摘要
通过对渤海海域高含CO2油气藏地质与地球化学特征的系统分析,深入研究了CO2成因及分布主控因素。渤海海域环渤中地区油气藏中CO2主要为幔源无机成因,辽东湾地区油气藏中CO2含量小于1%,为有机成因。新构造运动期强烈活动深大断裂空间展布和新生代岩浆活动控制了幔源无机CO2的分布,沿活动深大断裂走向方向活动较弱部位有利于幔源无机CO2聚集成藏。
The origin of CO2 and the main controls over its distribution were deeply researched in Bo- hal Sea, by analyzing systematically geology and geochemistry of the high-CO2 hydrocarbon reser- voirs. In the circum-Bozhong area, CO2 in hydro carbon reservoirs originated dominantly from man- tle degassing, and in Liaodong bay, CO2 less than 1% in reservoirs tends to be organic in origin. Tile faults are favorable for accumulation mantle-derived CO2
