【摘要】 运用地震叠后及叠前裂缝检测技术对川西致密砂体的裂缝发育密度及方位进行了精细描述,分析了裂缝发育带的分布规律。由于裂缝的复杂性和多解性,单一地震技术难以对裂缝作出精确预测,需要结合叠后及叠前地震裂缝检测技术予以精细描述,这样既可以指示断裂发育部位,又能进一步揭示裂缝发育的规模及沟通情况。更多还原

【Abstract】 In this paper, both pre-stack and post-stack fracture detection technologies have been applied to a fine description to fracture ’ s growth density and azimuth of tight sandstone in western Sichuan Basin. And the distribution of fracture-developed zone is also analyzed. It is very difficult to predict fracture precisely by only one seismic technology just because of the complexity and multiple-solution of fracture. So, both pre-stack and post-stack fracture detection technologies should be applied together to the fine description, which can either indicate a fracture-developed portion or further show the fractured-developed scale and connectivity.更多还原
