合理设计岩屑规程保证正常钻进条件——金刚石钻进技术专题之一

Ensuring Normal Drilling Conditions with Designing Cuttings Regime Optimally

摘要:

论述了正常钻进的条件，提出了合理岩屑规程是保证正常钻进的关键和设计钻头的主要依据之一，讨论了岩屑规程与金刚石钻头唇面工作状态、孔底表面粗糙度和岩屑粒度的关系，提出了相应的建议。

Abstract:

In this paper conditions of normal drilling are discussed. It is proposed that discharging cuttings optimally is a key ensuring normal drilling and one of the main bases in designing diamond bit. The dependences of the cuttings regime upon working states of diamond bit face, bottom unevenness and chips size considered and corresponding suggestions given.
