摘要: 从酒西盆地新生代的构造应力场与滑脱面、运动学特征、沉积构造和构造模型等方面入手,论证了酒西盆地的性质,认为新生代酒西盆地为背驮于北祁连山逆冲推覆席体上的盆地,盆内的构造和沉积特征都取决于北祁连山推覆构造的活动强度。简要分析了新生代酒西背驮式盆地与油气成藏的关系。指出北祁连山山下掩埋了巨厚的白垩系烃源岩,强烈挤压的热环境为烃源岩的成熟提供了有利条件,逆掩推覆带是有利的油气勘探区。

Abstract: This paper probes into the characteristics of the Cenozoic Jiuxi basin from its present tectonic stress field, decollement surface, kinematic feature, sedimentary structure and structural model. It is suggested that the Cenozoic Jiuxi basin is piggyback basin on the north Qilian nappe, where the structural and sedimentary features are all controlled by the thrusting intensity of the north Qilian nappe. Also, this paper makes a brief analysis of the relationship between such a basin and hydrocarbon accumulation.

Key words: Jiuxi basin, piggyback characteristic, nappe, hydrocarbon accumulation
