层次分析法在碳酸盐岩储层定量评价中的应用

用于碳酸盐岩储层定量评价的因素较多，进行定量评价时，如何应用这些因素以分析各因素之间的关系特征显得尤其重要。研究发现，评价因素之间具有一定的层次特征,可以用层次分析方法来定量确定各因素对于储层定量分类的相对重要性定量指标(权重系数),结合模糊综合评判法可对储层进行定量评价。对川中磨溪地区嘉陵江组嘉二段各小层储层评价的结果表明,用层次分析方法(结合模糊综合评判法) 进行储层定量评价的结果和实际储层产能基本一致，取得了良好效果。

Application of Hierarchic Analysis to Quantitative Evaluation of Carbonate Reservoir

Quantitative evaluation for carbonate reservoir can improve the accuracy and correction of reservoir evaluation. The factors that are used in quantitatively evaluating carbonate reservoir are too more, so it is quite important to know how to use these factors and their relationships. Research finds the factors have some typical hierarchic properties, and therefore hierarchic analysis method can be used as important quantitative indexes. Combined with fuzzy comprehensive evaluation, it can be used to evaluate reservoir quantitatively. A quantitative evaluation example for every members of the Jia-2 member in the Jialing River formation in Moxi area which is situated in central Sichuan suggests that the calculating result is accordance with the actual result, in another word, hierarchic analysis method is effective.
