| Abstract (English): | 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 simulation 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 reservoir 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 oilfield, 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. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 大庆油田传统的油藏模拟以区块为单位, 边界效应对模型的影响较大, 且无法进行全藏分析。为扩大模拟规模, 实现开发区级全藏模拟, 从而在宏观层面指导油田生产, 基于大庆油田黑油并行模拟软件 PBRS, 通过更新解法器算法、提升 数据通信并行效率、优化存储架构, 成功研发出亿级网格油藏模拟器。同时, 通过严格的海量数据质控, 构建了萨中开发 区特大油藏模型。该模型包含 1.06×108 个网格、23 801 口井及 161 个模拟层, 在历史拟合计算中, 最快仅用 24 h 便完成 62 a 开发历程的模拟, 首次实现百层万井模型的高效拟合, 突破了油藏 模拟技术在实际应用中的规模极限。油田整体模型相较 于小区块模型, 具备显著的完整性优势。萨中开发区全藏模型刻画出了老油田的开发现状: 断层附近富集大量剩余油, 小 区块边界处井网稀疏, 过渡带射孔不完善以及薄层动用程度偏低等。研究成果充分验证了全藏模拟技术可为特大油藏开发 策略的科学制定提供指导。 [ABSTRACT FROM AUTHOR] |
