| 摘 要： | 侵入砂体是指深水沉积砂体在超压流体作用下侵入至上覆泥质沉积物中形成的砂体,它是深水盆地松散沉积物变形构造中常见的地质现象。侵入砂体由于其特殊的形成特点,可以明显改变原生沉积地层的几何形态和深水沉积物的物性参数,进而使储层复杂化,影响深水油气的勘探与开发,主要表现在:①侵入砂体改变了深水储层的性质及分布;②侵入砂体可能形成油气运移或散失的通道,并且改变了深水油气储层的垂向连通性;③大规模的侵入砂体本身也可以作为良好的油气储层;④侵入砂体的研究可以揭示未固结砂的流动机理,对于研究深水环境中广泛出现的浅水流的成因具有重要的借鉴意义。

| Abstract: | Sandstone intrusion is a common deform structure resulting from remobilization of unconsolidated sandstone in deep-water basin.Soft sandstone intrudes up into overlying muddy sediment due to pore overpressure,and becomes consolidated after pressure balance.Sandstone intrusion can significantly change primary depositional geometries and physical properties of deepwater sediments,and causes great variations in reservoir characters,which may significantly affect petroleum exploration and development in such re... |
