Why do we need to use a solids control system

The solid particles in the drilling fluid are divided into two types: harmful solid phase and useful solid phase. Cuttings are the most important harmful solid phase in the drilling fluid, which will affect the physical properties of the drilling fluid during the whole process of drilling, and make the drilling fluid more effective. Density, viscosity, dynamic shear, water loss, mud cake, abrasiveness, viscosity and flow resistance increase. During the drilling process, cuttings can also damage the oil and gas reservoirs, reduce the drilling speed, increase the torque of the turntable, and encounter obstacles during tripping, causing sticking and sticking, causing lost circulation, blowout and other complex downhole conditions. At the same time, the cuttings in the drilling fluid will cause serious wear to the circulation system.

The role of solids control system

Through the solid control technology, the harmful solid phase in the drilling fluid is removed, the useful solid phase is retained, and the drilling fluid performance requirements of the drilling process are met. Solid control technology is used to remove harmful solid phases in drilling fluid, retain useful solid phases, and meet the requirements of drilling fluid performance for drilling technology.

The most effective and economical method is: mechanical removal.

The solid control equipment mainly includes: vibrating screen, desander, desilter, centrifuge, and deaerator.

Solids control system It is a whole that is reasonably combined with various delayed solids control equipment according to the requirements of drilling fluid solids control technology.
