEX EX certificate for electric control panel are optional in GN Solids control. GN Solids America LLC is the first USA based solids control company from China, and has developed partner in Australia, the Middle East, the Latin America, already exported to over sixty countries.

GN owns a 65000 square meters advanced facility, including warehouse, workshop 1 for raw material’s process; workshop 2 for assembly, workshop 3 for decanter centrifuges and vertical cutting dryers’ manufacture, and workshop 4 for painting. CNC machines are adopted in decanter centrifuges and vertical cutting dryers’ manufacturing workshop to control the quality with higher accuracy and productivity. Balance testing machine is used for rotating parts of decanter centrifuges and vertical cutting dryers to ensure safety and stability of GN product. In the painting machine, GN adopts auto powder coating line, drying and heat-treating machine, and also ball blasting machine to ensure the quality of painting. A wide yard in GN is to test solids control systems for oil and gas drilling, mud system for other kinds of drilling with water. Now a new factory is near to be finished, and ready for operation in the middle of 2015. Meanwhile, GN owns a specialized facility to manufacture screens in Asia’s largest mesh&wire city, supplying screens not only for GN shale shaker, but also replaceable screens for famous brand shale shakers such as MI-Swaco Mongoose, King Cobra shale shaker and so on.

The correct installation and use of hydrocyclone mud cleaner can filter unwanted solids from the mud to achieve controlled velocity.  It is important to use mud cleaner properly to ensure the quality of treated drilling mud.

1. The correct position of hydrocyclone mud cleaner for whole mud system is behind shale shaker which filter large solids at first step.
2. The drilling mud prior enter the hydrocyclone must be processed through shale shaker first.
3. Check the power source and once motor is start, check direction of rotation of the motor rotate in correct direction.
4. Seeking unusual noise from motors after turn on the machine
5. Secure the screen and hand feel the strength of the screen.  Initiate the test-run fluid and check if screens are intact.  Check every moving parts while machine is on
6. Clean the screen by end of each shift to prevent blockage of mesh and extend the usage life of screen
7. Stop the feeding of mud should turn off the pump first and keep on the shale shaker for another few minute and wash the screen, then shut down the shale shaker
8. Re-grease the bearing as needed for proper moving on machine parts
9. When the feed liquid pressure equal to the rated pressure, turn off the valve on the overflow tube, make the tubular value of the overflow pipe is 0.01-0.03mpa. When the feed pressure below the rated pressure, adjust the valve on the over-flow, make the tubular value of the overflow pipe is .0.02-0.05mpa.
10. For every 500 operation hours, the machines need regulator maintenances by checking moving parts and replace parts as necessary.
11. For every 4000 operation hours, the machine needs overhaul by doing maintenance list above and replace the hydrocyclone and check that insulation of electrical parts of the machine.

Desanding plant also called desanding unit. It is more and more widely used for pipe construction, micro tunneling, water well drilling, HDD, CBM, or other kind of trenchless projects. As more and more government increase the standard for discharge, drilled mud cannot be discharged directly as previous. Recovery system like desanding unit is as a necessary request of the trenchless machine and rigs.

 

There are many customers they do not use the desanding plant before, and do not have much understanding on the application and function of the desanding system. Blow is the normal question they will ask.

 

Question 1: What is the function of the desanding unit mud system? What we can get from the system?

The desanding unit is used to recovery clean mud from the drilled mud. There are big quantity clean mud in the drilling mud came out from well head. The desanding unit can be used to recovery the clean mud, and reuse it for drilling activity. It can reduce your cost on drilling mud. As most of the clean mud in drilling cuttings have been recovered by the system, it reduces the quantity of solids charge. And after separation of shale shaker and cyclone parts, the solids discharge become dryer and easy for transport.

 

Question 2: How is the desanding unit mud system working?

There are normally 2 or 3 phase separation for the dirty mud from trenchless drilling rig.

The 1rst phase solids control separation: Dirty mud will be fed to shale shaker for to separate the bigger sides solids.

The 2nd phase solids control separation: 10’’ Desander cone. Mud from shale shaker transferred to desander cone through centrifugal feeding pump, solids above 47 microns can be removed after this step.

The 3rd phase solids control separation: 4’’ Desilter cone. Clean mud from desander cone will come out from top of the cone assembly and flow to the desander tank, solids will be discharged outside the system. There will be a centrifugal pump used to transfer mud from desander tank and feed to desilter cone. Solids above 27 microns can be removed after this step.

Operator can choose to only use desander cone or desilter cone, or use both per jobsite condition.

Mixing system is optional for customer. Customer can choose to combined system with mixing, or a separation system with separate mixing, or even build the mixing system locally.
