How solids control system achieve its reciculating function ?

Drilling fluids is recirculated throughout the drilling process. As it rises to the surface, it passes through drilling mud shale shaker that screens the materials from the borehole, before being cycled back into the system that delivers mud to the head of the drill bit. This recirculation process, called as drilling mud solid control system, is designed to cut down on waste by reusing as much mud as possible. Drilling fluids solid control system is the first stage of the drilling mud recirculation process, which includes a lot of equipment, shale shaker, degasser, drilling fluids mud cleaner( consists of drilling mud desander and desilter), centrifuge, and other components, such as, jet mud mixer, mud agitator, mud gun, and mud tanks.
How solids control system achieve its reciculating function
1. Shale shaker will filter particles larger than 74 microns approximately, the hydrocyclone separators or mud cleaner will get ridof solids larger than 15 microns or the range is 15~74. Another issue is the bottom shaker screen mesh with 1st stage shale shaker.
2. The decanter centrifuge can process weighted and unweighted drilling fluid. Make drilling fluid cleaner for next drilling mud circulation.

3. The mud agitator, actually, is assistant equipment. It will keep necessary solid suspend among drilling mud, which makes drilling fluid even weight, density and viscosity. The vacuum degasser also similar with mud agitator, it is much larger than agitator also can get rid of small quantity invaded gas.
4.The mud mixing pump is another kind of equipment to mix or compound drilling fluid. It provides sufficient good property drilling mud ensure drilling fluid recalculate successfully.
KOSUN is a professional solids control equipment manufacturer in China, which establishment in 1992.KOSUN can supply shale shaker,vacuum degasser,mud cleaner, desilter,desander,decanter centrifuge,centrifugal pump, screw pump,mud tank,jet mud mixer, diesel tank, shear pump,mud agitator,mud gun,water tank,etc KOSUN has directly exported its products to the following regions: All-Russia Region, including Russia, Kazakhstan, Uzbekistan, Azerbaijan, Ukraine, Turkmenistan, Kyrgyzstan,Tajikistan, etc.; East Asia and South Asia, including Pakistan, India, Indonesia, Thailand, Burma, Malaysia, etc.; the Middle East and North Africa, including the United Arab Emirates, Kuwait, Egypt, Algeria, Libya, Sudan, etc.; America, including the United States, Canada, Mexico, Brazil, Columbia, Venezuela, etc.; Australia; Germany in Europe.

HYDROCYCLONE USED FOR MUD CLEANERS FOR OILFIELD

A mud cleaner is a type of cleaning and purifying system in a drilling system. When mud goes into a drilling system, such as one used for oil drilling, it first passes through a hydrocyclone, which is the first step in purifying the mud. After solids pass through this system, they next meet the mud cleaner, which is a mesh that has tiny holes to keep larger solids from passing through to the fluid. The mesh itself typically is made to block barite, because this is a common substance used and found in drilling. This keeps the mud from becoming too thick and stopping the drill, and it allows the larger particles to be used for other purposes.

The first step in using a mud cleaner is to send the mud through a hydrocyclone, because it would be too thick for the cleaner to effectively work with. A hydrocyclone is a device that uses force to push purified mud through the top of the cyclone as thicker particles pass through the bottom section. Anything that goes through the bottom section then meets the mud cleaner.
While a hydrocyclone can help purify mud to an extent, the mud cleaner is responsible for purifying the mud even further. The cleaner is little more than a mesh with fine holes made to let tiny particles pass through. Anything that is tiny enough to pass through the holes then meets and mixes with the purified mud expelled from the hydrocyclone.
KOSUN MD series high effective oilfield drilling fluid mud cleaner is the second or third stage drilling fluids solids control equipment of drilling fluids recycling system.This oil drilling fluids cleaner will handle the solids particle after being treated by the first grade separation equipment. The mud will be recovered and cuttings which are bigger than mud will be removed. Then the cuttings in the underflow will flow into circulation mud tanks through the screens of the drilling mud cleaner when the weighted mud passes while the particles that are bigger than mesh will be removed.
KOSUN is a professional drilling mud cleaner supplier and manufacturerin China oil drilling mud solids control industry.As the pioneer in solids control industry,KOSUN is capable of providing customers with series products ,such as oil & gas drilling fluid solids control equipment, decanter centrifuge, drilling waste management equipment and drilling security equipment.
The products we can provide except mud cleaner for oilfield and drilling fluid processing system including drilling mud shale shaker,desander, desilter,drilling fluids decanter centrifuge,vacuum degasser,mud tanks,mud gun,mud agitator,drilling mud centrifugal pumps and all the other solids control equipment,complete drilling mud system,etc.
