摘要(Abstract)：

基于英台断陷深部火山岩气藏的烃源岩及储层特征,分析火山岩气藏源/储品质、耦合关系、输导体系和气藏特征等,研究成藏主控因素和成藏规律,预测研究区天然气勘探有利区.结果表明,英台断陷火山岩气藏存在下生上储和侧生侧储两种类型,其中下生上储型主要发育于大屯地区,主要以断裂为输导通道沟通沙河子组源岩,沟通源储的断裂控制气藏的分布;侧生侧储型主要发育于五棵树地区,成藏的关键在于火山岩储层能否在侧向上与营城组二段有效烃源岩直接相连,对接面处易于气藏的形成,且气藏规模大、丰度高,随着天然气运移距离的增加,气藏规模和丰度逐渐降低.该成果有助于认识英台断陷火山岩气藏及剩余资源的分布,确定勘探有利区.
