摘要: 辽河盆地是中新生代的弧后大陆裂谷,由四条基岩深断组成郯卢断裂系,其中二界沟茨榆坨东断裂是断裂系的主体。新生代断裂演化可以划分为三个序次,断裂的张裂期;裂谷的深陷期及裂谷的消止期。裂谷的序次控制了岩相带的分布和不同的油气藏类型。

Abstract: Based on the characteristics of faulting in the Liaohe rift valley, this article describes the evolution of faults and the distribution of oil traps and tectonic zones.Particular reference is made of the formation of oil and gas reservoirs in the fan-like graben and the sequential variations of the reservoirs related to the fault-block activity.
