摘要
通过对晋城地区200余口压裂井的施工曲线进行统计,经过整理、分类、判别,并结合地面试验结果,研究出不同类型的曲线所对应的煤层压裂裂缝展布情况,制定出不同人工裂缝延伸展布典型的标准曲线,可判别压裂施工效果;利用压裂施工监测曲线形态及压后排液产气情况,对压后压裂效果进行了分析评价。该方法经100多井次验证,符合率大于70%。
According to statistics on operation curves from more than 200 fractured wells at Jincheng area,by sorting,classification,discrimination and combined with the results of ground test,the different types of curves corresponding to fracture the coal seam distribution case are worked out.Different artificial Crack extension of the standard curve of the typical distribution,which can distinguish fracturing effect,is developed.By using monitoring curve shape of fracturing and flowing and gas production situation after fracture,fracturing effect after fractured is analyzed and evaluated.The method is verified by more than 100 wells,and compliance rate is more than 70%.
