针对裂缝性油气田已经成为今后油气勘探开发的主攻目标 ,尝试了利用地震资料识别和预测储层裂缝发育带的 4种方法技术 ,即 ( 1)叠后三维地震数据相干体分析技术 ;( 2 )叠后三维地震数据体沿层构造属性分析技术 ;( 3)叠后三维地震数据体目标层介质平均吸收参数分析技术 ;( 4 )叠前三维地震数据体的AVO及AVA分析技术。实践表明 ,利用地震资料研究储层裂缝及其发育带确实有较大的难度 ,但在资料信噪比较高的前提下 ,充分利用包含着丰富地质信息的三维数据体可以得到令人满意的地质效果 In view of the fact that fractured oil and gas fields have become the main targets of future exploration and development of oil and gas, four methods of seismic data identification and prediction of fracture development zones are tried and tested: (1) post-stack 3D seismic data coherence tomography; (2) Post-stack 3D seismic data along the layer structure attribute analysis technology; (3) post-stack three-dimensional seismic data target layer medium average absorption parameter analysis technology; (4) prestack 3D seismic data body AVO and AVA analysis techniques. Practice shows that using seismic data to study reservoir fractures and development zones is indeed more difficult. However, under the premise of high signal-to-noise ratio, it is feasible to make full use of three-dimensional data volumes containing abundant geological information Geological effects
