总结了川南长垣坝地区寻找碳酸盐岩裂缝型气藏的经验，归纳了该区的基本地质特征。利用图像分析技术预测了有利储集带，利用构造滤波、古构造应力预测了有利裂缝发育的褶曲区块，利用古、今断层应力预测了有利于裂缝发育的断层区块，利用地震剖面圈定了地震异常指示的裂缝发育带。将上述方法综合应用，预测了该区碳酸盐岩裂缝圈闭的有利裂缝发育区和油气聚集带，进而划分出４２个有利圈闭，提供了下步钻探目标。
This paper summarizes the experience of searching for carbonate fractured gas reservoirs in Changyuanba area, southern Sichuan, and summarizes the basic geological features of this area. The favorable reservoir zone is forecasted by using the image analysis technique, the folded zone with favorable fractures is forecasted by structural filtering and palaeotectonic stress, the faulted zone is predicted by the ancient and present fault stresses, and the seismic profile is used to determine Seismic anomalies indicate fracture development zones. The above method is applied comprehensively to predict favorable fracture development zones and hydrocarbon accumulation zones in carbonate fractures in the area, and then to divide 42 favorable traps to provide the next drilling target.
