【摘要】 为了揭示缝洞储层的地震波场特征,运用适合任意倾角且横纵向可变速的波场数值模拟方法(相移加插值)研究了其中一种重要的具有"串珠"状反射特征的地质模型。根据某地区地质特征设计了四个模型,并利用相移加插值的方法对模型进行了正演和偏移,得出了含溶洞介质的地震波场特征的一些有意义的结论和认识。更多还原

【Abstract】 To reveal the wavefield characters of fracture reservoir, we use the PSPI method which fits to the changes of the medium velocity and layer dip angle on the horizontal and vertical orientation to find out the characters of the reflection with bead-shaped structure. The operator is then used in the forward modeling and migrations of the four models built based on the geological features of the area. Some useful conclusions are drawn from the numerical simulation results of the models.更多还原
