复合型井下动力工具应用实践

Application Practice of Compound Underground Power Tools

针对新疆油田二叠系、石炭系等地层研磨性高、可钻性差、机速低的问题,采用复合型井下动力工具,优选高效PDC钻头,取得了较好的提速效果。介绍了复合型井下动力工具及在金112井等4口井应用情况,总结了好的成功经验,并对下步改进提供了可行性建议。

Aiming at the problems of Permian and Carboniferous strata in Xinjiang Oilfield, the grinding performance is high andthe drilling speed is low and the machine speed is low.By using compound downhole power tool and high efficiency PDC bit, the effectis improved.This paper introduces the application of compound downhole power tools and four wells in gold 112 wells, summarizes thegood and successful experience, and provides feasible suggestions for the improvement of the next step.
