摘　　要：单井最终可采储层(Estimated Ultimate Reserve,EUR)评价是致密油气藏动态分析的重要工作,对气井合理产量制定、井网的部署和调整具有重要意义。在现有单井EUR评价方法适用性分析的基础上,筛选出了适用于致密砂岩气藏压裂井EUR评价方法。基于苏东南区实例井分析了不同方法在气井不同生产阶段的适用性。研究结果表明:苏东南区致密砂岩气藏单井EUR评价时,生产早期推荐产量不稳定分析法,生产中期推荐产量不稳定分析法、物质平衡法,生产后期推荐产量不稳定分析法、产量递减分析法。The Estimated Ultimate Reserve(EUR)evaluation is an important work in the dynamic a-nalysis of tight oil and gas reservoirs.It is of great significance for reasonable work system,well pattern arrangement and adjustment.Based on the applicability analysis of the existing EUR evaluation methods,three EUR evaluation methods are recommended for fractured wells in tight sandstone gas reservoir.The applicability of different methods in different production stages of gas well is analyzed based on a case well in southeast Jiangsu Province.The results show that present production decline method is recommended in early production,present production decline method and material balance method are recommended in middle production,present production decline method and traditional production decline method are rec-ommended in later period of production.
