摘要
在壳牌石油公司油页岩资源项目钻探施工中,针对复合片钻头产生滑槽式的研磨回转而出现憋泵、糊钻、烧钻、进尺慢等问题,研制了奇偶齿鱼脊式聚晶钻头,并设计了合理的水路系统,与复合片钻头相比钻进效率成倍提高。
In the drilling for oil shale resources, Shell Oil Corp. developed even and odd teeth polycrystalline bit, in order to avoid circulation suffocation, balled bit, bit-burnt, low footage, and designed rational water circuit. Comparing with PDC bit, drilling efficiency was multiple increased.
