摘要
According to the results of 2-D resistivity inversion of magnetotelluric sounding,geological structures and strata were preliminarily confirmed.By synthetic analysis of petrophysical characteristics,the authors established the petrophysical parameters of strata and rocks in the study area,established the initial model of geology-geophysics,carried out gravity-magnetic-magnetotelluric joint inversion under the restraint of geological,well log and seismic data,and constantly revised the model of geology-geophysics and the results of 2-D resistivity inversion of magnetotelluric sounding,to make the gravity-magnetic measurement data fit in with the theoretical calculations.The results of interpretation of geological structures and strata in Yin’e basin show that the gravity-magnetic-magnetotelluric joint inversion can effectively overcome the multi-resolution of the single one,more correctly identify strata,and greatly improve the accuracy of quantitative interpretation.
