Product Overview
Agent for using in drilling mud to prevent drilling with clays is a polyether polyol lubricant. This product has good lubricity and can significantly reduce the lubrication coefficient and adhesion coefficient of drilling fluid. This product is non fluorescent, non-toxic, and does not pollute the environment. It is an excellent lubricant for preparing dual protection drilling fluid and completion fluid. It can be directly added to various water-based drilling fluids, with a recommend dosage of 1%~3%。
