摘　　要：针对泥页岩发育的地层,国外石油公司研制出了一种高效泥页岩抑制剂——胺类化合物,并以此为基础构建了高性能水基钻井液体系。介绍了胺类抑制剂的作用机理和目前几种用于胺类抑制剂的评价方法,并指出了这些方法的优缺点。通过室内实验建立了一种定量评价钻井液用胺类抑制剂抑制性的新方法——析水率法。室内测试了3种胺类抑制剂在不同膨润土基浆中的析水率,并与膨润土抑制实验结果进行了对比,2种方法的结果非常吻合。For high shale content formation,a high performance water-based mud is developed and formulated in which a suitable amine agent has been successfully added to the system as a strong shale inhibitor.The mechanism and evaluation methods of the amine agent are introduced.A novel quantitative evaluation method is developed,based on the principle of free water separated in bentontie system that contains amine inhibitor.In laboratory,the experimental results show that the water separated principles of 3 kinds of inhibitor fit very well with the bentonite inhibition tests.
