摘要:

利用油气化探方法分析南海北部采样点海水中的甲烷气体的浓度, 发现在甲烷浓度分布图中有7个异常高的位置, 其中的一些区域已经探明有油气藏的存在, 结果表明通过海水甲烷浓度来探测油气藏是可行的, 对今后的海洋油气探测具有重要的指导意义。

Oil and gas geochemical exploration in the northern South China Sea——A case study of methane concentration

WANG Qing-guang,XU Rui-song,WANG Jie,CHEN Yu

Abstract:

We measured the concentrations of methane in seawaters at diiferent sampling points in the northern South China Sea, and found that there were seven locations with unusually high concentrations of methane. Some of these locations had proved to be the sites of reservoirs, indicating information of seawater methane concentration may provide important guidance for future marine oil and gas exploration.

Key words: gas exploration methane hydrocarbon seepage
