| 摘 要： | 室内评价了酯基钻井液的页岩抑制性，并对基液类型与页岩抑制性之间的关系进行了探讨。研究结果表明，酯基钻井液的页岩抑制性介于柴油基钻井液和水基钻井液之间，比前者弱，比后者强；基液类型与页岩抑制性之间存在一定的关系，提出用偶极矩这一化学尺度将基液划分为强、中、弱3种具有不同页岩抑制性的类型。

| Abstract: | In this paper, the inhibitive ability of ester-based drilling fluid is evaluated in lab, and relation between the type of base fluid and shale inhibitive ability is investigated. Results show that the shale inhibitive ability of ester-based drilling fluid is between those of diesel-oil-based and water-based drilling fluid, and certain relation exist between the type of base fluid and shale inhibitive ability of drilling fluid. A new viewpoint is proposed that base fluids can be divided into 3 types with different inhibitive ability by using dipoles. |
