Sandy Braided River Sandbody Configuration and Remaining Oil Distribution Pattern

doi:10.3969/j.issn.1006-6535.2020.04.002

Abstract

Abstract: In order to identify the effects of different-order sandbody configuration patterns, internal interlayer and rhythm within braided-river on the remaining oil distribution in the middle-late development stage, The braided river and lithofacies of the middle Jurassic Yungang Formation in the Tieluqiao profile of Shanxi Datong were detailed characterized and analyzed based on the field outcrop lithology and sedimentary structure. Result indicates that there are nine lithofacies categories can be identified and three genetic sandbody categories, including channel sandbody, channel bar sandbody and point-bar sandbody. The point-bar sandbody is classified into the major genesis sandbody in the braided river channel from fine dissection of longitudinal sandbodies and detailed modern river sedimentation. In addition, 9 remaining oil enrichment patterns were established by combining with the fourth-order and fifth-order configuration interfaces and the deployment of injection-production well pattern. This research could provide a reliable reference for further remaining oil recovery and enhancing oil recovery for the sandy braided-river reservoirs in the Yungang Formation.

Key words: braided river, sandbody configuration, point beach, remaining oil, Tieluqiao profile, Shanxi Datong
