| 摘 要： | 通过对文留气田天然气气源对比追踪，确定了该气田天然气充注点和充注方向；通过源岩主排烃期及流体包裹体研究，综合判断出文留气田充注成藏的时间和期次；采用流体包裹体GOI技术，恢复了气藏的古气水界面，通过研究古今气水界面的关系，综合分析了气藏演化历史和保存情况。在解剖文留气田的基础上，对东濮凹陷煤成气成藏机理进行综合分析，建立了东濮凹陷煤成气成藏模式，为东濮凹陷近期寻找煤成气藏提供了依据。

| Abstract: | This paper defined natural gas injection point and injection direction for Wenliu gas field combining with gas source correlation tracing. It studied the period of most hydrocarbon drainages for the source rock and its fluid enclosure so as to make it clear when and how many times the injection gas reservoir formed. By using GOI technique for fluid enclosure, paleo gas-water contact of gas reservoir has been restored, its revolution history and preservation have also been analyzed comprehensively with relation study of paleo-present gas water contact. Based on careful study of Wenliu gas field, this paper analyzed formation mechanism of coal bed gas reservoir, then built a reservoir formation model and provided an important basis for recent seeking coal bed gas reservoir in Dongpu depression. |
