摘要

砂岩侵入体是由沉积后的砂岩再活动并侵入到周围地层中形成的一种特殊砂体。从20 世纪80年代开始，人们对砂岩侵入体的重视程度日益增加，目前业已发现砂岩侵入体岩性油气藏。文中介绍了国际上有关砂岩侵入体的研究现状，概括了砂岩侵入体的结构模式、露头特征以及岩心、测井与地震识别标志，总结了砂岩侵入体的触发机制和流动机理，并对砂岩侵入体的石油地质意义进行了讨论。砂岩侵入体对油气藏的形成和油气勘探开发都具有重要的影响，是岩性油气藏勘探开发中应当注意的一个新领域。

Abstract

Sand injectite is a special kind of sand bodies which are formed by the remobilization of the original depositional sand. More attentions have been paid on sand injectites after 1980s by the discovering of series hydrocarbon reservoirs. The research status of sand injectites is introduced. The 3Darchitectural model, the outcrop characters and the recognization cretials of sandstone injectite in cores, well logging and seismic responses are summarized. The trigger mechanism and flowregime of sand injectites are concluded, and its geological significance is discussed. Sand injectites have important impaction for petroleum exploration and development, and it may be a new kind of lithological stratigraphic traps in exploration and development in China.
