中深部矿产资源勘探井中阵列激电方法研究
Research on borehole array induced polarization method for middle-deep mineral resources exploration
摘要
Abstract
The induced polarization method has many characteristics,such as observation parameters,flexible observation device,and sensitive response to mineral resources,and is particularly advantageous in the exploration of mineral resources in the middle and deep areas.This paper conducts a systematic and in-depth study on the observation method,forward and in-version theory and method of the IP in the well.Firstly,two kinds of observation arrays of IP methods in the well are de-signed.Then,the theoretical formula of 2.5-d finite element forward modeling for the induced polarization method based on a continuous medium model is derived,and the linear equation of joint constraint inversion of resistivity and induced polarization data acquired in the well is given.Finally,through the inversion calculation of the complex geoelectric model and the experi-mental data of the flume,the feasibility of the well-inducing method in the middle and deep mineral resources is verified.关键词
