Oilfield Decanter Centrifuge Application in Drilling Fluids

KOSUN drilling decanter centrifuge, also referred to as a brand new type of horizontal decanter centrifuge, is one of the most important solid/liquid separation equipment in a oilfield solids control system. It can integrate each of the working procedures-feeding, centrifugal settling, unloading, and so on. Not to mention it truly is utilized for removing fine solids, recovering barites, lowering the solids content controlling the density and viscosity associated with the drilling flare ignition device to assure the fluids’ efficiency and also boost the drilling efficiency.

Decanter Centrifuge's Application in Handling Unweighted and Weighted Drilling Fluids

Decanter centrifuge separates by the work principle of centrifugal sedimentation. The drilling fields usually apply spiral settling centrifuge which works on the basis of different component densities. It mainly removes 2~10μm solid phase from the mud as the last stage in solids control system. It has shared applications in both weighted and unweighted drilling fluids.

Decanter centrifuges can be specified by the bowls’ lengths and max. diameters as 18×24 inch, 14×22 inch, 14×20 inch (diameter×length); or by the capacities, such as domestic centrifuges with capacities of 40m3/h or 60m3/h and bowl speed ranging from 1500~3500r/min

Decanter Centrifuge for Handling Unweighted Drilling Fluids

Effective separation in unweighted low-solids drilling fluids involves centrifugation and the required centrifuge which is usually large-capacity centrifuge dealing with 23~45m3/h of fluids and 3~4t solids. Drilling fluids will go into two flows in centrifuge, one of which is underflow discharging useless solids to waste pool and another overflow returning valuable fluids to mud tank. Now, centrifuge is riding a wave of popularity in purifying unweighted drilling fluids which carries enormous benefits.

Decanter Centrifuge for Handling Weighted Drilling Fluids

In this case, centrifugal separator is primarily aiming at controlling viscosity since large viscosity decelerates the speed in drilling. It overflows the impacting ultra-fine particles and colloids to waste pool, and sends back underflow with numerous barite content to the tank.
