The centrifuge is commonly used equipment in drilling solid control system and mud non-landing system, so what is the difference between the centrifuge in drilling solid control system and the mud non-landing centrifuge?
Drilling fluid centrifuge
Centrifuge in solid control system of drilling
The centrifuges in the drilling solid control system generally use medium-low speed centrifuges. Because the drilling solid control system uses multi-level solid control equipment, when the drilling fluid is filtered and separated from the mud vibrating screen to the true separator to the sand and mud removal machine, the mud particle size has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuge has been able to meet the needs of mud pulping.
Mud does not fall in the centrifuge system
Centrifuges in mud non-landing systems generally use high-speed centrifuges, or variable frequency centrifuges, which belong to high configuration centrifuges. The mud non-landing system is composed of drilling cuttings drying machine and high-speed variable frequency centrifuge. The mud non-landing system is located at the end of the solid control system to deal with the drilling cuttings tail slurry after the solid control system, so the drilling cuttings tail slurry has a large proportion and the solid particle size is large. Since the centrifuge is to undertake the mud after the drilling chip dryer treatment, the particle size of the mud screened by the drilling chip dryer is very large, and the requirements for the centrifuge are very high. Therefore, the use of high-speed variable frequency centrifuge is more appropriate.
The above is the difference between the centrifuge in the drilling solid control system and the centrifuge in the mud.
