摘要
滨海断鼻位于黄骅坳陷中北区,为依附于滨海断层下降盘的断鼻圈闭,钻探证实该断鼻具有含油气层系多、油气藏类型多、平面叠置连片及油气复式聚集的特点。烃源岩分布、构造演化分段性、砂体分布及烃源岩母质类型等因素决定了古近系油气的富集程度及展布规律。认为明确研究区油气的主控因素对确定不同构造部位的油气勘探方向有重要意义。
The coastal fault nose zone in the north central of Huanghua depression is a fault-nose pattern trap, which is controlled by the downthrown side of the coastal fault. The drilled results have proved that this fault nose zone is characterized as hydrocarbon multi-layers, variegated reservoir types, vertical superimposition and plane in- terconnection, and multiple accumulation of hydrocarbons. The accumulation and spatial distribution of hydrocarbons in Eogene is constrained by source rock distribution, structural evolution, distribution of sandstone body, and type of source rocks. The controlling factors of hydrocarbon accumulation in study area will give guidance for selec- ting the exploration direction in different structural locations.
