曲流河油藏地震正演模拟分析
|
摘要
通过建立曲流河地质模型,再进行油藏数值模拟获得油藏各开采阶段的岩石物理模型,然后进行岩石物理计算得到地震参数,最后利用地震正演模拟合成地震记录。从合成地震记录中可以分析由曲流河点坝砂体中的侧积泥岩引起的地震响应异常,还可以分析由侧积泥岩形成的剩余油产生的地震响应。
This paper discussed the different steps involved in forward modeling.First,a geological model of meandering river was built.Second,the rock physics models of different exploitation stages were modeled through reservoir numerical simulation.Third,seismic properties were calculated from the rock physical model.Finally,synthetic seismogram was built through seismic forward modeling.We investigated the seismic responses of laterally-accreted mudstone of point bar in the meandering river and the seismic responses of residual oil in the laterally-accreted mudstone.
