| 摘 要： | 通过对阳信洼陷火成岩发育和分布特征的分析、岩石矿物包裹体主挥发分和气藏组分含量的比较、火成岩的发育时代和岩石类型的不同所造成的含气性差异的分析，说明了火成岩与CO2气成藏的关系；研究表明阳信洼陷的CO2气主要为幔源无机成因气，幔源CO2气成藏受断裂活动和岩浆活动的控制，深大断裂的活动为岩浆活动创造了条件，岩浆是CO2气运移成藏的载体，火成岩的发育和分布为CO2气成藏提供了保障；结合阳信洼陷隐伏火山口的发育特征，采用幔源^3He通量法和CO2通量法对阳信洼陷CO2气的资源量进行了估算，为该区CO2气资源的勘探打下了基础。

| Abstract: | The CO_2 reservoir in Yangxin Sag is mainly of mantle inorganic genesis, controlled by fracturing and magma movement.It is found that the deep faulting could have created conditions for magma activities and that the magma could be the carrier for the migrating CO_2. It is also revealed that the development and distribution of igneous rocks make it possible for the CO_2 reservoir to form. While the relationship between the igneous rocks and the CO_2 reservoir is analyzed by the igneous rock growth, distribution characteristics, different rock types, the main volatile constituent and gas reservoir component concentration. The CO_2 reservoir value in Yangxin Sag is evaluated by mantle~3He method and CO_2 method, which estimates the potential reserve of CO_2 in the area. |
