摘　　要：井壁失稳问题一直是钻井工程中一个复杂且带有世界性的难题,从20世纪40年代起就开始进行研究,至20世纪90年代进入了泥页岩井壁稳定的多场耦合模型的研究阶段,出现了很多不同的理论模型。系统介绍了井壁稳定的力学与化学耦合理论研究,并进行了试验方法的分析,将泥页岩井壁稳定性的化学与力学作用有机地结合起来,为井壁稳定的定量计算提供了大量依据。Wellbore instability has been complex and difficult problem in well drilling engineering worldwide,its research was started from early 1940of 20th century,a study of shale wellbore stability based on multi-field coupling model was carried out deeply in 1990of 20th century,in which different theoretical models were shale wellbore stability developed and implemented.The theoretical research on the mechanic and chemical coupling for wellbore stability is systematically introduced and its experimental methods are analyzed,its mechanical and chemical actions of shale wellbore stability are organically combined,it would provide bases for quantitative calculation of wellbore stability.
