摘要 随着油气勘探的不断深入 ,我国东部地区主要含油气盆地勘探的主要目标逐渐转为一些较复杂的隐蔽油气藏 ,尤其是盆内的次级洼陷 ,已成为勘探的重要地区。多年的勘探实践表明 ,对于我国东部的陆相箕状盆地 ,洼陷中含油气是必然规律。在洼陷内最重要的油藏类型是砂体岩性与构造 岩性油藏 ,并且绝大多数为浊流成因。本文以山东济阳坳陷与昌潍坳陷的德南、牛庄、利津、博兴等几个洼陷为例 ,介绍洼陷生油条件的地震研究方法与三角洲 浊积扇体系中浊积岩发育区的沉积特征、油气富集规律及地震综合研究方法。 Some concealed oil and gas pools especially secondary depressions in eastern China are now becoming the important targets of oil and gas exploration. The types of oil pools consist dominantly of lithologic and structural lithologic oil pools of turbidity current origin. The combination of oil generating conditions, sedimentary characteristics and oil and gas accumulation by using seismic techniques as indicated in the Denan, Niuzhuang, Lijin and Boxing secondary depressions has led us to conclude that the presence of turbidites is the main cause for the occurrence of oil and gas in continental secondary depressions. Due to the presence of undercompaction, seismic techniques may be employed as a useful tool for interpreting the oil generating conditions of the moderate to thick bedded dark mudstones.
