摘要
大庆喇嘛甸油田SⅡ油层组沉积体系以河流-三角洲为主,河流同期平面上具有多变性、垂向上多期河道相互切叠,等时对比存在困难。采用"重点井沉积时间单元划分—标准层﹑参照层借鉴对比—平面井网对比"这一方法,对研究区301口开发井进行了精细划分、对比,在此基础上,通过测井微相模式的建立和沉积微相的研究,精细刻画了各沉积时间单元砂体空间分布规律,为剩余油的预测提供了可靠的地质依据。
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.
