| 摘 要： | 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

| Abstract: | The fractured reservoir is the basic passageway of oil and gas. When using seismic data to forecast fracture extension zone of reservoir, the following three methods can be applied: (1) coherence cube analysis of the stacked 3|D seismic data; (2)horizontal structure attribute analysis of the stacked 3|D seismic data cube; and (3) AVO and AVA analyses of pre|stack 3|D seismic data. The practical application shows that although it is difficult to study reservoir fracture and its extension zone by using seismic data, it is satisfying to take full advantage of 3|D data cube including plenty of geologic information under the condition of high S/N ratio. |
