Title: Study on Sedimentary Microfacies of Monosandstone Body of Fluvial Facies Stratum——By Taking SII Oil Formation of Lamadian Oilfield for Example
Abstract: SⅡ Oil Formation of Daqing Lamadian Oilfield mainly developed river-delta depositional system,fluvial deposits had feathers of multi-changes in the plane and multiphase river channel cutting overriding in vertical direction,it was difficult for isochronic contrast.The method of classification of sedimentary time unit in key wells-standard layer and reference layer comparison-planar well pattern contrast was used for fine division and comparison of 301development wells in the studied area.On the basis stated above,the spatial distributions of sandstone body are figured out by the establishment of logging sedimentary microfacies mode and the studying of sedimentary microfacies.It provides reliable geologic foundation for the forecast of remaining oil.
