【Abstract】 Oil and gas exploration and survey with seven radioactive methods were conductedin an area of 150 km2 in central Sichuan and, as a result, 1902 data were obtained. UsingR-mode factor analysis, the authors studied five methods, seven indices and 1176 data. Theresults of the study show that factor analysis can provide combinational information fordelineating oil and gas anomalies, reduce interference, make prominent anomalies, and pointout prospect area for further oil and gas exploration in the study district.更多还原
