立足于现代数值模拟技术的前沿领域 ,开展了适合百万节点模型的油藏数值模拟技术研究。运用国际上最新推出的并行计算机和并行模拟软件 ,探索出做百万节点模拟的 4项实用技术 ,即数值模型的自动化建模技术、精细建模与模拟计算中时间步精确控制技术、模拟参数场的交互更新技术以及工艺措施拟合的数字化技术 ,并据此技术实现了大庆油田实际油藏区块 12 4× 10 4 个节点的数值模拟 ,给出了层状砂岩油藏高含水阶段薄油层中的剩余油分布及调整挖潜的开发指标预测结果。通过百万节点油藏数值模拟技术的研究和应用 ,实现了对薄、差油层剩余油的精确描述 ,为大庆油田的调整挖潜提供了更多有价值的数值依据 ,总体上将油藏数值模拟技术提高到了一个新的水平。
According to modern reservoir simulation technology,a study of reservoir simulation technology that is suitable for million-gridblock model is carried out. In this study, the latest parallel computer and parallel numerical simulation software are employed.Then four practical techniques for million-gridblock models are developed: automatic technique of numerical modeling, accurate control technique for time step between fine modeling and simulation computing, mutual and renewal techniques for simulation parameter field and digitalization technique for technic steps. Based on these techniques developed for reservoir simulation, a simulation work that has 1.24 million gridblocks for Daqing Oilfield is completed.The result of this simulation work includes the distribution of remaining oil and the prediction of adjustment and development index at high water cut stage for thin sheet sand reservoir. This study makes a significant improvement in reservoir simulation technology.
