Oilfield centrifuge application scenarios
Time: 2024-05-15 Source: Solids Control Equipment Author: Mrek
Centrifuges are centrifugal separation equipment. Commonly used in drilling sites are decanter centrifuges based on solid-liquid density differences as the basis for separation. They are mainly used to remove 2~10μm solid phase substances in drilling fluids. They are the last level of drilling fluid solids control equipment.
The specifications of the centrifuge are expressed by the length and maximum diameter of the drum: there are specifications such as 18 × 24 inches, 14 × 22 inches, 14 × 20 inches (diameter × length), etc., and there are also specifications based on processing capacity. Generally, domestic centrifuges The machine processing capacity is 40 cubic meters/hour or 60 cubic meters/hour.
The drum of the centrifuge rotates at 1500~3500 rpm (r/min). The screw conveyor generally rotates in the same direction as the drum with a speed difference of 1:80. Generally, solid particles of 2 to 3 microns can be removed. For use with weighted and non-weighted drilling fluids.
Application of centrifuge to process weighted drilling fluid
The primary purpose of using centrifuges in weighted drilling fluids is to control viscosity. Because at high viscosity, drilling speed is slower. The method of controlling viscosity is to separate the ultra-fine solid particles and colloids that cause the viscosity to increase through the overflow, discharge them to the waste pool, and return the underflow containing a large amount of barite to the drilling fluid circulation tank.
Application of centrifuge to treat non-weighted drilling fluids
In unweighted low-solid phase drilling fluids, centrifugation is a very effective solid-liquid separation method. The centrifuges used in this area are usually large-capacity centrifuges that can process 23 to 45 m3 of liquid and 3 to 4 tons of solid phase per hour.
The centrifuge separates the drilling fluid into overflow and underflow parts. The underflow contains a large amount of useless solid phase and is discharged to the waste slurry tank; while the valuable liquid phase is returned to the circulation tank. Because of the huge benefits of low-solids drilling fluids, it is increasingly common to use centrifuges to remove solids from non-weighted drilling fluids.
When choosing solids control equipment such as oilfield centrifuge, choose HL Solids control. HL Petroleum solids control equipment has long service life and high cost performance. It is a trustworthy brand in the industry!
