摘要: 鄂尔多斯盆地中生界自下而上依次为岩性油藏、构造-岩性复合油藏、构造油藏。对该区不同类型油藏的成藏条件及盆地勘探现状的综合分析表明,油藏序列的形成受生油、油气运移、储盖组合特征等多种因素的控制,其中油源条件是形成本区油藏序列的主要控制因素,圈闭与油源岩的纵向距离是决定油源条件优劣的重要指标,盖层品质起着重要的制约作用。

关键词: 鄂尔多斯盆地, 油藏类型, 主控因素, 油源条件, 盖层

Abstract: The Mesozoic Ordos Basin developed the special oil pool sequence,which contains lithologic oil pool,lithologic-structural combination oil pool and structural oil pool from down to up.The comprehensive analyses on the different type of reservoir-forming condition and exploration status showed that the formation of oil pool sequence was controlled by many factors including source rock,oil-gas migration,and reservoir-cap rock combination.The source rock is the main controlling factor for generation of oil pool sequence.The vertical distance between trap and source rock is the vital index,which determines oil source condition.The quality of cap rock has significance for oil pool sequence.

Key words: Ordos Basin, oil pool type, key controlling factors, oil source condition, cap rock
