科学使用PDC钻头的钻井技术

DRILLING TECHNOLOGY OF USING PDC BIT

通过归纳PDC钻头的特性 ,结合PDC钻头的破岩机理分析以及PDC钻头的现场应用总结 ,提出了应用PDC钻头的特殊要求和参数 ,对使用PDC钻头降低钻井成本、提高钻井速度与减少井下钻井复杂情况进行分析后认为 ,合理使用PDC钻头能够缩短钻井周期 ,降低钻井成本。

This paper summarizes the characteristics of PDC bit.Through rock breaking mechanism analysis of PDC bit and its field application,the special requirement and parameter of using PDC bit is proposed.And at the same time,field application of PDC bit shows that it can reduce drilling cost,improve drilling speed and shorten drilling cycle during drilling.
