It conductives to a better understanding of differential pressure sticking.
这有利于对压差卡钻进行更深刻的认识。
It is important to note that the sticking force is a product of the differential pressure between the wellbore and the reservoir and the area that the differential pressure is acting upon.
注意到以下这一点很重要：即卡钻力是井内流体压力与地层压力之差与此压差所作用的面积的乘积。
The Kuqa's pore pressure is very complicated and abnormal, especially the abnormally high pressure is great impact on differential pressure sticking.
山前构造地层孔隙压力复杂异常，特别是异常高压对于压差卡钻有很大的影响。
Correctly recognizing the differential pressure sticking is of great significance to reduce complex accidents of borehole, increase drilling speed and reduce the drilling cost.
正确认识压差卡钻，对于减少井下复杂事故，提高钻井速度，降低钻井成本具有十分重要的意义。
Differential pressure sticking is the most one common sticking, it brings great harm to the petroleum drilling.
压差卡钻是最常见的卡钻事故之一，它给石油钻探工业带来了巨大的危害。
Kuqa's piedmont configuration is so complex that differential pressure sticking frequently occurs, which seriously restricting the drilling efficiency.
库车山前构造地质复杂，压差卡钻十分频繁，严重制约了钻井效率。
Because its rigidity are less than the drill collar, less contact area with wall of a well, is also not easy to form differential pressure sticking.
由于其刚性比钻铤少，和井壁接触面积小，也不容易形成压差卡钻。
