摘　　要：在本文中,根据石油开发中的电法测井,我们提出并讨论了二阶自共轭椭圆型方程的一类等值面边值问题的极限性态,并根据实际中使用的电极系数据,采用固定的地层模型在计算机上进行了计算。In this paper, for the well-logging in petroleum exploitation we present and discuss the asymptotic behavior of solutions of a class of equivalued surface boundary-value problems for the second order self-conjugate elliptic equations. Furthermore, we take a fixed model of layer and compute with the data using in practice.
