摘要
The surface-to-borehole electromagnetic technology is a method with great potential for detecting residual oil gas. Walkaway vertical electromagnetic profile of surface-to-borehole was put forward. In this paper some rules of dynamic reservoir process are drawn by modeling surface walkaway power supply and changing conductivity, size, depth and distance from receive well of model using 3D integral equation forward code. 3D modeling comparison between homogeneous background and layered medium shows that it has wider detection range and more accurate, which can effectively monitor the dynamic oil gas process. The simulation study suggests practical application of walkaway vertical electromagnetic profile method for reservoir exploration as a new approach.
