After the oil-based mud returns from the well through the vibrating screen, the mud liquid phase enters the circulation system for continued treatment and use, the mud solid phase enters the filter dryer (filter separator) rock chip dryer through the screw conveyor, after the filter dryer separation, the mud solid phase is taken into the rock chip box by the screw push, the mud liquid phase flows into the liquid storage tank is pumped into the vertical centrifuge for secondary treatment. The liquid phase of the mud enters the circulation system, and the solid phase of the mud is pumped into the cuttings box through the screw pump.

In the secondary treatment, the selection of a centrifugal separator must be based on the size and concentration of solid particles in the suspension, the density difference between the solid and the liquid, the viscosity of the liquid, the characteristics of the filter slag, and the separation requirements for a comprehensive analysis, the initial selection of which type of centrifugal separator. Generally, for suspensions containing particles with a particle size greater than 0.01mm (the maximum screen mesh number for the platform is 320 mesh, and the particle size is about 0.044mm), filter centrifuges can be selected; For fine particles or compressible deformation in suspension, sedimentation centrifuge should be chosen; This is also the basis for determining the position of the drill chip dryer and centrifuge in the process. At the same time, due to the suspension of compressible deformable filter slag, under a certain separation factor, the gap between the filter slag layer and the filter medium will be blocked, and the centrifuge-treated cuttings can not pass through the cuttings dryer again.

The cuttings dryer is designed to reduce the operator’s total drilling fluid cost and limit the amount of waste handled.

Recover drilling fluid directly from cuttings and weight mud from shaker mesh to avoid loss of weight mud due to shaker failure, rig movement or screen blockage. The centrifuge helps meet certain cuttings liquid discharge requirements that must be complied with. The cuttings dryer is a continuous screen centrifuge with automatic feed control and is designed for solid-liquid separation. The cuttings dryer is designed to recover the liquid phase drilling fluid from the cuttings by applying a high centrifugal acceleration force to the cuttings to improve the separation of liquid from the cuttings. The cuttings dryer can help save money on expensive drilling fluids by returning the expensive liquid phase in the mud system through further purification.

The KOSUN drilling cuttings treatment system recovers beneficial mud and returns it to the in-service mud system. The KOSUN drilling cuttings treatment system works well for diesel, mineral oil and synthetic oil-based mud. KOSUN drilling cuttings treatment system has a higher mud value, and the vertical centrifuge is a more critical equipment in KOSUN mud treatment system, which also makes the vertical centrifuge more attractive from an economic and practical point of view. In addition, the vertical centrifuge reduces the amount of waste and disposal costs incurred at the rig site.
