双频三极激电测深数据处理方法研究

THE RESEARCH FOR DUAL BAND POLE-DEPOLE IP SOUNDING DATA PROCESS

目前三极装置的频率域激电测深工作后期数据处理是一大难题。国内对此方法成熟的反演软件较少,大多数只能进行一维反演,这限制了此方法在国内的应用。国外的二维带地形反演软件RES2DINV支持多种电极排列方式,可进行时间域和频率域激电反演,并可做地形校正,是比较实用的软件;由于V8工作站具有多道测量的优势,具有更高的工作效率,这里通过研究V8工作站采集所得的双频三级数据格式,编写程序将V8数据格式转化为RES2DINV软件可以识别的格式,从而实现了三极激电测深的带地形的二维反演。

At present,the data-processing of pole-dipole device in frequency domain IP sounding is a difficulty problem.The mature inversion software in domestic are fewer,most software only uses one dimensional inversion which limits the application of this method in domestic.The 2D inversion software RES2DINV is a practical software,because this software support multiple electrode arrangement,it can do inversion in time domain and frequency domain,and it can also do terrain correction.Because V8 workstation can achieve multi-channel measurement with higher work efficiency,this paper studies V8 data format,writes a program to change V8 data format into the format that RES2DINV software can identified,thus realize the dual band pole-dipole IP sounding 2D inversion with terrain.
