摘　　要：本文针对四川碳酸盐岩裂缝气藏特点，应用三维地震资料对盆地内老气区隆昌—龙市镇地区进行了精细的构造、断层解释和含气裂缝发育带预测。设计钻探５口井均获气流，钻探成功率达１００％。此外，重新评价了１口干井，地震预测应产气，后经（酸化）测试获工业气流，收到理想效果。According to the features of fractured carbonate reservoir, this paper presents accurate structural interpretation and gas bearing fracture forecasting. Five wells are located with these data, and all of the wells have got gas after completion, and the ratio of successful drilling is up to 100% . In addition, one dry well is reevaluated and the results from seismic interpretation suggests this well should produce the gas. After the acidizing treatment, the well is turned to be a commercial gas well, and good results are obtained.
