| 摘 要： | 本文证明了在分区均匀的介质中,电测井的Green函数是各区电导率的解析函数,并给出了它的Taylor展开式。如果背景值选择得适当,这个展开式是收敛的。

| Abstract: | The Green's function in a medium in which the conductivity varies stepwisely across boundaries and keeps constant elsewhere is an analytic function of the conductivities of different regions.In this paper the Taylor's expansion of the Green's function is given.By sui-tablly choosing the point around.which the function is expanded,the convergency of the series is guaranteed. |

| Keywords: | Electric logging Piecewise homogeneous medium Green's function Taylor's expansion |
