【摘要】 本文运用地质、地震和测井等资料对陆西凹陷上侏罗统沉积体系特征进行了综合研究。该区上侏罗统发育了近岸水下扇、三角洲和以凹陷中古隆起为沉积背景的高垒斜坡扇等3种沉积体系,其中近岸水下扇为上侏罗统分布最普遍的沉积类型,构成本区主要储层,高垒斜坡扇是与水下古隆起有关的由滑塌作用形成的重力流沉积体,构成本区极富特色的沉积体系。更多还原

【Abstract】 This authors investigated the characteristics of the Upper Jurassic sedimentary systems in the Luxi hollow by using seismic and well logging data. In the Upper Jurassic of this area there occur three sedimentary systems ,i. e. ,offshore underwater fans , deltas and high-horst slope fans, of which offshore underwater fans are distributed most commonly and constitute major reserviore in this area and high-horst slope fans are gravity current sediment bodies formed by slumpimg and related to subaqueous paleo-uplift,which constitute special systems in this area.更多还原
