论文摘要
最佳的井位置和井注射生产对于储层开发至关重要,以最大程度地利用项目寿命。荟萃分析算法在解决复杂,非线性和非连续优化问题方面表现出良好的性能。但是,在优化过程中涉及大量数值模拟运行。在这项工作中,提出了一种新型,有效的数据驱动的进化算法,称为通用数据驱动的差异进化算法(GDDE),以减少在良好的安装和控制优化问题上运行的模拟数量。概率神经网络(PNN)被用作选择信息性和有前途的候选者的分类器,并且基于欧几里得距离的最不确定的候选者被预先筛选并使用数值模拟器进行评估。随后,局部替代模型是通过径向基函数(RBF)构建的,由优化器发现的替代物的最佳构建,由数值模拟器评估以加速收敛。值得注意的是,通过解决高参数次级优化问题,可以优化RBF模型和PNN的形状因子。结果表明,这项研究中提出的优化算法对于二维储层和鸡蛋模型的关节优化的良好置换优化问题非常有前途。
Optimal well placement and well injection-production are crucial for the reservoir development to maximize the financial profits during the project lifetime. Meta-heuristic algorithms have showed good performance in solving complex, nonlinear and non-continuous optimization problems. However, a large number of numerical simulation runs are involved during the optimization process. In this work, a novel and efficient data-driven evolutionary algorithm, called generalized data-driven differential evolutionary algorithm (GDDE), is proposed to reduce the number of simulation runs on well-placement and control optimization problems. Probabilistic neural network (PNN) is adopted as the classifier to select informative and promising candidates, and the most uncertain candidate based on Euclidean distance is prescreened and evaluated with a numerical simulator. Subsequently, local surrogate model is built by radial basis function (RBF) and the optimum of the surrogate, found by optimizer, is evaluated by the numerical simulator to accelerate the convergence. It is worth noting that the shape factors of RBF model and PNN are optimized via solving hyper-parameter sub-expensive optimization problem. The results show the optimization algorithm proposed in this study is very promising for a well-placement optimization problem of two-dimensional reservoir and joint optimization of Egg model.
