| 摘 要： | 二连裂谷系由５０多个相互独立的，具有相似沉积发育史和构造演化史的地堑，半地堑组成，它们自成独立的含油气系统。由于构成含油气系统的地质要素发育不同，地质作用及其地质要素与地质作用的时空配置关系的差异决定了各个含油气系统中油气富集程度的极大差异；但含油气系统中油气分布具有相似性。临近深洼槽的缓坡挠曲带是油气聚集的最有利场所。

| Abstract: | Erlian rift consists of over fifty garbens and half-garbens, each of them has similar sedimentary development and structural evolution, and formed independent petroleum system. Because of different development of geological agents, events and their space-time matched relationship in every petroleum system, the enrichment of oil and gas in these systems is quite different to each other. But distribution of petroleum is similar in every petroleum system, the oil and gas enrichment is much different,the bending fiexcure of backlimb which is adjacent to source sag is the most favorable place for oil and gas accumulation. |
