苏北黄桥地区上第三系富氦天然气成因探讨

DISCUSSION ON ORIGIN OF UPPER NEOGENE HELIUM-RICH GASES IN HUANGOIAO, NORTH JIANGSU

本文对苏北黄桥地区浅层含氦气藏的天然气主要组分进行了成因研究,指出浅层天然气来自深部和浅部不同气源,本区有良好的勘探前景。

The study on origin of Helium-rich natural gases in Upper Neogene shallow layerpools in Huangqiao Region, North Jiangsu shows that the hydrocarbon and CO_2 came fromdeep areta, N_2 was originated from the thermodegradation of organic matter and radio-active materials in the deep and shallow beds, and He was mainly of radio-active orgin.
