摘要

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。
he bole geological characteristics of the ftactured ac reservoirs of carbonate rock in Changyuanba Area in South Sichuan and the experiences of surveying the gas reservoirs are summarized.The favourable reservoirs are predicted by image analysis technique.The fold tracts favourable for fracture growth arc predicted by structure filtering and palaeostructure stress. The fault tracts favourable for fracture growth are predcted by palaeo-present fault stress.The fracture growth belts indicated by seismic anomaly are divided by seismic section visual scanning. Through comprehensively using the above techniques,the favourable fracture growth districts and oil-gas gathering belts of carbonate rock fractural trape in the area are predictal,thus dividing 42 favourable trape to provide the drilling targets.
