well killing method

The article introduces how to choose well killing methods for HP gas wells.

介绍了选择高压气井压井的方法,分析了在各种井控施工风险状况下合理规避风险、选择最优压井方法和施工工艺等问题。

To solve such problem,pressure relief well killing technique and UBD were applied based on incompressible fluid and energy release laws.

在塔河油田的钻井施工中,打开奥陶系之后,经常遇到地层压力随着钻井液漏失进入储层而迅速升高的现象,特别是对于定容性构造,这一现象比较突出,使用常规压井方法,套压越压越高,钻井液密度越压越大,导致压井失败,但经过测试与地层能量的充分释放之后,压力迅速降低,这种定容性构造为钻井、压井带来了许多不确定性和诸多难题,为了解决着这一问题,利用液体不可压缩和能量释放原理,采用了泄压法压井技术和欠平衡钻井技术,通过几口井的实践证明,采用泻压法压井技术均一次成功,不仅缩短了压井时间与风险,而且大大的减少了钻井液的用量和对储层的污染,因此,对于定容性构造压井,泄压法压井技术可以成功的解决定性构造压井与钻井技术难题。
