With the increasing difficulty of oil drilling development, more and more oil-based muds are used in drilling, but oil-containing drilling cuttings will be generated during the use of oil-based muds, which will cause great harm to the environment. Most countries in the world have strict restrictions on the discharge standards of oily drill cuttings. The cuttings dryer, centrifuge, screw conveyor and screw pump sold to customers in the Middle East will be used in the treatment of oil-based drilling mud to meet customer requirements.

1. GN Solids Control oil-based vertical cuttings dryer

The cuttings dryer uses the centrifugal force generated by mechanical rotation to realize the separation of solid-liquid mixture, and can recover the liquid phase in the cuttings. Drill cuttings pass through the feeding port and enter the space between the screen basket and the screw through the distribution plate. The rotating speed of the GN cuttings dryer is up to 900RPM and the separation factor is 420G. Under the action of centrifugal force, the liquid phase and small particles (centrifugal liquid) pass through the material layer, pass through the screen basket, and flow along the upper cover into the upper part of the machine base. The solid part of the drill cuttings is kept inside the screen basket, because there is a speed difference between the rotor scraper and the screen basket, the rotor scraper will remove the drill cuttings from the screen. The screen basket is scraped off and pushed to the bottom of the screen basket, so that the dehydrated drill cuttings are discharged into the collecting funnel under the machine or the bottom screw conveyor.
