摘要
松辽外围东部盆地群位于中国东北地区的东部,研究区内共有39个中小规模沉积盆地,总面积约52×10~4km~2.在总结东部盆地群烃源岩沉积特征的基础上,通过对三江、勃利、通化及红庙子等盆地下白垩统烃源岩有机地球化学综合分析,查明了研究区下白垩统主力烃源岩有机质丰度、有机质成熟度以及有机质类型等指标特征、分布规律,并分析了影响这些指标在区域上规律变化的地质因素,以提升研究区的油气基础地质认识,为东北地区油气资源调查与勘探部署提供科学依据.
The eastern basin group in the periphery of Songliao Basin,located in the east of Northeast China,includes39 small-and medium-scale sedimentary basins,covering an area about 52×10~4 km~2.Based on the sedimentary characteristics of source rocks in the eastern basin group,through comprehensive analysis of organic geochemistry of the Lower Cretaceous source rocks in Sanjiang,Boli,Tonghua and Hongmiaozi basins,the paper identifies the characteristics and distribution rule of organic matter abundance,maturity and types in the Lower Cretaceous source rocks of the study area,and analyzes the geological factors that affect regular changes of the above indexes regionally,to improve the basic geological understanding of oil-gas resources in the area and provide scientific basis for the oil-gas survey and exploration in Northeast China.
