摘　　要：江苏油田梁垛区块地层粘土含量高,页岩水敏性强,针对该区块复杂岩性以及梁X15井大井斜、稳斜段较长的特点,特选用了聚醚多元醇钻井液体系,并对其抑制性、抗温性、润滑性进行了室内评价。现场应用结果表明,该体系钻井液具有摩阻小、泥页岩抑制性强、触变性好的特点,有利于减少井下复杂的发生。The under formation of Liangduo block in Jiangsu oilfield is easy to water sensitive due to its high content of clay in shale.The polyether polyol drilling fluid is selected due to the complex formation character,large deviation and long steady section.The shale inhibitive ability, heat resistance and lubricity were evaluated before flied application.The fluid used in situ showed low friction,high shale inhibitory and good thixotropic behavior which was beneficial to reduce the downhole complex.
