Decanter centrifuge in drilling solids control system

Decanter centrifuge is used to separate suspended solids with diameter ≥2μm in drilling solids control system. Normally, the underflow (cake, heavy slurry) is discharged while centrifuging unweighted fluids. The overflow (centrate, effluent, light slurry) containing most of the viscosity-building colloidal particles, is discharged from weighted fluids. Accordingly, decanter centrifuges shall be installed in a manner that permits either stream to be discharged, and either to be returned to the active drilling solids control system.

With weighted drilling fluids, decanter centrifuges are used to control low-shear rate viscosity and drilling fluid quality by removing colloidal and near-colloidal particles in the overflow. They shall be operated as long and as often as necessary to control low-shear rate viscosity, as well as plastic viscosity.

KOSUN DC450L decanter centrifuge is a common model in drilling solids control system.

Drilling solids control system

Drilling solids control system is used to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface in drilling rig. Normally drilling solid control system is consist of five stages, including shale shaker, vacuum degasser, desander, desilter, decanter centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as mud cleaning system. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big mud agitator. All these solids control equipments are mounted on the top of the mud tank. After separating the solids, the cleaned mud would be pumped into the borehole again.
