摘　　要：东北含油气盆地Ｊ３－Ｋ１储层可以分为砂砾岩储层和特殊储居两大类，并以中、低孔低渗透为特征。砂砾岩储层主要发育于水下冲积扇和扇三角洲中。裂缝或裂隙、溶蚀孔洞是控制特殊储层物性，尤其是特殊储层渗滤能力的主要因素。水下冲积扇扇中亚相、扇三角洲前缘亚相、裂缝发育带。J3- K1reservoirs of the Northeastern oil-gas basins are divided into sand-conglomerate reservoirs and special reservoirs. They all have moderate/low porosi- ty and low permeability. The sand-conglomerate reservoirs are mainly developed in both subaqueous alluvial fan and the fan delta. Fractures or cracks and dissolved pores are main factors of controlling characteristics , especially permeability of special reservoir. The middle sandbody of underwater alluvial fan , the front sandbody of fan delta . the fracture developed belts , and the ancient weathering crust are beneficial exploration area of J3-K1 strata in Northeastern oil-gas basins.
