【摘要】 三步建模法强调建立等时地层对比格架是储层建模的关键,即首先借助地震、测井和钻井岩心等资料,利用高分辨率层序地层学理论建立精细的等时地层对比格架,继而在格架内以不同层次的旋回层序建立沉积微相模型,从而在沉积微相的约束下建立储层物性模型。三步建模法应用于赵凹油田的结果显示,所建立的模型较好地反映了储层地下特征,经验证效果较好。更多还原

【Abstract】 Most oilfields have entered mid-late phase of development,and reservoir modeling requires higher precision.Three-stage modeling emphasizes that the construction of detailed framework of reservoir is the key to reservoir modeling.The three stages include 1) the establishment of a detailed synchronous framework of the reservoir on the seismic,logging and coring data;2) the building of sedimentary microfacies modeling in the framework at various levels;and 3) the building of the model of reservoir petrophysical parameters under the control of sedimentary microfacies.The application of this modeling in Zhaowa Oilfield indicates that the model established in the three stages reflects the characteristics of the reservoir and yields satisfactory production.更多还原
