The Study On Skeleton Section Contrast And Sedimentary Characteristics Of Fuyang Oil Layer InYushulin Oilfield

After 20 years of rolling development for Fuyang reservoir of Yushulin oilfield,has formed 12 development blocks,But the oilfield has not unified stratigraphic scheme, leading to reservoir clutter.In this paper, through the analysis of Yushulin Oil field drilling data, the distribution of oil layer and comparative reservoir deposition, closed the skeleton section Fuyang reservoir is established 13 horizontal and 11 vertical, construction of Fuyang unified stratigraphic framework. Yushulin Oil field is far away from the source of Fuyang reservoir slope in fluvial delta depositional system, by the analysis of single well comprehensive analysis and provenance characteristics determine reservoir sedimentary characteristics, and the sources of sediments in the northeast, the sedimentary environment of water power environment, has the characteristics of erosion bedding, particle size separation difference.Deposition of Fuyang phase system performance for the meandering river facies, delta plain subfacies and delta front subfacies, delta front subfacies evolution series, the energetic meandering river and delta plain facies for high quality reservoir development.
