在系统调研氢气的分布及成因研究现状的基础上,对济阳坳陷部分油气井中天然气中的氢气含量进行了研究,并对其成因进行了初步划分。济阳坳陷天然气中氢气的含量普遍较低,在有R/Ra测试值的井中,氢气的H2/3He值普遍低于20×106,具有明显的幔源特征。因此,在这些井中,幔源氢气伴随深部流体活动混入了天然气中。

The paper systemically studied the distribution and genesis of hydrogen gas in natural gas all over the world on the basis of former study. The hydrogen gas content was studied for some oil and gas wells in the Jiyang Depression, and their genesis was discussed at the same time. The hydrogen gas content was very low in the Jiyang Depression. The H2/3He value was all lower than 20×106 in the wells which had R/Ra value. It was suggested that the hydrogen gas raised from mantle.
