四维瞬变电磁法油藏监测正演模拟

Forward Modeling Simulation of Four-dimensional Transient Electromagnetic Reservoir Monitoring

本文采用基于张量格林函数的体积分方程法进行四维模型瞬变电磁响应的正演研究,文章中首先说明了四维瞬变电磁法模拟的可行性及程序实现,然后分别设计了两个三维异常体模型(水藏、油藏),采用两种观测方式(激发与接收平行、激发与接收垂直)进行正演模拟计算,并对所得的二次总场的数据进行了分析。

In this text we used the method of volume integral equation base on tensor Green＇s function to study the forward of 4D transient electromagnetic response. At first this text explain that 4D transient electromagnetic is feasible to simulate and actualize by procedure,then we differently devised two 3D unconventionality model（water ,oil）,we adopt two observational way to process forward simulation account, and then we analyse all secondary general field data we got.
