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

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.

GN Desander and Desilter Centrifuge for China Drilling Company

Recently one unit of desander desilter centrifuge is ready for shipment to China drilling company.


GN Desander and Desilter Centrifuge is an efficient solids liquid separation equipment mainly used to remove solid particles such as sand and mud in drilling fluids. It is a specially designed big bowl decanter centrifuge, which separates solid particles from drilling fluid under centrifugal force through components such as a rotating bowl and a screw propeller, and discharged from solids discharge port and fluids distribution port. The Desander and Desilter Centrifuge has the advantages of wide separation particle size range, large treating capacity, compact structure, and simple operation. It can be used to replace the desander desilter mud cleaner more efficiently, with higher separation efficiency and better quality of recovered drilling fluids. The desander and desilter centrifuge has a wide range of application prospects in fields such as oil drilling, which can effectively improve the solids control quality and drilling efficiency of drilling fluids, and reduce the drilling costs.


GN decanter centrifuge applications including oil and gas drilling solids control system, drilling waste management system, oil sludge treatment plant, HDD mud recycling unit, Mining tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation and other mud treatment. GN can provide CNEX, IEC EX, ATEX explosion proof motor and control panel for your option. The bowl and screw propeller rotate in the same direction with a certain differential speed, under the centrifugal force, solid phase is dropped on the bowl wall to form sediment layer, then push to the cone section and discharge through the solids discharge port.
Except for desanding desilting centrifuge, GN solids control also produce linear motion shale shaker, mud cleaner, vacuum degasser, 3 phase decanter centrifuge, vertical cuttings dryer, screw conveyor, centrifugal pump, mud agitator, mud tank system, etc solids control equipments.
