As an Chinese industry leader in the design, fabrication and manufacturing of mud tanks,KOSUN has decades of experience serving production, drilling and offshore companies around the world. For example : CNPC、CNOOC、Sinopec and so on.The mud tank plays a important role in mechanically removing destructive solids and sediment from costly land and offshore drilling systems, and KOSUN's mud tanks are designed to assist with proper solids control. And since each mud tank can be constructed in a variety of sizes and styles based on your application requirements, it’s easy to customize our equipment to your project needs.
How to check a mud tank is ok ?
When a mud tank has manufactured,it may not be up to standard,but you don't know,How does KOSUN test for a qualified products ?firstly, we will process Sand blasting surface treatment,Secondly,we will process Anti corrosive Treatment,last,we will check the seal of mud tank ,we will inject water to mud tank filled, testing it tightness and then it can be sold to our customers.
Mud tank structure
Mud tanks are divided into square tanks and cone-shaped tanks according to the shape difference of the tank bottom. The body of the tank is made by welding the steel plate according to national standard and section, using the smooth cone-shape structure or the corrugated structure. The mud tank surface and passages are made of slip resistant steel plate and expanded steel plate. The mud tanks are made of the side steel pipe, all of the structure can be folded without barrier and pegged reliably. The surface of the tank is equipped with a water pipeline for cleaning the surface and equipment on the tank, it uses soaked zinc processing for the expanded steel plate. The ladder is made of channel steel to take responsibility the body, the foot board is made of expanded steel plate. The two-sided guard rail are installed the safe suspension hook. The mud tank is designed the standard shanty to prevent the sand and the rain. The pipeline is installed in the tank to preserve the warm air heat.
What is the role of mud tank ?
The main function of mud tank is storage, because the worked drilling fluids must stored to the next preparation or to the circulation, or to be reused.A tank is sectioned off into compartments. A compartment may include a settling tank, sometimes called a sand trap, to allow sand and other solids in the drilling fluid to precipitate before it flows into the next compartment. Other compartments may have agitators, which are large fan blades stirring the fluid to prevent its contents from precipitating.
Mud tanks play an important role in solids control system. It is the base of solids control equipments, and also the carrier of drilling fluids. Solids control equipments that are all mounted on the top of mud tanks include the followings:shale shaker,vacuum degasser,desander,desilter,drilling centrifuge,mud agitator,vertical slurry pump.
Drilling fluids flow into the shale shaker directly after it returns to the surface of the well, and the solids that are removed by the screen would be discharged out of the tank, and the drilling fluids with smaller solids would flow through the screen into mud tank for further purification. A centrifugal pump would sucks the shaker-treated fluids up to the desilter or mud cleaner for further purification. And vertical slurry pump is used to pump the drilling fluids up to the centrifuge,and mud pump would pump the drilling fluids from mud tank into the borehole after it is treated by centrifuge. And the circulation system would continues. The number of the mud tanks that are needed on the drilling rig depends on the depth of the well, and also the mud demands of drilling. Normally the shale shaker and vacuum degasser and desander are mounted together on the same mud tank as the first tank at the oilfield, while desilter and centrifuge on the second tank. Also the drilling rig has other different tank as reserve tank,emergency tank,etc.
