The Features of Sedimentary Microfacies and Reservoir Physical Properties of Channel Gravity Flow Sandbody in Lianhua Interval in Gaosheng Oilfield

  • 摘要: 辽河断陷盆地西部凹陷北端的高升油田莲花油层受断陷湖盆基底结构的影响,沉积物从高差较大的湖岸倾泄到凹陷后,沿狭长的断槽向前延伸,属比较典型的水道式重力流砂体沉积。综合各种沉积环境标志细分出了主沟道、主沟道间漫溢微相、分流沟道、分流沟道间、分流沟道漫溢微相,前缘微相等六种微相。储集物性以分流沟道微相最好,主沟道微相次之,其它微相比较差。

     

    Abstract: The Lianhua interval in Gaosheng oilfield,located at the northern end of the western sag in Lioahe rifted basin,is typical channel gravity flow sandbody deposition.Under the influence of the basement structure of the rifted basin,deposits dumped into the sag from the lake bank with large elevation difference and went forward along the elongated trough faults.Six microfacies are recognized according to various sedimentary marks including main culvert,overflow between main culverts,distributary culvert,overflow be-tween distributary culverts and the front.The distributary culvert microfacies have the best reservoir physical proper-ties,the next is main culvert microfacies,and the rest are poor microfacies.
