摘　　要：测井解释结果通常是制定单井压裂方案的静态参考资料,但是储层静态评价的准确与否影响相关方案的决策和评估。考虑多个测井参数对气井产能指示的综合影响,首先建立了表征储层产能大小的评价指标体系,然后根据大量现场数据建立了指标评价范围,采用模糊层次分析法综合各单因素评价结果对产能进行评价,实例表明基于测井参数的储层产能模糊综合评价方法在苏里格气田见到好的应用效果。Some results obtained from well-logging interpretation are often static references to formulate a fracturing scheme for an individual well. However, whether static evaluation for reservoir is correct or not may affect the decision and evaluation of many corresponding schemes. With reference to a comprehensive effect of some well-logging parameters on well deliverability indicator, we established an evaluation index system to characterize reservoir deliverability at first; then developed an evaluation scope based on a lot of in-situ data; at last adopted the analysis hierarchy process (AHP) to evaluate deliverability. Experiments indicate that a better application result can be obtained by this fuzzy evaluation of reservoir deliverability in Sulige gasfield.
