Problems solved by technology

[0003] Generally, mixing crude oil, diesel oil, white oil and other mineral oils into the drilling fluid can better meet the requirements of downhole lubrication and anti-seize, but with the increasingly stringent environmental protection requirements , the application of mineral oil lubricants is limited
Moreover, mixing mineral oil in the high-density drilling fluid does not significantly improve the lubrication effect of the drilling fluid
In addition, although the existing vegetable oil esters and animal oil lubricants have significantly reduced the lubricating coefficient of low-density drilling fluids, they have little improvement in the lubricating performance of high-density drilling fluids.
[0004] Generally speaking, the lubricants provided by the prior art cannot well meet the requirements of high-density drilling fluid lubricating performance

Abstract

The invention provides a preparation method of sulfanyl glyceryl glucoside. The preparation method comprises the following steps: 1) under the action of an acidic catalyst, enabling glyceryl glucoside, an alkylene oxide compound, a chlorinating agent and an epoxy chloroalkane compound to react to obtain glyceryl glucoside polyether; 2) enabling the glyceryl glucoside polyether and organic amine toreact to obtain polyether amine glyceryl glucoside; 3) enabling the polyether amine glyceryl glucoside and sulfonated castor oil to react to obtain the sulfanyl glyceryl glucoside. According to the preparation method provided by the invention, on the basis of keeping the glyceryl glucoside environmental-friendly and lubricated, a polyether amine group and a sulfonated castor oil group with a sulfonated group and a long-chain alkyl group are introduced into a glyceryl glucoside molecule to obtain the sulfanyl glyceryl glucoside, so that the difficult problem that the lubricating property of current high-density drilling fluid is relatively poor can be solved. The invention further provides the sulfanyl glyceryl glucoside and the drilling fluid.

Description

technical field [0001] The invention belongs to the technical field of drilling fluid treatment agents, and in particular relates to a sulfoglyceryl glycoside, a preparation method thereof and drilling fluid. Background technique [0002] In recent years, with the oil and gas exploration and construction of medium-deep wells, ultra-deep wells, high-pressure shale oil and gas horizontal wells and other high-temperature and high-pressure wells, there are more and more high-temperature and high-pressure wells. Temperature resistance and density requirements are getting higher and higher. Under the condition of high temperature and high density, the requirements for the lubrication and anti-seizing of drilling fluid are getting higher and higher. [0003] Generally, mixing crude oil, diesel oil, white oil and other mineral oils into the drilling fluid can better meet the requirements of downhole lubrication and anti-seize, but with the increasingly stringent environmental prote...
