六十年代初,黄骅坳陷在石油普查过程中,首先在北大港潜山构造带发现CO2气。七十年代初,又分别在翟庄子鼻状构造及友爱村断块再次发现高含量CO2气,以后又相继在不同的断块探井中也见到了CO2气流。勘探实践表明,港西地区井涌、井喷现象与富含CO2气密切有关,一些岩性尖灭油气藏也与CO2气含量有密切关系。

Depending on the summary of the geological characteristics of CO2 gas produced from Huanghua Depression, the paper states that the CO2 gas is a type of multiple sources.It can be either intergrowthed and accompanied with hydrocarbon gas and liquid hydrocarbon or hetero-growthed and accom-panied with oil/gas water in the pattern of water-soluble CO2 gas of multiple sources,meanwhile,it can be accumulated to be highly concentration CO2 gas and distributed on the high locations of petroliferous structures.The variations of CO2 gas content and the geological characters of CO2 gas producing can be used as a director for reconnaissance and exploration of the hydrocarbon gas and liquid hydrocarbon.
