以激光拉曼探针分析了胜利油田火山岩中的流体包裹体成分。结果表明,各包裹体流体中的主要成分是二氧化碳,此外,还有H2O、N2、H2、CH4、H2S等组分。含二氧化碳气藏区的新生代火山岩的流体包裹体中含有较多的CO2,一般在60%(摩尔百分比)以上;而不含二氧化碳气藏区的火山岩的流体包裹体中含CO2较少,多在60%以下。结合其他事实可以认为,该区二氧化碳气藏的形成与新生代富含CO2的碱性橄榄玄武岩浆有关。
The laser Raman probe is used to analyze the fluid inclusions in the volcanic rocks of Shengli Oilfield. The results show that the main component of fluid in each fluid inclusions is carbon dioxide, in addition, there are H2O, N2, H2, CH4, H2S and other components. The fluid inclusions of Cenozoic volcanic rocks with carbon dioxide gas reservoir area contain more CO2, generally more than 60% (mol%); while volcanic rocks without carbon dioxide gas reservoir area contain less CO2 and more Below 60%. Combined with other facts, it can be concluded that the formation of carbon dioxide gas reservoirs in the area is related to the generation of basaltic olivine basalts rich in CO2 enriched with CO2.
