摘要
本文用本征函数展开法系统地讨论了电阻率测井法中的Green函数问题。所考虑的三种情形是:1.均质地层;2.带井眼的均质地层;3.带均质地层和侵入带的井眼。
Green's function in electrical resistivity logging is systematically discussed witheigenfunction expansion method. The threc situations considered are:① a homogeneousmedium; ② cylindrical two-layer medium (borehloe and formation); ③ cylindricalthree-layer medium (borehole, invaded zone and formation).
