摘要：

辽河盆地东部凸起古生界埋藏类型划分为相对沉降型、后期沉降型和长期抬升型3类。相对沉降型埋藏区,古生界可部分二次生油气,下白垩统梨树沟组具有生油潜力;后期沉降型和长期抬升型埋藏区,由于地层埋藏浅,很少有油气生成。从构造演化角度看,在古生界隆起,中生界凹陷的交汇区,可寻找古生界原生和次生油气藏,在单斜区,如有好的生油凹陷侧向配置,将可寻找到新生古储的古生界次生油气藏,以三界泡潜山成藏条件为好。

Abstract:

The Paleozoic burial types of the east uplift in Liaohe Basin could be divided into three kinds,i.e.relative subsidence type,later subsidence type and secular uplift type.Combined with the data of its geothermal evolution,the hydrocarbon property of this area was analysed.In the relative subsidence area,part of the Paleozoic group may re generate hydrocarbon and the Lishugou Formation of Lower Cretaceous may have hydrocarbon generating patential.The other two types have hardly any hydrocarbon due to their shallow burial depth.From the view point of structural evoluion,primary and secondary pools may be found in the conjunction parts of the Paleozozic uplifts and the Mesozoic depressions.If there are good source sags to match laterally monocline pools,secondary Cenozoic pools with Paleozoic source rocks may be found.
