KOSUN Oil and Gas Drilling Solids Control System

Apr 26, 2022

The solid particles in the drilling fluid are divided into two types: harmful solid phase and useful solid phase, and cuttings are the main harmful solid phase in the drilling fluid, which will affect the physical properties of the drilling fluid during the whole drilling process and make the drilling fluid Increased density, viscosity, dynamic shear, water loss, mud cake, abrasiveness, viscosity and flow resistance. During the drilling process, the cuttings will also damage the oil and gas layers, reduce the ROP, increase the torque of the rotary table, and encounter resistance during tripping, resulting in sticking and sticking, causing lost circulation, blowouts and other downhole complex situations. At the same time, the cuttings in the drilling fluid can cause serious wear to the circulatory system.
 
Oil and Gas Drilling Solids Control System
 
The role of the drilling fluid solids control system: remove the harmful solids in the drilling fluid, retain the useful solids, and meet the drilling fluid performance requirements by the solids control technology. 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.
The most effective and economical method is: mechanical removal.
The solid control equipment mainly includes: shale shaker, desander, desilter, centrifuge, deaerator.
Drilling fluid solids control system: It is a whole which is reasonably combined by various solids control equipments according to the requirements of drilling fluid solids control process.
