    Dynamics of Gas Accumulation in Yinggehai Basin

    • 摘要: 采用地质与地球化学、宏观与微观相结合的研究方法, 探讨莺歌海盆地的成藏动力学过程, 具体表现在: 通过成藏流体非均质性剖析揭示了底辟浅层气田多源混合-幕式充注的成藏特点, 流体活动的地球物理特征和地球化学资料显示底辟断裂为深成天然气向上运移提供了良好的通道, 而异常高压是流体压裂运移的关键动力, 并驱使梅山-三亚组烃源岩生成的天然气向上运移、聚集和散失.由于中央坳陷带气源丰富, 存在供大于散的物质基础, 尤其是“幕式”集中运移具有高的排烃效率, 因此, 莺歌海盆地底辟带浅层构造在距今1.2~ 0.1Ma如此短暂的时间里天然气依然能够聚集成藏.
