油田注水管网拓扑结构自动设计方法研究

Research on Automatic Design Method of Topological Structure of Oilfield Water Injecting Pipeline Network

油田地面注水管网系统是一个大型的复杂的流体网络系统,该系统的设计工作量大,而且设计方案的合理性直接影响整个系统的初期投资和投产后的运行成本。文章给出了油田注水管网拓扑结构优化设计的数学模型,分析了其求解的复杂性。针对其计算量大和不易求得精确解的特点,从实际应用的角度出发,在分析现有管网结构特点的基础上,将管网拓扑结构优化设计划分为多个子任务,引进迭代的思想以求得该问题的近似解。通过设计实例检验了方法的可行性和正确性。

This paper presents the mathematic model of automatic optimum design for topological structure of oil field water injecting pipeline network and analyzes the complexity of solution.The optimum design of pipeline network topological structure is divided into several subtasks and an iterative method is introduced to obtain approximate solution.The design examples have verified the feasibility and correctness of the method.
