Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud
4. 1 unit of GNSB3X2C-9J centrifugal pump
5. 1 unit of GNSLH-110C jet mud mixer with mud mixing hopper and 11KW mixing pump installed on the skid
6. 1 unit of GNZYQ1000A mud gas separator
7. ATEX electric control system for the whole system


8. Trip tank with pipelines and accessories
9. Shaker tank with pipelines and accessories
10. Mixing tank with pipelines and accessories

Drilling Rig Solids control equipments spare parts manufacturer in China

As a professional drilling rig solids control equipments manufacturer in China, we provide complete spare parts for our OEM equipments, and also replacement shaker screens for other brand shale shaker. Recently one batch of drilling rig solids control equipments spare parts are ready for maintenance of our solids control equipments. The list of spare parts including:
For Vertical cuttings dryer:


Different opening screen basket with scraper, Bell jar assembly with scraper, Rotor assembly with flights, Gearbox, pulley of power unit, air knife components, belt
The maintenance of the centralized lubrication system of GN vertical cuttings dryer is very easy, the user need to clean the oil tank regularly. If found abnormal, remove the screws at the four corners of the oil tank to separate the oil tank from others, tighten the 4 screws of the upper cover and oil tank. The mud discharged through the screen basket gap contains solid particles, which will damage the screen basket. When the solids layer increased to specific gap, the screen basket need to be replaced, otherwise the drilling cuttings dryness can not meet the technical requirement. Regularly check the wear of screen basket scraper, and adjust the gap between the scraper and the screen basket to keep the gap in a normal range.
For decanter centrifuge：


Hydraulic coupler assembly, Bearing block
For screw conveyor:
Variator, auger drive, hanger shaft


For screw pump:
Stator, rotor, universal joint, gearbox , variable speed gearbox
For VFD control panel, electrical parts and components, such as drives, PLC, pressure gauge, HMI Display unit, etc.
Except for these spare parts, we also produce replacement shaker screens for different brands shale shaker from API 20 to API 325 which comply with API RP 13C standard. If you need solids control spare parts and shaker screens, pls contact GN solids control.

GN Vacuum Degasser and Pumps for International Drilling Company

Recently one batch of GN solids control equipments are ready for shipment for international drilling company, including jet mud mixer, vacuum degasser, vacuum pump, decanter centrifuge.


Jet mud mixer is a jet shearing unit combined with mixing hopper, mixing pump, pipeline and accessories, skid on one skid, it can be used to mix drilling fluids for solids control system, liquid mud plant and mud recycling system. We can also provide customized mud mixing unit based on the materials to be mixed.


The sludge vacuum pump is a pneumatic pump which suck the material by 100% air operation without electricity power, then converts to positive pressure for discharging. This pump can be used to transfer material with high gravity and high density, solids content is up to 80%, the transfer solids size maximum 50mm or 75mm, The pump structure is simple and compact, the transfer distance is up to 500 ~1000m. We have 3 models with different flow rate, 2 models are movable, the other one is fixed with skid.


Vacuum degasser is used after primary shale shaker, which can effectively remove the gas from as cut mud, to ensure the proper mud weight. GN vacuum degasser is self contained type vacuum degasser, no need extra jetting pump, also it works as a big agitator to agitating the drilling mud. We have 2 models vacuum degasser for option, one is 270m3/h, the other one is 360m3/h.


Decanter centrifuge, GN solids control can produce 2 phase decanter centrifuge and 3 phase decanter centrifuge, for 2 phase separation decanter centrifuge, we can produce different bowl diameter with different treating capacity, including 9 inch, 14 inch, 18 inch, 22 inch, 30 inch. The most popular model decanter centrifuge is GNLW363D ,GNLW363D-VFD.
