Abstract: The optimization of production and operation parameters of oil pipelines can effectively reduce operation energy consumption and improve the economic benefits of pipeline transportation. Aiming at the newly⁃built Qingha oil pipeline in the high and cold regions,the production energy optimization model was established with the constraints of the minimum energy consumption in production and operation,and the constraints of temperature constraints,pressure constraints,and oil pump operating characteristics constraints.In order to improve the solution efficiency,the hybrid PSO⁃Powell algorithm is used to solve the problem.The optimization results show that after optimization,the thermal energy loss is reduced by 38.3%,the pressure energy loss is increased by 90.3%,and the total energy loss is reduced by 26.3%.The energy saving effect is obvious.

摘要： 对输油管道进行生产运行参数优化，可有效降低运行能耗，提高管道输送的经济效益。针对高寒地区新建庆哈输油管道，以生产运行能耗最低为目标，以温度约束、压力约束、输油泵工作特性约束等为约束条件建立了生产运行参数优化模型。为提高求解效率，采用混合PSO⁃Powell算法对该模型进行求解。优化结果表明，优化后热能损失降低了38.3%，压能损失升高了90.3%，总能耗损失降低了26.3%，节能效果明显。
