双河油田Ⅵ油层沉积微相特征

The Sedimentary Microfacies in Ⅵ Series Reservoir of Shuanghe Oilfild

为了弄清双河油田Ⅵ油层的储层发育特征,为该区剩余油的开发提供较为符合实际的储层地质模型,对该区沉积相类型进行了划分,该区主要发育扇三角洲前缘亚相,可细分为水下分流河道、河口砂坝、前缘席状砂、远砂坝、前扇三角洲泥、分流河道间湾共六种沉积微相。研究区可作为储层的砂体主要为水下分流河道砂体、河口坝砂体、前缘席状砂砂体及远砂坝砂体。

The division of sedimentary microfaeies in Ⅵ series reservoir of Shuanghe oilfield can learn the development features and can establish the fit reservoir geological model for the development of remaining oil. This area mainly develops fan delta front subfacies, which can be subdivided into six mierofaeies, which are subaqueous distributary channel, mouth bar, frontal sand sheet, distal bar, prodelta mud and interdistributary area. The main reservoir sand bodies are subaqueous distributary channel, mouth bar, frontal sand sheet, and distal bar.
