Kosun Share the Way of Proper Use About Centrifuge

Summary: Learning what types of centrifuges can really deal with the drilling fluid and the solid material, can prevent common errors and improve the quality of the drilling fluids.

Decanter Centrifuge http://www.kosungroup.com/products/solids-control-equipment/decanter-centrifuge.html the treatment liquid is divided into two beams: the overflow (or light phase effluent) containing large amounts of liquid and the smallest solid phase; bottom flow (mud cake or heavy phase), which is composed of large and coarse particles and the solid immersion wet the solid particles of the liquid composition. When there is no overflow, with the larger solid particles remain (the desired solids barite and a low specific gravity) and put them into the drilling fluid return to "traditional centrifuge" to the addition to the low-gravity solids barite and most of the liquid composition of the harmful ultrafine particles and colloidal particles.

Although the content of solid particles ( in particular the composition measured by dry distillation ) are useful parameters, but solid rheology and the adverse effects of dehydration total particle surface area function instead of the solid particle content itself . Average particle size is smaller, the larger the surface area. Unfortunately, the particle dimensions distillation method does not tell us anything.

This increases the surface area of the solid particles correspond. Drilling fluid solid phase material by decreasing the particle size effect, even if the content of solid particles remain unchanged, which will produce quality drilling a very negative impact. We have observed how the borehole conditions deteriorate with time. When the slurry aging and its solid particles become finer, people borehole conditions that mainly because of deterioration of the solid particles of the slurry caused by the increase in surface area.

Removal of colloidal particles and ultrafine particles in addition to reducing solid plastic viscosity...
