The research and application of equivalent source inversion and imaging in induced polarization method
摘要
Abstract
In the process of geophysical data processing and interpretation,inversion multiple solution greatly increases the difficulty of interpretation and seriously affect the reliability and accuracy of the results.Reliability not only means the degree of the "fit" between theoretical anomaly and observed anomaly,but also consider the"consistent"of the model body with the ac-tual geological body.How to meet the above requirements and reduce multiple solutions to improve the accuracy of the process-ing and interpretation becomes one of the main factors to choose the inversion methods.Currently,the equivalent source inver-sion imaging theory in gravity and magnetic fields has made some progress.In order to prove that the method in the time do-main induced polarization method is also applicable,I designed three impedance sphere models,and based on the theoretical a-nomaly values to do inversion imaging.Then,combined with the actual data,I carried on the calculation and processing.We can roughly determine the spatial location,the size and the shape of the source body.It proved the credibility and accuracy of the method from the theory and practical application.关键词
