Drilling fluid plays a pivotal role in oil drilling and production. Its main functions are: (1) Clean the bottom of the well and carry cuttings; (2) Cooling and lubricating the drill bit and drill string; (3) Form mud cakes to protect the well wall; (4) Control and balance formation pressure, etc. Adding high-quality micronized wax dispersion to drilling fluid can significantly improve its inhibition and lubricity, prevent well collapse and increase drilling speed.
