| 摘 要： | 以高精度层序地层学理论为指导,通过对岩心、地震、测井、录井以及分析化验等资料的综合研究,建立松辽盆地肇源—太平川地区白垩系姚家组一段层序地层格架.将姚家组一段划分为3个层序,每一层序发育完整,分别由低位、水进和高位3个体系域构成；并在层序格架内进行沉积微相类型及沉积相展布特征研究,确定姚家组一段主要为浅水三角洲沉积体系,识别出三角洲平原、三角洲前缘、前三角洲3种亚相,以及分流河道、天然堤、决口扇、分流河道间、泛滥平原、水下分流河道、水下分流间湾、水下决口扇、河口坝、远砂坝和席状砂11种微相；三角洲平原、三角洲前缘广泛发育,前三角洲发育较差；三角洲平原分流河道通过填积和频繁的分叉改道,向湖盆中心方向长距离推进,在三角洲前缘的浅水区域发育了大量水下分流河道,分流河道与水下分流河道砂体相互切割、叠加,形成了树枝状砂体,(水下)分流河道砂体构成了油气富集的主要储集体.该区沉积相的精细研究为该区下一步油气的勘探与开发奠定了基础. |

| Abstract: | According to the theory of high-resolution sequence stratigraphy,the sequence stratigraphic framework in Member 1 of Yaojia Formation of Zhaoyuan-Taipingchuan area was built up through the comprehensive research on core,seismic,log and analysis assay.Member 1 of Yaojia Formation was divided into three completely-developed sequences which were constituted by three system tracts: low stand systems tract,transgressive systems tract and high stratigraphic framework were also discussed,confirming the shallow wat... |
