奇偶齿鱼脊式聚晶钻头的设计及在油页岩地层的钻进效果

Design of Even and Odd Teeth Polycrystailine Bit and the Drilling Effectiveness in Oil Shale Formation

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。

Abstract:

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.
