在前人的研究基础上，详细地总结了CO2分布与热流体活动在平面、纵向和时间上的对应特征，认为热流体活动与CO2分布的确存在一定的对应关系；同时，认为热流体可以促进CO2气源形成，可作为CO2气运移的载体，同时促进运移通道的扩大，也为CO2气运移提供能量，流体在上侵过程中与围岩发生反应，改造了CO2气储层，热流体在向上释放能量的过程中，造成上覆地层的拱起，形成圈闭，最终也可控制CO2气成藏。

The research shows that in the Yinggehai basin, the formation of CO_(2) reservoir which is crust-sourced and crust-mental-mixed-sourced, mainly controlled by local action of hot fluid in the mud diapir area which is multi terms and multi zones and by physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO_(2) in the Qiongdongnan basin and Pearl River Mouth basin is mainly controlled by volcanos activities and by the exist of large faults which reached to base to connect the gas from the mantle. According to different mechanism ang formation of reservoir os the the crustal rock-chemical genesis and volcano-and mantle-sourced CO_(2), we can follow the source of it, analysis and predict the migration and accumulation and distribution model of gas and espacially CO_(2), so as to help to make the plan of petroleum exploration and reduce the risk of exploration.

The study shows that in various continental downfaulted basins in eastern China,the China East Sea basin of the southeast sea region and the continental shelf—Qiongdongnan basin and Zhujiangkou basin—of the northern South China Sea,CO2 in CO2 reservoirs and CO2-rich oil/gas reservoirs is of typical volcanic mantle-derived type and that its migration and concentration is mainly controlled by mantle-derived volcanism and gas-conducting distribution of deep basement faults connected with the gas source at depth. CO2 is mainly sourced from substantial amount of CO2 associated with mantle-derived volcanism at the deep level of the crust. CO2 in the CO2 reservoirs and CO2-rich oil/gas reservoirs in the Yinggehai basin on the continental shelf of the northern South China Sea is of crust origin and crust-mantle mixing origin and mainly controlled by local,layer-by-layer and zone-by-zone,multiple intrusion of late hydrothermal fluids in mud diapir areas and physico-chemical processes of very thick Pliocene-Miocene marine calcareous sandstone and mudstone.
