摘要

本文讨论了济阳拗陷孤岛等地浅层天然气的地球化学特征,这些天然气曾遭受过严重的细菌降解。由于细菌降解作用改变了该天然气原有的地球化学面貌,使气源对比发生困难。本文利用天然气重烃富集技术,在天然气中检测出了甾萜生物标志物,并借助稀有气体同位素资料,确定了该类气体的气源,为明确勘探目标提供了依据。

Abstract

This paper gives a discussion on geochemical characteristics of natural gas in the shallow reservoir in Gudao area of Jiyang Depression. The gas suffered serious biodegradation. Original geochemical features are changed because of biodegradation. Correlation of gas-sourece for this gas is difficult. This paper uses technology of heavy hydrocarbon concentration of natural gas to detect biological markers of sterane and terpane, and defines gas-source of biodegradation gas with the aid of data of rare gas isotopes Basis is provided for Clarifying exploratory target.
