激发极化法测深曲线解释中的快速反演法

RAPID INVERSION METHOD IN THE INTERPRETATION OF IP SOUNDING CURVES

本文根据“直流电阻率测深曲线解释中的直接反演法”一文，利用塞格尔的极化率模型，首先给出了在激发极化法测深曲线解释中的直接反演方法。在此基础上，又结合Ｏｌｄｅｎｂｕｒｇ，Ｚｏｈｄｙ等人的工作，使用对比迭代反演方法来提高反演精度。文章对几条理论测深曲线进行反演检验，结果表明效果很好。

Based on the published paper of present anthor (Ruan & Xu,1996) and Siegel's model of polarizability,this paper first derives a direct inversion method for interpretation of IP sounding curves.Then according to the works of Zohdy (1989) and Oldenburg(1991),a contrast iterated inversion method in the interpretation of IP sounding curves was presented to improve the inversion precision.The interpretation for the given IP sounding data shows that these methods are excellent.
