摘要
吸附卡钻事故与钻井液关系最为密切。实践证明，在大多数情况下，吸附卡钻是可以预防的：即调节好钻进液性能、降低泥饼的粘滞系数，减少钻具与井壁的接触面积。
The sticking of drilling tools by absorption is closely related with drilling fluid. In most cases, the absorption sticking can be prevented through drilling fluid performance adjusting, lowering viscosity coefficient of mud cake, and reducing contact area between drilling tools and borehole wall.
