Bringing the well into operation with maximum productivity requires proper selection of chemicals for drilling muds. The rate and workability of penetration, fail safety, drilling-in quality are influenced by drilling mud quality and composition. It is chemically treated to obtain necessary physical, chemical and technological properties.
Components are selected according to the objectives; the quality of bore production and safety level directly depend on the adequate choice of reagents as well as on their ratio.
The main functions of the drilling fluids include:
-
Removing of drill cuttings from borehole
-
Maintaining the suspension state of drill cuttings
-
Borehole pressure adjustment
-
Wall cake building
-
Maintaining well shaft stability
-
Corrosion prevention
-
Transfer of hydraulic horsepower to the bit, lubrication and cooling
