Eleven CO₂ gas fields(pools) have been discovered in the Huanghua and Jiyang depressions of Bohai Bay Basin, East China. The analyses of natural gas geochemical data in the CO₂ gas fields(pools) reveal: First, there is a positive correlation between CO₂ content,δ¹³CCO₂ values and R/Ra values, but a negative correlation between CO₂ content and CH₄ content; Second, the elevated δ¹³CCO₂,R/Ra and ⁴⁰Ar/³⁶Ar values show that CO₂ is mantle-derived; Third, organic and inorganic alkane gases are both discovered in the CO₂ gas fields of the Huanghua Depression, and the alkane gas in the Jiyang Depression is mainly oil-type.
