超低渗油藏开发效果的多层次模糊综合评价模型

Multi-level Fuzzy Comprehensive Evaluation Model of Ultra-low Permeability Reservoir

从吉林油田超低渗油藏开发实例出发,对影响开发效果的指标进行相关性分析,优选出10个独立指标,进而通过模糊数学与1-9标度法建立了模糊综合评判数学模型,并且利用模糊层次分析方法得到各指标权重。对L16研究区块进行模糊评价,结果表明,该方法能够为现场开采提供理论依据,具有一定的客观性、准确性。

According to the developmental example of ultra-low permeability reservoir in Jilin oilfield, correlation analysis of the factors to affect development effect was carried out in order to optimize 10 independent indicators, and then a fuzzy comprehensive evaluation model was established based on fuzzy math and 1-9 scale method. And the weight of each index was got by fuzzy hierarchical analysis. At last, fitzzy evaluation of block L16 was carried out. The results show that this method can provide a theoretical basis for field development.
