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。

Abstract

According to fluid inclusion and recovery of buried history , we discussed the timing of petroleum

fo rmation and stages of its accumulation in the third member of Shahejie Formation in the Binhai noseshaped

high structure .The pet roleum in the third member of Shahejie Formation was accumulated at late

period .The hyrocarbons in the Qs1 well were discontinuo usly filled for two stages (i .e .early period and late period).In accordance with tectonic activity , hydrocarbons- generating and exhausting history , oil and gas migrating and accumulating hi story , we consider that the hydro carbon accumulation in the third member of Shahejie For mation was mainly const rained by correlation between hydrocarbon generation stage and structural development .Thus , a phenomenon that oil was distributed in the shallow place and gas w as in the deep one occurs in the in the third member of Shahejie Formation as a prospecting areas for the large size pet roleum pools .
