Category Archives: Drilling Mud Cleaning System

As a mud tank and solids control system manufacturer, with location in China, DC designed mud tanks for over 20 countries in the world. DC oil drilling solids control system is consisted of a group of mud tanks and solids control equipment.

The mud tank is to store the drilling mud for circulation, and the solids control equipment is for cleaning the drilling solids, mixing drilling mud, or agitating the drilling mud. The mud tanks design including the construction of the mud tanks, selection of the solids control equipment, layout of the pipelines etc.

Mud tank types in the Solids Control system:

No. 1 Mud tank is normally the Shale Shaker tank ( Sometimes there is an extra small tank which called trip tank will the No. 1 tank)
No. 2 Mud tank is the active mud tank.
No. 3 Normally is the mud suction tank for the suction of mud pumps.
No. 4 Mud tank is the mud mixing tank

Selection of Solids Control Equipment for the mud tank.

The selection of the solids control equipment for the mud tank is also depends on the drilling rig size and drilling conditions. List of the main solids control equipment for the drilling rigs are as below:
1) One Each ZYQ1000 Mud gas Separators
2) Three Each of DCS700-3 Linear Motion shale shakers for 1500 GPM handling capacity
3) One each of DCZCQ270A vacuum degasser
4) One each of DCQJ250X3/100X16 mud cleaner which including 3 ten inch desander, 16 four inch desilter for the capacity up to 1500 GPM.
5) Two 75HP DCSB8x6 centrifugal pumps for feeding the mud cleaner, and two 75 HP mixing pumps for the mixing hoppers.
6) One middle speed DCLW450 decanter centrifuges for barite recovery or high gravity solids separation.
7) One high speed DCLW363BG decanter centrifuge for low gravity fine solids separation.

Besides the solids control equipment, the mud tank should also have the mixing and agitation device. On the low pressure mud rolling lines a sufficient number of bottom DCNJQ series mud guns complete with nipples, pipes, butterfly valves, hammer unions and a handle to rotate the mud gun from mud tank surface etc

in addition to this, DC Solid control can design a complete mud circulation system acoording to uers request, and provide you the 3D flow draw for your confirmation. So if you have interest with it please contact us by email adela@dcmudcleaningequipment.com

Along with the drilling fluid, a reliable method of delivery to the drill is needed. This is called a mixing system or mud system. The mud system delivers the fluid to an onboard pump (on smaller horizontal directional drills) or a standalone pump that feeds into a larger rig (generally 100,000-pound capacity or larger.) With the rise of mud recycling in drilling, reclaimers are becoming more prominent on jobsites.

These are a type of mud system that “cleans” the used mud and recirculates it back into the mixing system to be reused. An HDD contractor needs to make sure to use the right kind of mud and the proper equipment to effectively supply the correct amount of fluid into the pump and downhole.

mud system

Rising costs of mud disposal and the limited availability of disposal sites are driving some HDD contractors to reuse their drilling fluid, which requires a reclaimer. Environmental concerns are also a factor so we are seeing more reclaimers required in drilling specs,” says Heinen. “Also mud disposal is cost prohibitive and we are seeing an increase in mud recycling requirements on job sites.”

The reclaimer is generally configured with multiple tanks which can include a clean mud tank, a dirty fluid tank and a desander and/or desilter tank. Dirty fluid is drawn from the return pit and pumped across the first cut shaker(s), which sift out all the larger particles of sand and debris. Then the fluid is pumped through the desander cones where a cyclonic motion is used to eliminate even smaller particles, and again across a shaker screen equipped with a finer mesh screen to further the cleaning process. The fluid finally passes through desilter cones and again across a final set of shakers and screens, which separate out the smallest micron particles from the drilling fluid completing the cleaning process. Each deck on the reclaimer uses progressively smaller screens to remove micron-sized elements from the fluid.
Once through, the fluid is stored in the clean mud tank ready to be recirculated back down hole.

DC Solid control can provide the professional guidance please contact us to get more info about it.

Mud Tank System is a part of circulatory system of the rig, used for storing and feeding the required drilling fluid during Rig operation cycle. Mud Tank System is available for different drilling rig sizes from 250HP to 3000 HP with different capacity.

Normally, a complete mud tank system consists of a mud tank with compartments for both incoming dirty and cleaned fluid, a shale shaker, a desander (depending upon the size of the unit), and a desilter. The shale shaker separates larger solids approximately 400 micron and larger, the desander separates solids approximately 100 micron and larger, and the desilter separates solids approximately 40 micron and larger. After the fluid processes through the desilter and deposited into the clean tank, it can then be pumped to the mud pump to be pumped back downhole.

DC mud recycling systems feature an all-in-one unit design, and the use of mud recycling has proven beneficial when used with mid to large size directional drilling rigs. The ability to continuously recycle drilling fluid and decrease the solids slurry waste saves costs associated with new fluid use and less waste for contractors to pay to haul off. The cost savings and environmental friendly impact is a significant trend being seen across the industry.
