摘要(Abstract)：

二连盆地通过 2 0多年的勘探 ,建设了一个年产原油 10 0× 10 4 t新的含油气区。同时 ,加深了对该区石油地质特征和油气分布规律的认识。二连盆地是由许多具有相似构造发育史的、分散的小型湖盆组成的盆地群。这些小型湖盆群具有独特的石油地质特征和油气成藏类型。根据二连盆地油气分布规律的认识 ,回过头来看东北亚地区裂谷盆地群如何进行油气勘探 ,提出了 4个勘探方向 :首先应选择坳陷背景上的、山前平原型的、沉积稳定型的、相对继承性发育的、大而深的单断断槽式凹陷进行油气勘探 ;单断断槽式、单断断阶式的凹陷以中央构造带作为油气勘探的突破口 ;单断断超式凹陷首选斜坡构造带上的鼻状构造 ;单断反转式凹陷要以勘探构造—岩性等复合型油气藏为重点。
Through more than 20 years of petroleum exploration, Erlian Basin has been constructed to a new petroliferous area with the production of 100×10 4 t/a. Meantime, petroleum geology characteristics and hydrocarbon distributive rules are known deeply. Erlian Basin is the basin group consisted of many similar structural developed history and small scattered lake basins. This small lake basin group has unique petroleum geology characteristics and hydrocarbon formed styles. Therefore, depending on hydrocarbon distributive rules in Erlian Basin, petroleum exploration orientations of rift basin group in area of Northeast Asia are presented:selecting depression background, mountain front plain, stable sedimentation, well-developed inherited features, and large and deep single-faulted trough sags;breakthrough gap is central structural belt in single-faulted trough terrace sags; nose structure of slope structural belt single-faulted overlap sags should be selected; lithology structure pools are important object in single-faulted reverse sags.
