亿级网格数值模拟技术及其在大庆油田萨中开发区特大油藏中的示范应用
Hundred-million-grid numerical simulation technology and its demonstrative application in giant reservoirs in Sazhong development zone of Daqing Oilfield
摘要
Abstract
Traditional reservoir simulation in Daqing Oilfield is based on blocks,and the boundary effect has great influence on the model,making whole reservoir analysis impossible.In order to expand the scale of reservoir simula-tion and achieve whole reservoir simulation in development zone level,and guide oilfield production at macro level,based on parallel black oil reservoir simulation software PBRS of Daqing Oilfield,hundred-million-grid reservoir simulator is developed successfully through updating solver to improve data communication parallel efficiency and optimizing storage architecture.Meanwhile,through mass data quality control,large-scale water flooding reservoir model is established.The model contains 1.06×108 grids,23 801 wells and 161 simulated layers.History matching calculation of 62 years development history is completed fastestly within 24 hours,achieving efficient matching of models of hundreds of layers and tens of thousands of wells for the first time,which breaks through the limit of reser-voir simulation technique in application.Compared with small block model,integral oilfield model has advantage of integrity.Whole reservoir model of Sazhong development zone characterizes the development situation of mature oil-field,with issues such as large amount of remaining oil near faults,sparse well patterns at boundaries of small blocks,imperfect perforation in transition zones and low producing degree of thin layers.The research proves that whole reservoir simulation technique can provide guidance for development strategy making of super-large reservoirs.关键词
