济阳坳陷凸起带浅层气成藏主控因素及模式

Main Controlling Factors to Form Shallow Gas Reservoir and Reservoir-forming Models in Uplift Belt,Jiyang Depression

从济阳坳陷浅层气藏成藏因素入手,分析了控制天然气成藏分布的气源、沉积、构造、圈闭、储盖层等因素,总结了凸起带浅层气成藏的3种模式,认为成藏模式不同油气富集规律也有差异。

In this paper,some factors to form shallow gas reservoir in Jiyang Depression are studied at first;and then,the main controlling factors are analyzed,including gas source,sedimentary,tectonism,trap,reservoir and caprock;thirdly,three reservoirforming models for shallow gas in uplift belt are summarized;at last,the conclusion that different models may result in different hydrocarbon-accumulation rules is made.
