| 摘 要： | 济阳地区煤系有机质二次生烃特征及勘探思路煤成气是一种重要的天然气资源，济阳地区上古生界煤系地层广泛分布，是煤成气形成规模聚集的基础。目前煤成气的勘探主要受到研究程度的限制。本文从煤成气成藏的关键因素之一，即“二次生烃”入手，通过模拟试验的方法揭示了二次生烃在成熟度、阶段产气率、生烃量、气态烃组分以及生烃模式等5个方面的基本特征，在以上机理分析的基础上研究了济阳地区的二次生烃期，最后提出了选择煤成气勘探有利区带的思路。

| Abstract: | Coal-genetic gas is a kind of important natural gas.Coal-bearing formations in upper Paleozoic were well developed in Jiyang area,and this is essential for scale accumulation of coal-genetic gas.Exploration practice of coal-genetic gas were confined mainly by low-level theoretic understanding at present.Aimed at one of the key factor for reservoir forming,viz.secondary hydrocarbon generation,and through simulation the paper bring forward characteristics of secondary hydrocarbon generation in 5 aspects,such as maturity,phase gas generation rate,gross hydrocarbon generation,constituent of gaseous hydrocaron and hydrocarbon generation model.Based on mechanism study.Different phases of secondary hydrocarbon generation in Jiyang area are analyzed in the paper,and concept to select exploration orientation is pointed out. |
