This pertains to the technical field of lubricants, and particularly relates to a composition for preparing a wear-resistant drilling fluid lubricant, a preparation method of the wear-resistant drilling fluid lubricant and a drilling fluid. Vegetable oil, nanometer calcium borate, an ether compound and an amine compound may be used as raw materials to prepare drilling fluid lubricant with excellent abrasion resistance by reasonably controlling dosages of the raw materials. The lubricant provided can improve wear resistance, lubricating property, and high temperature resistance of bentonite slurry and water-based drilling fluid.

Composition for preparing anti-wear lubricant for drilling fluid and preparation method of anti-wear lubricant for drilling fluid and drilling fluid

A sulfur- and phosphorus-free extreme pressure lubricant and a preparation method thereof is disclosed. The lubricant is prepared by using Turkey red oil, a cyclic anhydride compound, triethanolamine, nano polytetrafluoroethylene powder, an alcohol compound, and water as raw materials. The lubricant does not contain hazardous substances such as sulfur and phosphorus. This reduces the harm to the environment, equipment, and human body, and conforms to the development trend of modern industrial production. Moreover, the lubricant has excellent extreme pressure performance, and can effectively reduce the downhole friction and torque, thereby meeting the construction requirements of extended reach wells and horizontal wells.
