摘　　要：黑龙江省东北部三江、虎林、勃利、鸡西、双鸭山、双桦等盆地与桦南隆起的关系对本区油气资源的勘探开发有重要的意义。从区域地层对比、海相古生物化石、盆地边界断裂以及地球物理MT剖面等方面对其进行了探讨,揭示黑龙江省东北部盆地群具有相同的演化历史,在城子河、穆棱期由东向西共同遭受海侵事件,现今盆地南界均为破坏性逆冲断层,综合认为各盆地在城子河、穆棱期为一统一的大陆边缘近海盆地——三江—穆棱盆地,桦南隆起尚未隆升。结合猴石沟组的古水流向、砂岩的物源区分析及砾岩砾石成分统计认为,桦南隆起应于东山组沉积期后隆升,并在猴石沟组沉积期已隆升一定高度,为周缘盆地提供物源,形成现今黑龙江省东北部地区的"盆岭格局"。The relationships between Huanan uplift and its surrounding basins, such as Sanjiang Basin, Hulin Basin, Boli Basin, Jixi Basin, Shuangyashan Basin and Shuanghua Basin,are playing an important role in the regional oil and gas resources exploration and development. The researches of regional stratigraphic correlation, marine fossils, basin boundary faults and geophysical MT profile suggest that these basins experienced the same evolution, and underwent one or more transgressions during Chengzihe and Muling Formations. The present basin boundary thrust faults and geophysical MT profiles crossing the basins and Huanan uplift show that the present isolated basins belonged to a large-scale epicontinental offshore basin （Sanjiang - Muling Basin） during the period of Chengzihe and Muling Formations. Meanwhile, the Huanan uplift did not develop. Base on the directions of paleocurrent, sandstone provenance analysis and gravel composition statistics, it reveals that Huanan uplift were uplifted after the depositing of Dongshan Formation, and supplied the sediments for the surrounding basins during the period of Houshigou Formation, and the present basin-range topography appeared in the northeastern Heilongjiang Province.
