摘　　要：本文是根据 80年代中期以来我国发表的期刊文献资料写成的一篇综述 ,分四大类介绍了这一期间研制和开发应用的钻井液降粘剂及对其作用机理的研究。这四大类降粘剂是 :①以木质素、栲胶、单宁等天然原料为基础的降粘剂 (13种 ) ;②聚合物降粘剂 ,包括含马来酸 (酐 )或丙烯酸的共聚物 (6种 ) ,含磺酸基团的共聚物 (3种 ) ,两性或阳离子型聚合物 (4种 ) ;③无机降粘剂 (磷酸盐类 ,有机硅类 ) ;This is a review article based on the recently published data since mid 1980s. The drilling fluid viscosity reducers (VRs) developed and used in drilling practice are presented in four classes and the mechanisms involved in functioning of every class are discussed. The VRs reviewed are:①lignin and tannin derivatives(13 names);②polymers(6 maleic or acrylic acid copolymers;3 sulfo copolymers; 4 amphoteric or cationic polymers);③inorganics(phosphates and silicone compositions);④VRs for MMH mud.
