摘要
油藏自动历史拟合的目标是通过优化算法自动匹配各井的开发指标,使数值化的油藏模型(如饱和度和压力分布)符合各个开发时期实际的油藏状态,从而保证油藏数值模拟再现油田开发全过程的正确性,并在此基础上预测将来的开发方案。相对于常规人工拟合,油藏自动历史拟合避免了研究人员生产拟合时的随意性和盲目性,大大减少了工作量。系统地介绍了目前中外自动历史拟合方法的研究现状和进展,总结归纳了确定性、随机性和混合3类优化方法,详细说明了常用算法各自的特点及应用范围,探讨了目前研究存在的不足,最后提出了拟合方法下一步的工作重点和研究方向。
The goal of automatic history matching is to match the development index of wells automatically by means of algorithms optimization and make the numerical reservoir models (such as saturation and pressure distribution) in accordance with all of the reservoir status during development history.So reservoir simulation can predict future development plan on bases of reflecting the whole process of oil field development correctly.Compared to conventional manual history matching,automatic history matching can not only avoid randomness and blindness caused by researcher,but reduce the workload significantly.The paper introduced systematically the present research status and advances of automatic history matching methods in reservoir simulation home and abroad,and summarized the deterministic,stochastic and hybrid methods.Characteristics and application ranges of various methods frequently used were evaluated in detail and the current drawbacks and defects were also discussed.Finally,future studies of automatic history matching were proposed.
