| 摘 要： | 松辽盆地早期断陷湖盆样式研究表明，松辽盆地存在二型四式的构造样式：即有补偿断层和无补偿断层的单断型断陷盆地，有补偿断层和无补偿断层的复合型断陷盆地。一个完整的断陷湖盆层序形成一套区域生储盖组合，其中，发育在TST和HST之间的最大密集段为主力生油层，也是良好的盖层，而LST，TST底部，HST顶部及RST通常发育有利储层。它们的规律性配置可构成上生下储，下生上储，侧生侧储和自生自储四种有利的生储盖层组合类型。每个体系域中都有岩性油气藏，构造油气藏是HST的主要类型，RST中可以找到不整合油气藏。

| Abstract: | The early stage fault depression of lacustrine basin style study shows that there are two types and four modes of structural style. They are half graben with compensate fault and without compensate fault, and complex half graben with compensate fault and without compensate fault. An integrated sequence comes into being a suit of regional assemblage of source rock, reservoir and caprock. The main source rock is the dense tract between the TST to the HST, and it is also the better caprock. The favorable reservoir often developed in the bottom of the LST and TST, the top of the HST and in the RST. There are four types of the regional source reservoir caprock assemblage, such as top source bottom reservoir, top reservoir bottom source, sid source side reservoir and itself source itself reservoir. Lithological oil and gas pool developed in every sytem tract. Moreover, the structural oil pool is the main type of the HST and the unconformity oil pool can be found in the RST. |
