油田供水系统调度优化方案研究

Study of Optimization Method of Water Distribution System in Oil Field

针对油田供水系统的现状,建立了油田供水管网的数学模型以描述供水系统的基本特征。在保证无含油污水外排的前提下,建立了以系统运行成本最小的目标函数,确定了目标函数的约束条件,提出了基于模式搜索理论的两层递迭代的优化方法。实际应用表明,数学模型正确,算法稳定。

According to the present of water flooding system in oil field, the paper sets up the mathematical model of water flooding pipe system to describe the basic characteristic of water flooding pipe system. Premising no sewage outer row, an objective function that system operat- ing cost is the lowest is set up and the restriction conditions of objective function are defined as an optimizing method of two-stage hierarchical iteration based on pattern search method theory is brought forward. The practical application shows that the mathematical model is correct and the algorithm is stable.
