摘要(Abstract)：

综合应用岩心、录井、测井、地震等资料,在地震剖面追踪和连井剖面对比的基础上,通过井震结合分析将海拉尔盆地呼南地区的南屯组一、二段细分为5个旋回,并对每个旋回的沉积特征和沉积相进行了对比分析。认为呼南地区南屯组一段地层以冲积平原、扇三角洲和滨浅湖相为主,南二段以扇三角洲、辫状河三角洲、滨浅湖相及沼泽相为主;南二段发育多个煤层,和暗色泥岩交互分布,构成煤系烃源岩;南二段上部2个旋回的三角洲前缘储层物性相对较好。
Comprehensively integrating the core samples,mud and well loggings and seismic data and so on,on the basis of the seismic cross-sections tracing and well-connected section contrast,No.1 and No.2 Members(i.e.K_1n_1 and K_1n_2) are further classified into five cycles for Nantun Formation in Hunan area of Hailar Basin with the help of well-seismic connected analysis.At the same time,the sedimentary characteristics and facieses are contrasted and analyzed for each cycle.The study shows that Member K_1n_1 takes alluvial plain,fan delta and shore-shallow lacustrine facies as the primary forms while Member K_1n_2 indicates fan delta,braided river delta,shore shallow-lacustrine facies and swamp facies as main types;many coal beds are well developed in the latter and alternately distributed with dark mudstone,finally coal-measure hydrocarbon source rock is generated;the physical properties are much better for the reservoirs in the delta front of two cycles on the top of Member K_1n_2.
