油气混输管网参数优化研究

Study on parameter optimization of combined network of pipeline

采用遗传算法对油田地面多相混输管网结构参数进行优化计算,建立了优化计算的目标函数、水力热力学模型及管网分析模型,用并列选择法和权重系数变化法进行求解。对双河油田地面集输管网的结构参数进行了优化计算,可以节省费用15％以上。

Adopting genetic algorithm, this paper optimizes the structure parameters of combined network of pipeline, as well as establishes object function which can optimize the computing method, hydraulic and thermodynamic models and pipe network analysis models. By applying the parallel selective method and weight coefficient method, the object function can be worked out and the cost saving is up to at least 15%.
