摘要
歧东构造带具有浅层与深层构造相异的特征，主要产层是断层分割的河流相砂体。浅层油藏的形成受深层物源的控制，陡产状深切的断层是油气运移的主要通道，油气主要分布在与断层相接触的砂岩圈闭中。圈闭条件常常受断层和岩性双重控制；由于储层物性很好，良好的盖层和遮挡条件是该区油气成藏的关键因素。
Qidong field is
characterized by different structures from deeper to shallower strata, its main pay bed is fluvial
sandstone segmented by deep cutting faults The formation of shallower pools is restricted by the
deeper source with immigration channel of a fault to the targets that occur mainly in the traps
related to the fault The traps are frequently controlled both by fault and lithology Because of
reservoir with good petrophysics, a better seal and shelter is strongly required for pool formation
