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.
