“打滑”岩层回转钻进采用低工艺规程初探

Preliminary Study on Rotary Drilling in the Slipping Rocks with Low Process Plan

摘要:

通过对岩石破碎机理的再探讨，提出在坚硬致密弱研磨性岩层（俗称“打滑”地层）的金刚石回转钻进中采用低工艺规程，在探索和实际应用中取得很好的效果，尤其在中深孔中转速开不上去时也取得好的效果。

Abstract:

This article further discusses the rock breaking mechanism and proposes using the low process plan for rotary drilling in the hard compact weak-abrasive rock layer. Good effect was obtained in the practical application, especially in the deep hole without enough RPM.
