Simplified analysis of fracture treating pressure and fracture morphology in coalbed gas well

摘要: 根据煤层气试验井的施工资料, 分析了煤层压裂施工压力的特点以及井深、R_o与破压梯度的关系, 并根据裂缝监测 (测井温法、大地电位法和微地震法) 测量的裂缝方位和缝高, 对煤层压裂形成的裂缝特点进行了分类和总结, 提出了指导性的建议。

Abstract: Based on experiences of previous treatment data of coalbed gas test wells,the featrues of fracture treating pressure in coal seams and the relationship between the depth,R_o and fracture pressure gradient are analyzed.The fracture features after fracturing operation are also classified and summarized,according to fracture orientation and height recorded by fracture monitoring(temperature logging,ground potential and uphole survey).Based on that some useful suggestion and valuable reference for the future fracturing in coalbed gas wells are provided.
