本文在介绍水压致裂原地应力测量基本原理的基础上,介绍了一种特殊形态的水压致裂应力测量记录曲线,详细分析了这种曲线形态形成的岩石背景条件和形成机理。笔者还就如何判断曲线的重张和闭合压力提出了自己的观点。最后对研究这种特殊形态的记录曲线的意义进行了展望。
Based on the introduction of the basic principle of in-situ stress measurement by hydraulic fracturing, this paper introduces a special form of hydraulic fracturing stress measurement and recording curve, and analyzes the rock background conditions and formation mechanism in detail. The author also put forward his own views on how to judge the tension of the curve and the closing pressure. Finally, the prospect of studying the recording curve of this special form is prospected.
