Abstract
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.
