With 1:50 000 high precision gravity,magnetic and magnetotelluric sounding,the authors measured the Sinian-Lower Paleozoic marine strata on the west side of the Xuefeng Mountain.Combined with the characteristics of drill hole,geological data and physical property statistics,the authors made positive and negative interpretations on the acquired gravitational,magnetic and electrical data,thus interpreting the fracture structure and strata spatial distribution characteristics,explaining the distribution of strata,buried depth and thickness and predicting the favorable oil and gas reservoir structural belt.The results show that,with the disturbance of complex geological settings,human activities and industries,the integrated gravitational,magnetic and electrical geophysical methods can maximally reduce the uncertainty of geological interpretation and accurately identify the distribution,fold,fault and local structure of Sinian-Lower Paleozoic marine strata in this area,and thus can play a vital role in oil and gas prospect evaluation.
