摘要
系统地介绍了井间电磁波数值模拟与成像方法的研究现状。正演方面主要讨论了有限差分、有限元和积分方程法,分析了各种方法的优缺点、适用范围,并指出了未来发展趋势;反演方面主要讨论了线性反演和非线性反演,根据井间电磁波成像的性质,对时间域和频率域线性反演方法分别做了详细论述,并给出了未来发展趋势。
This paper deals with the present research situation of the numerical simulation and imaging technology for crosshole electromagnetic wave. In the forward aspect, the advantages and disadvantages of such methods as finite difference, finite element and integral equation as well as their development trend are discussed. In the inversion aspect, mainly linear and nonlinear inversions are analyzed, with a detailed discussion on the linear inversion methods both in the time domain and in the frequency domain as well as a prediction of their future development trend.
