EP lubricant is a high efficiency lubricant for drilling fluid, which can effectively improve the lubricity and extreme pressure performance of drilling fluid. The appearance is brown transparent liquid. The drilling fluid is adsorbed on the surface of drilling tools in the form of oil film to reduce torque, improve the lubricity of drilling fluid and mud cake and prevent sticking; The product has good lubricity, suitable for fresh water, salt water, sea water drilling fluid, and good compatibility with other treatment agents.
