| 摘 要： | 基于构造层序分析方法，应用三维地震、测井、岩心资料对辽河西部凹陷古近系做了层序地层研究和地层岩性油气藏预测。古近系作为一个超层序组可以划分出4个超层序8个三级层序。根据同沉积构造坡折类型，可以把层序划分为同沉积断裂坡折层序、同沉积挠曲坡折层序和无坡折的缓坡层序三种层序类型。其中同沉积断裂坡折层序主要发育在超层序1、超层序2和超层序3，同沉积挠曲坡折层序和缓坡层序主要发育在超层序4。超层序2和超层序3由同沉积构造坡折控制的层序低位域和高位域砂体与湖扩展体系域优质烃源岩配置，成藏条件优越。同时这些岩性圈闭一般处于中深层次生孔隙发育带内，储层性能良好，最有利于岩性油气藏发育。据此在辽河西部凹陷提出了西斜坡锦1断层的下降盘，双台子断裂下降盘；东部陡坡台安—小洼—海外河断裂下降盘是岩性油气藏发育的有利部位。〖JP〗

| Abstract: | Based on tectonic-sequence analysis method and using 3D seismic data, log curves, and cores, Eogene sequence stratigraphy and stratigraphic and lithologic reservoirs prediction are studied in this paper on Liaohe West Depression. One super sequence set, four super sequences and eight sequences are identified in Liaohe West Depression Eogene. Based on syndepositional structural slope-break types, developed in Liaohe West Depression Eogene, sequences can be divided into syndepositional fault slope-break seque... |
