指出:莺歌海盆地是新生代发育的一个高温盆地,其高地温场及高大地热流值主要集中于盆地中部坳陷区的泥底辟构造带;由于热流体活动的分区分块与分层的局部性侵入,导致了CO₂等非烃气及烃类气运聚富集亦县分区分块与分层性。认为泥底辟发育演化及热流体上侵活动是控制天然气尤其是CO₂等非烃气运聚乃至富集成藏的主导因素,而CO₂等非烃气与烃类气的运聚时间及运聚通道的差异,则是控制和制约烃类气与非烃气差异运聚及富集成藏的关键所在。

Yinggehai basin is a high geotemperature basin that developed at Eogene, and its high geotemperature field and high value of terrestrial heat flow mainly concentrate in the shale piercement belt of central downwarp area in basin. Development and evolution of shale piercement bell and especially upwelling action of hot flow body in late Pliocene epoch are close related with the migration and accumulation of natural gas and especially non-hydrocarbon （CO₂）. The local invasion of hot flow body, which is characterized by different layer, block and district, leads the migration and accumulation of hydrocarbon and non-hydrocarbon （CO₂） to possess the same characteristics. And the development and evolution of shale pierce merit and upwelling action of hot flow body is the dominant factor which influence the migration, accumulation and reservoir forming of hydrocarbon and especially non hydrocarbon （CO₂）. The difference between hydrocarbon and non-hydrocarbon （CO₂）on time and channel of migration and accumulation is the main factor which control and constraint the different migration, accumulation and reservoir forming of hydrocarbon and non-hydrocarbon.
