摘要

本文利用济阳坳陷3个地区5口深井(>4000ｍ)天然气的碳同位素、氩同位素、轻烃组成和地质背景等多种信息,采取天然气－源岩吸咐气直接对比法、天然气－生油气洼陷中原生油气藏原油伴生气间接对比法、氩同位素分析法、成藏条件分析法等,对不同地质条件下的气源进行了有效地追踪,最后建立了各自的成藏模式。

Abstract

Multiple information,such as carbon isotope,argon isotope,light hydrocarbon composition and other geological data,from 5 deep wells(4000m)of 3 areas in Jiyang depression was used to correlate natural gas with absorbed gas in source rocks directly and to correlate natural gas with associated gas in oil accumulation indirectly.The natural gas was traced effectively.The accumulation patterns of gas were proposed.
