摘　　要：本文利用时域有限差分法(FDTD)模拟常规双感应—八侧向组合测井仪在大斜度井、水平井中的电磁响应,通过XFDTD软件的模拟,指出地层各向异性、井斜角等对感应测井电磁响应的影响关系。这项模拟为常规感应测井在大斜度井、水平井中电阻率响应校正提供了一种新思路。Simulation of the logging response with combination of dual-inductionand and eight side direction logging tool in highly deviated wells uses time domain finite difference(FDTD).Through XFDTD software the effect of anisotropy of the formation and hole deviation angle on induction logging electromagnetical response is pointed.The simulating has provided a new idea for resistivity response correction of conventional induction logging in highly deviated and horizontal wells.
