基于AHP的储层非均质性综合评价研究

运用层次分析法(AHP)对葡108区块重点砂体的储层非均质性进行综合评判,建立系统层次结构模型,利用相关性分析原则优选评判参数,并根据专家打分法和标度原则对储层的各个指标进行科学排序,计算权重指标。将计算得出的非均质性综合指数和砂体对应的采出程度进行趋势分析,得出非均质综合指数越高,采出程度越小,挖潜潜力越大,对该区块挖潜对象的确定以及挖潜方案的优选有重要的意义。

Study on the Comprehensive Evaluation of Reservoir Heterogeneity Based on AHP

The analytic hierarchy process (AHP) was used to comprehensively evaluate the reservoir heterogeneity of the key sand bodies in P108 block, the hierarchical structure model of the system was established, and the parameters were optimized by the correlation analysis principle. The indexes of the reservoir were sorted according to the expert scoring method and the scale principle, and the weight index was calculated. The heterogeneity index and the recovery degree of the sand body were analyzed. It's concluded that, the higher the heterogeneity index is, the smaller the recovery degree is, and the greater the potential tapping potential is. The conclusion is of great significance to determine the object for tapping potential of the block and to optimize the potential tapping scheme.
