中文摘要	利用岩心、测井和地震等资料对海塔盆地塔南凹陷下白垩统南屯组一段(K_1n_1)层序格架和沉积体系进行研究。结果表明,K_1n_1内部可以识别出3个不整合面和2个湖泛面,最终将其划分为3个三级层序;K_1n_1主要发育扇三角洲、湖底扇和湖泊3种相类型,南一段下亚段(K_1n_1~L)与南一段中亚段(K_1n_1~m)沉积时期受盆地初始裂陷期影响,主要发育西部缓坡物源控制下的长轴扇三角洲沉积体系;南一段上亚段(K_1n_1~u)沉积时期受盆地强裂陷期影响,主要发育湖泊沉积体系,此时盆内次级控陷断层受拉张作用发生翘倾而形成大规模反向断层。源储互层的生储组合特征、反向断层下盘的构造高部位、翘-储形成的扇三角洲前缘优质储层和断-壳-扇组成的油气优势输导通道共同决定了研究区西部次级凹陷中洼槽反向断层下盘为油气富集区。
英文摘要	Core,drilling and seismic data were used to study the sequence framework and depositional system of K_1n_1 member in Tanan Depression of Haita Basin. The study results indicated that three unconformity surfaces arid two lacustrine overflow surfaces could be identified within K_1n_1,it was eventually divided into three third-order sequences; it was defined that three kinds of facies type, such as fan delta, sublacustrine fan and lake were mainly developed there; K_1n_1~L and K_1n_1~m were affected by initial chasmic stage in the basin,a long-axis fan delta depositional system controlled by western gentle slope source was mainly developed in the area. K_1n_1~L is affected by intensive chasmic stage of the basin, where lacustrine sedimentary system is mainly developed, at this time, sub-depression-controlled faults in the basin are suffered from tension and upward development and large-scale antithetic faults are formed, assemblage characteristics of source-reservoir interbeds, the high structural location of the antithetic fault footwall, "warp-reserves" created quality reservoir of fan delta front and "fault-crust-fan" formed dominant transportation pathway determine that western secondary and lower antithetic fault footwall are the major areas of hydrocarbon accumulation.
