摘　　要：影响碳酸盐岩储层的因素较多，并且这些因素之间往往具有错综复杂关联性。以川中磨溪地区嘉陵江组嘉二段为例，采用改进AHP法确定各评价因素的权重系数，可以解决传统AHP法存在的弊端。应用模糊综合评判法对储层质量进行定量评价，解决了储层评价因素问的关联性和“不确定性”问题。其评价结果与油气实际产能具有很好的一致性，表明运用改进AHP法结合模糊综合评判进行储层定量评价是切实有效的，对研究区气田的勘探和调整挖潜具有一定的意义。For the numerous factors impacting the carbonate reservoir and the complex correlations between them, taking Member Jia-2 of Jialingjiang Formation in Moxi in central Sichuan as an example, an improved AHP method is adopted to determine the weighting factor of evaluation parameters in this paper, so as to solve the drawbacks of traditional AHP method. With the application of fuzzy comprehensive evaluation method for quantitative evaluation of reservoir quality, the correlation between evaluation parameters and the uncertainty are resolved. Evaluation result has a good consistency with the actual production of oil and gas, indicating that the improved AHP method combined with fuzzy comprehensive evaluation is effective on quantitative evaluation of reservoir, cance for exploration and development adjustment of gas field in the studied area.
