打水泥塞是不同井况下都需要的基本作业 ,而打水泥塞作业的成功和失败具有一定的随机性。本文通过一系列试验 ,进一步解释了打水泥塞成功与失败随机性的原因 ,研究了水平井、斜井和直井条件下影响水泥塞稳定性的变量 ,提出了成功打水泥塞作业要考虑的因素 ,并根据研究结果设计了成功打水泥塞的方法。 Cement plug plugging is a basic operation required under different well conditions, and the success and failure of cement plugging operations have a certain degree of randomness. Through a series of experiments, this paper further explains the reasons for the randomness of success and failure of cement plugs, studies the variables that affect the stability of cement plugs in horizontal wells, inclined wells and vertical wells, and puts forward the factors to be considered in the successful cement plug operation , And according to the results of the study designed to successfully hit the cement plug method.
