“刚柔”钻具组合在新疆油田八区的应用

Application of Flexible Bottom Hole Assembly in Eight Rrgion of Xinjiang Oilfield

摘要:

在易斜地层钻进时，带稳定器的钟摆防斜钻具组合的防斜效果往往不甚理想。通过计算和实践，发现“刚柔”钻具组合钟摆力强、防斜降斜效果好，而且可在常压下钻进，既保证了井身质量又提高了机械钻速。为大倾角硬地层易斜区防斜打快提供了一种新型的钻具组合类型。

Abstract:

The results of inclining-prevention are not so ideal while drilling in easily declined formations by pendulum assembly with stabilizers. It was found in continuous practices and calculation, the flexible bottom hole assembly has the advantages of strong pendulum force, good incllning-prevention results, and which ensure the well bore quality and improve ROP. A new type bottom hole assembly is provided for drilling in high angle deviated and hard formation.
