摘　　要：基于经典的Nolte方法,利用净压力分析法,同时提出了净上覆压力分析法,通过净压力与时间双对数曲线关系以及净上覆压力对数与净压力对数的关系可以有效判断煤层压裂裂缝形态,形成了双重诊断煤层压裂裂缝形态分析的新方法。According to the classic Nolte method,proposes the net pressure analysis method and the net overburden pressure analysis method.Base on the relationship between the lg-lg curve of net pressure and time,the relation between the logarithm of net pressure and the logarithm of net pressure can effectively judge the fracture morphology of the coal seam,and then form a new method for analyzing fracture morphology of fractured coal seam.

关 键 词：煤层压裂 净压力 净上覆压力 双重诊断 裂缝形态
