摘　　要：莺歌海盆地中部坳陷区的泥丘构造可分为能量保存型和能量释放型。在地震反射剖面上，前者顶部和上覆地层呈隆起状，后者顶部和上覆地层呈塌陷状。能量保存型泥丘顶部和其周围的岩性圈闭是形成油气藏最有利的地方。The mud domes can be devided into typeⅠ(energy conservation) and typy Ⅱ(energy releasing) in centeral depression in Yinggerhai basin. The seismic reflection section shows that thetop and covers for typeⅠare arch formed and collapse formed for typeⅡ. Lithologic traps on top of typeⅠand its surrounding are the favorable areas for forming a reservoir.

关 键 词：油气藏 莺歌海盆地 石油生成
