| 摘 要： | 曙光油田二区（简称曙二区）在构造上位于辽河断陷西部凹陷西斜坡中段曙光油田的南部。结合区域构造特点,对曙二区沉积环境中的岩石类型和砂岩结构、岩石相、沉积构造及粒度分布特征等相标志进行了研究,以此探讨曙二区沉积相特点和砂体展布规律。结果表明,曙二区S32、S33油层属于重力流远岸湖底扇沉积体系,发育有中扇和外扇亚相,内扇亚相不发育。中扇亚相分为辫状沟道、沟道间和沟道末梢3种微相,而外扇亚相有深湖泥微相。

| Abstract: | The Shuguang-2 Block was in the middle part of west slope of Liaohe western fault depression. Combined with the regional tectonic characteristics,rock types,sandstone structure,lithofacies,sedimentary structure,distribution characteristics of grain size and other facies marks were analyzed in detail. The results showed that S32 and S33 oil layers in the Shuguang-2 Block belonged to gravity-flow infralittoral sublacustrine fan sedimentary system,which developed subfacies of middle fan and outer fan without i... |
