东濮凹陷文南油田文79块沙二下亚段沉积微相研究
Sedimentary microfacies in the lower 2nd member of Shahejie Formation in the Wen 79 block of the Wennan Oilfield in Dongpu Depression
目前对文南油田文79断块沙二下亚段油藏的沉积微相研究还存在一些争议，重新认识研究区沉积微相,对后期开展精细油藏描述，指导剩余油的挖潜,具有重要的现实意义。对研究区岩石学特征、沉积构造特征、粒度特征、测井资料等进行综合分析和沉积微相建模，认为文79断块沙二下亚段发育一套干旱、半干旱环境下的分支河沉积体系，识别出河道充填沉积、近漫溢、远漫溢和河漫湖泊等沉积微相类型。
Sedimentary microfacies in the lower 2nd member of Shahejie Formation reservoir in the Wen 79 block have been investigated for many years, At present there are still some unsolved controversies. Microfacies analyses in studied area have an important practical significance in finely describing reservoir and exploiting the remaining oil. Based on comprehensive analyses of petrological characteristics, sedimentary structure, grain size characteristics, logging data and sedimentary microfacies modeling, we think the lower 2nd member of Shahejie Formation in the Wen 79 block was deposited in Distributive Fluvial Systems in arid and semiarid climate. River sedimentary filling, nearly overflowing , far overflowing and alluvial lake microfacies have been recognized.
