Study on In-Layer Heterogeneity of the Channel Single Sandstone Body in Each Facies Area of the Meandering River-Delta
Journal Title: Scholars Bulletin - Year 2016, Vol 2, Issue 3
Abstract
Abstract: There are three facies areas, that are meandering river, delta distributary plain and delta front in the reservoir layer of the BY region of the Daqing oilfield. SⅡ81、SII21、SⅢ8 are typical sedimentary time units which are respectively belong to each facies area. We Used statistic analysis method to obtain the subtle variety of the three permeability parameters- Kv, Tk and Jk- to make the research of the in-layer microfacies controlling heterogeneity of typical channel single sandstone body. Research indication: The in-layer heterogeneity of typical channel single sandstone body, the meandering river facies area’s is relatively most serious, the distributary plain’s is medium, and the delta front’s is relatively weak. Keywords: meandering-delta; typical sedimentary unit; interlayer; permeability; heterogeneity.
