摘　　要：随着石油工业的发展和浅层石油资源的消耗,油气勘探开发技术不断趋向于深井和超深井钻探工艺。然而深井底部的高温会导致钻井液出现分散、聚集、钝化现象,使得钻井液的黏度增加、流动性变差,这为深井钻井作业带来了巨大的技术挑战。钻井液用抗高温降黏剂可以降低钻井液的黏度,调节钻井液的流变性,在保持钻井液稳定性和钻井效率方面具有重要作用。合成聚合物类降黏剂具有分子结构可设计性强、抗高温性能突出等特点,广泛用于抗高温钻井液。本文综述了合成聚合物类抗高温降黏剂的研究现状,介绍了羧酸类、磺酸类、羧酸磺酸类、两性离子类降黏剂的抗高温性能及降黏机理,可为新型抗高温降黏剂的分子设计提供参考。With the development of the oil industry and the exhaustion of shallow oil resources,recent oil and gas exploration has tended to focus on the drilling technology for deep and ultra-deep wells.However,the high tem-peratures at the bottom of deep wells will lead to the dispersion,aggregation and passivation of the drilling fluid,which will increase its viscosity and reduce its fluidity.This has resulted in great technical challenges in deep well drilling operations.Anti-high temperature viscosity reducers can reduce the viscosity and adjust the rheology of drilling fluids,which can play an important role in maintaining their stability and efficiency.Synthetic polymer vis-cosity reducers have the advantages of strong tailorability of molecular structure and excellent high temperature resistance,and are widely used in high temperature drilling fluids.In this paper,recent research progress in the use of synthetic polymer viscosity reducers in high temperature drilling fluids is reviewed,and the high temperature resistance and the mechanisms of viscosity reduction for carboxylic acids,sulfonic acids,carboxylic acid-sulfonic acids and zwitterionic viscosity reducers are compared.This study provides a reference for the design of new anti-high temperature viscosity reducers.
