摘要: 黄河口凹陷是一个富生烃凹陷,目前已发现的油气藏及含油气构造大多具有埋深中浅层、原油密度中等、油质好、产能高等特点。纵向上发育多套含油层系,油气主要分布于新近系中。新近系油气成藏的主控因素为:近源、晚期快速成藏;浅水三角洲沉积体系为优质油气藏形成提供了空间;晚期走滑伴生断层是中央构造带油气富集的关键。

Abstract: Huanghekou sag is prolific hydrocarbon sag, in which discovered reservoirs and oil-gas bearing structures are most characterized by medium to shallow buried depth, medium density of crude, good oil quality and high productivity. Multiple sets of oil- bearing sequences are found in vertical direction, mainly distributed in Neogene system. The major control factors of petroleum accumulation in Neogene are as follows: 1) near the hydrocarbon source and rapid accumulation in late period; 2) shallow-water delta deposit system provides the reservoir spaces for forming premium reservoir, and 3) late strike-slip associated fault is the key of oil-gas enrichment in central structure zone in Huanghekou sag.

Key words: Huanghekou sag, petroleum distribution, enrichment, late hydrocarbon accumulation, shallow-water delta, strike-slip associated fault
