摘要
将储运系统的南一油库、南三油库和北油库作为一个整体考虑,以系统总能耗费用最低为目标,建立了多站库优化数学模型,根据模型的结构特点,采用两级递阶优化方法将原优化模型分解成最优管道出站压力模型和出站温度优化模型两个子模型,两者之间通过迭代进行求解。应用该模型对大庆油田多油库生产调度工艺进行了优化,制定了不同油库的优化工艺参数,包括优化的外输温度、压力等。结果表明,优化方案与原方案相比可节约能源10.38%,具有显著的节能效果。
To consider Nan 1 oil depot,Nan 3 oil depot and Bei oil depot of storage and transportation system as a whole,and take the lowest total energy-consumption cost as the goal,a mathematical model for multi station optimization has been established.According to the structural characteristics of the model,the original optimization model can be divided into two sub models by using two level hierarchical optimization methods.They are the optimal pipeline output pressure model and the output temperature model.The two models can be solved by iteration.The production and dispatch scheduling process for multi storage depot can be optimized by using the model in Daqing oilfield,and some process parameters for different oil depot have been made,including optimization of output temperature,pressure and so on.The results show that 10.38%of energy consumption can be reduced by using the optimization scheme under comparing with the original scheme and the energy-saving effect is obvious.
