Abstract

The invention provides a production method for anti-sloughing lubricating solid polyalcohol used for a drilling fluid. The production method is realized by compounding the following six substances: a surfactant PE, sodium lignosulfonate, polyacrylonitrile-ammonium salt, a surfactant L62, a surfactant span 80 and an antifoaming agent xp, wherein the mass ratio of solid materials of the surfactant PE to the sodium lignosulfonate to the polyacrylonitrile-ammonium salt is 1: 1: 1; the mass ratio of liquid materials of the high-purity and high-concentration surfactant L62 to the surfactant span 80 to the antifoaming agent xp is 5: 5: 2; and the mass of the solid materials is 9 times of the mass of the liquid materials. The invention has the following advantages: the production process is simple to operate and facilitates environmental protection; and the product produced by using the method provided by the invention has good dispersity, water solubility and compatibility, is economical and practical, and is convenient to use.
