摘要

针对油层岩石的机械性质,利用有限元法对射流切槽后的岩样进行应力分析,得出了钻压及切槽参数(槽宽、槽深、槽数、槽作用位置)对岩样应力分布形态的影响规律,为超高压射流合理应用于深井、超深井钻井提供了理论依据。

Abstract

In accordance with the mechanical characteristics of reservoir rocks, the finite element method is used to analyze the rock samples with jet cutting grooves. Some of the basic tendencies on how WOB and groove cutting parameters, including the groove width, depth, numbers and affecting locations effect the distribution of rock stress. This study provides a theoretical foundation for applying the super be pressure jetting technology in drilling deep wells and ultra-deep wells.
