摘要

摘要: 在总结不同成因条件下CO₂成藏地球化学特征、形成条件、气藏分布以及受控的地质—构造环境的基础上,对松辽盆地不同类型火山岩CO₂气体脱气进行实验研究,得出了不同岩性的CO₂脱气参数;对韧性和脆性剪切作用的动力变质系统条件下构造变形岩石CO₂气体释放量进行了模拟计算;对接触变质作用条件下碳酸盐岩石CO₂气体释放量进行了地球化学模拟计算。在上述研究的基础上,提出了在火山脱气、动力变质和接触变质作用条件下CO₂的形成机制以及气体释放量的计算模型。指出了我国无机成因CO₂气藏的分布规律和勘探目标。

Abstract: This paper presents the general situation on the geological and geochemical characteristics of CO₂ pools,their forming condition and distributions as well as their controlled geological-tectonic environments.The degassing experiment of volcanic rocks in Songliao Basin presents the CO₂ releasing parameters for different types of volcanic rocks.Geochemical modeling calculation of CO₂ releasing has been done based on dynamic metamorphism caused by ductile-brittle shearing deformation.The amount of CO₂ releasing is calculated and its relative calculation model is proposed during the contact metamorphism in carbonate rocks.Based on research,the model for the calculation of CO₂ degassing and formation of CO₂ pools under the condition of degassing from volcanic rocks,dynamic and contact metamorphism have been established.The distributions of CO₂ pools and their exploration localities in China have also been proposed.
