R型因子分析和油气区带评价的多层系垂向叠合

R factor Analysis in Pertroleum Exploration Comprehensive Assessment

为了对参数之间相关性不好的样本总体进行评判，作者对因子分析得出的主成分进行模糊综合评判．并且引入空白值和标定值的概念，对多层系评判结果的垂向叠加作了探索．给出了下扬子地区苏北溱潼凹陷十四个区带单层系和多层系综合评判结果，最大程度地利用了详查阶段拥有的生储盖运圈保等油气地质资料，为开发阶段做好选区综合评价工作．

R factor analysis is widely used in reservoir analysis and chemical exploration. An atlempt was made to use this method to give a petroleum exporational comprehensive assessment, making use of the zero data, the indicate data, and the fuzzy comprehensive assessment method of main factor analysis. Three methods of comprehensive assessment are introdused to superpose the analysis results of multiple layers in perpendicular direction.
