松辽盆地火山岩高含CO2气藏包裹体特征及成藏期次
Inclusions Characteristics and Pool-Forming Periods of High CO2 Volcanic Gas Reservoirs in Songliao Basin
摘要
Abstract
On the basis of detailed observation of petrography, and this study defined the types, periods and compositions of fluid inclusions in the volcanic rocks of the Yingcheng Formation in Songliao basin, using the characteristics of fluid inclusion, homogenization temperature, gas composition and carbon isotopes. In addition, the pool-forming periods of volcanic gas reservoirs with a high content of CO2 were analyzed. Integrated geological and geochemical evidence shows that hydrocarbon accumulation features in the volcanic CO2 -bearing reservoir in Songliao basin contain two accumulation periods characterized by-successive recharging process, I. E. , sedimentary period of Quantou-Qingshankou formations and the middle-late stage of Nenjiang Formation deposition. CO- was recharged in the Himalaya period, later than hydrocarbon gas.关键词
