摘　　要：鄂尔多斯盆地北部塔巴庙区块盒3段致密砂岩储层物性差,孔隙结构复杂,表现出较强的非均质性,气层产能差异较大。基于岩心分析、测试资料,采用测井参数交会法对气层加以识别,并根据产能情况对气层分级。通过对比分析不同产能气层储层特征,明确了盒3段砂岩气层产能差异特征及高产控制因素,并建立了气层产能评价标准。研究表明,盒3段气层产能差异综合受到岩性、沉积相、油气充注等因素影响,其中,曲流河道主体、决口水道中心线附近砂体等有利储集相带以及储层内部非均质性是影响含气砂岩产能的重要因素。H3 tight sandstone reservoir of Tabamiao block in the northern Ordos basin is characterized with poor physical condition,complex pore structure and strong heterogeneity, consequently, the productivity among wells is different significantly. Based on core analysis data and testing data, the gas layer is identified by the way of well-logging parameter intersection method. The producing layers are classified according to the productivity. By comparing the different productivity characteristics of gas layers, the production difference characteristics and high production controlling factor of H3 sandstone gas layer, meanwhile, the gas production capacity evaluation standard is established. The research shows that the difference of production is affected by the factors such as lithology,sedimentary facies and hydrocarbon charging. Among them, the favorable reservoir facies such as the main body of the meandering river and the sand body near the center line of the crevasse channel are the key factors. So is the heterogeneity inside the reservoir.
