| 摘 要： | 油气田上方地表微量元素的分布与油气田的分布有一定的关系,即在气田上方形成环状和顶端异常。通过微量元素与渗漏烃分析,发现新场气田的Cd不仅与烃类相关,而且与Mn聚为一类。利用中子活化分析和原子力显微镜观察不仅发现了天然气中含有微量元素,而且还证明其以钠米微粒的形式被上升气流运载迁移到地表,在气田地表形成微量元素分布异常。 |
| 关 键 词： | 微量元素 油气化探 新场气田 上升气流 |

| Abstract: | There is a certain correlation between distribution of trace elements on the surface of the earth and distribution of oil and gas,for trace elements form the circularity and top abnormal distribution on the surface of gas field.By analyzing trace elements and microseepage of hydrocarbon,we find that Cd in Xinchang gas field does not only have the correlation with microseepage of hydrocarbon,but also can be classified to the same sort with Mn.Though analysis of INAA and AFM observation,we can not only find that natural gas contains trace elements,but also can prove that this trace elements be carried up in the form of Nano-scale particles by ascending gas flow and form trace elements abnormal distribution on the surface of the gas field. |
| Keywords: | trace elements oil and gas geochemistry XinChang oil and gas field ascending gas flow |
