摘　　要：对川中某地１５０ｋｍ２范围进行了七种放射性方法的油气勘查测量，取得了１９０２个测量数据。利用Ｒ型因子分析对其中的五种方法、七项指标、１１７６个数据进行了研究。研究结果表明，因子分析能够提供圈定油气异常的组合信息，降低干扰、突出异常；为研究区今后的油气勘探指出远景区。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.
