Xi'an KOSUN drilling fluid purification method
Aug 02, 2024
In the drilling process, the drill bit breaks the rock while drilling, the drilling fluid brings the cuttings to the surface, and the cuttings in the drilling fluid are removed by solid control equipment. Even when drilling in clay layers, unnecessary clay particles need to be removed to maintain drilling fluid performance. The process of removing the solid phase content in drilling fluid is called the purification of drilling fluid.
Drilling fluid purification is very necessary, otherwise, the solid phase content in drilling fluid is too much, will have adverse consequences:
1, reduce the ability of drilling fluid to carry cuttings and drill efficiency;
2. Make the density and viscosity of drilling fluid rise unnecessarily;
3. Excessive particles in drilling fluid will accelerate the wear of the mechanical equipment of the entire drilling fluid circulation system, affect the life of the equipment, and increase the maintenance workload.
KOSUN drilling fluid purification method is through vibrating screen, desander, desilter, centrifuge and other mechanical equipment, the use of screening, centrifugal separation and other principles, the solid phase in drilling fluid according to the density and particle size of the different and separate, according to the need to choose, in order to achieve the purpose of controlling the solid phase.
