Abstract

The invention provides polyether amine alkyl glycoside with the structure as shown in the formula I; in the formula I, m is 1 to 16, n is 1 to 3, R1 is alkyl of which the carbon atomic number is 1 to 10 and R2 is methyl or ethyl. The invention provides a preparation method of polyether amine alkyl glycoside adopting the technical solution; the method comprises the following steps: reacting chlorinated epoxides, dihydric alcohol compounds, water and acid catalysts to obtain a reaction product; reacting the reaction product with organic amine to obtain an intermediate product; reacting the intermediate product with alkyl glycoside to obtain polyether amine alkyl glycoside. The polyether amine alkyl glycoside provided by the invention is good in inhibition performances and lubrication performances and can be applied to drilling fluid. Polyether amine alkyl glycoside is added in the drilling fluid, so that the problems of easy sloughing formation of strong water-sensitive shale, sandstone-mudstone interbedding and basalt-mudstone interbedding and the like can be solved by the drilling fluid. The polyether amine alkyl glycoside is suitable for well drilling construction of a shale gas horizontal well.

Description

technical field [0001] The invention relates to the technical field of alkyl glycosides, in particular to a polyetheramino alkyl glycoside and its preparation method and application. Background technique [0002] Alkyl glycosides are mainly used in daily chemical products, textiles, leather auxiliaries, paper-making auxiliaries and other industries, and began to be used in drilling fluids in the 1990s; the earliest report on the application of alkyl glycosides in drilling fluids appeared in 1994 in At the IADC\SPE Drilling Engineering Conference held in Dallas, USA, the research results of alkyl glycoside drilling fluids aroused widespread attention from the participants; After more than ten years of development, the alkyl glucoside drilling fluid has made great progress; at present, the methyl glucoside drilling fluid has formed a relatively mature system, such as the Chinese patent application number 201310522827.4 which discloses a drilling fluid The preparation method o...
