裂隙发育带是油气运移的基本通道之一。利用地震资料预测储层裂隙发育带可以应用以下 3种技术 :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构造属性分析技术 ;③叠前三维地震数据体的AVO及AVA分析技术。实践表明 ,利用多波多分量资料、叠前的AVO或AVA资料预测裂隙发育带效果会更好。尽管利用叠后资料研究裂隙发育带有较大的难度 ,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效果
Fissure development zone is one of the basic channels for hydrocarbon migration. There are three kinds of techniques that can be applied to predict fractured development zones of reservoirs by using seismic data: (1) post-stack 3D seismic data coherence analysis; (2) structural analysis of post-stack 3D seismic data; (3) AVO and AVA of prestack 3D seismic data analytical skills. Practice shows that prediction of fissure development zone using multi-wave and multi-component data, prestack AVO or AVA data will be better. Although the use of post-stack data to study the development of fissures with greater difficulty, but the high signal-to-noise ratio in the premise of full use of rich geological information containing three-dimensional data body, you can get satisfactory results
