摘　　要：随着裂缝性油气藏数量和储量越来越多被发现,裂缝型油气藏近年来已然成为全球探索油气资源的重要区域。裂缝作为油气储集空间和运移通道,对油气最终的产能有重要的影响。基于此,对裂缝因子属性、倾角属性、曲率属性、相干属性以及方差属性等进行了阐述,并将多种叠后地震属性裂缝预测方法应用于四川盆地蓬莱区块,对比这几种叠后地震属性结果,对裂缝有一定的预测效果。With the increasing number and reserves of fractured oil and gas reservoirs being discovered,fractured oil and gas reservoirs have become an important area for global exploration of oil and gas resources in recent years.Cracks,as oil and gas storage spaces and migration pathways,have a significant impact on the ultimate productivity of oil and gas.The article mainly elaborates on the fracture factor attribute,dip angle attribute,curvature attribute,coherence attribute,and variance attribute.Finally,various post stack seismic attribute fracture prediction methods are applied to the Penglai block in the Sichuan Basin,and the results of these post stack seismic attributes are compared to show certain predictive effects on fractures.
