新型金刚石造斜钻头的研制及改进

Study and Application of a New-type Diamond Kickoff Bit

摘要:

简述了配合连续造斜器使用的金刚石造斜钻头的设计方案，利用有限元软件对其水力结构进行优化。设计的新型金刚石造斜钻头经现场使用效果良好，但内径磨损严重，后经中心部位优化改进，大大改善了中心磨损问题，钻头综合性能得到了大幅提高。

Abstract:

This paper introduces the design scheme of a new-type diamond kickoff bit using with continuous whipstock. The improvement to hydraulic structure was made by finite element software. This new-type diamond kickoff bit shows a good comprehensive performance.
