1. Shale shaker will filter particles larger than 76 microns approximately, the hydrocyclone separators or mud cleaner will get rid of solids larger than 15 microns or the range is 15~76. 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.
Above are main solids control equipments and their effects. Others equipments will be described in other articles.
Solids control application
We are rather familiar with oil and gas drilling fluid solids control system. Furthermore, solids control has rather wide range applications , such as HDD Mud recycling, the water well drilling, Geothermal well drilling, piling project, tunneling or pipe construction, the CSM exploration, mining industry, slurry separation, etc. But, different industries will have differential name to it. Maybe it is the drilling mud process unit, the drilling fluid purification system, drilling fluid circulation, sludge/dredged slurry separation system, etc.
