摘　　要：二连油田阿尔凹陷一般为中低孔隙度、渗透率储层,常规测井解释对储层分类及产能评价受到限制。实际生产中常规测井解释对储层的评价只是定性分析,以数字岩心技术的核磁共振岩样分析为基础,系统分析T2谱,获取岩石的孔隙度、渗透率、含油饱和度、束缚水饱和度、孔隙度结构指数及孔隙度尺寸在总孔隙度中的百分含量S1、S2、S3,评价岩样的孔隙结构类型及储层类型,从而对储层产能进行评价;结合含油饱和度参数对储层流体性质进行判断。该方法在二连油田阿尔凹陷取得了很好的应用效果。： Aer Sag is characterized by middle-low-porosity, middle-low-permeability in Erlian oil- field, so, reservoir classification and productivity evaluation are limited by conventional log inter- pretation. In log practice, conventional log interpretation is only used to qualitatively evaluate the reservoir. According to NMR core analysis, based on digital core technology, obtained are permeability, porosity, oil saturation ratio, water saturation ratio, pore structure index,S1,S2 and S3 of rock by analyzing T2 distributions. Then, evaluated are core pore structure types, reservoir types and productivity. Combining with oil saturation parameters, the reservoir fluid properties can be determined. The digital core technology has better log application effects in Aer Sag of Erlian oilfield.
