裂缝发育带的地震地质综合预测方法

本文讨论了一种综合应用岩相，测井相和地震相分析手段研究和预测裂缝性储集层的方法，并将其用于川南丹凤场阳新统裂缝系统的研究。提出本区阳三储层裂缝发育带主要分布于脆性的硅质灰岩相段附近，其地震响应表现为低速连续强振幅相，预测结果与钻井资料的对比表明，此方法可较好地预测裂缝发育带的展布和有效地识别解释陷阱。

A COMPREHENSIVE RESEARCH OF SEISMOGEOLOGY FOR FRACTURE RESERVOIR

A comprehensive research method is discussed for fracture reservoir which including analysis of lithofacies, electrofacies and seismic factes. As an example, it is applied to study Yangxin series (Lower Permian ) in Danfengchang, Southern Sichuan.The result shows that the facture reservoir is distributed mainly with the siliceous limestone and its seismic response is lowspeed, high amplitude,continous seismic factes. The coincidence of prediction with drilling data indicate the effectiveness of the method in prediction of distribution of fracture reservoir and recognition of interpreted pitfalls.
