摘　　要：对集油管线输运、单井储油罐拉油两种生产模式进行建模并实现动态模拟,进一步探究了两种模式的加热负荷变化规律及最优加热参数的确定。分别设计了单井集油管线输运及储油罐拉油两种生产模式的分布式能源系统方案,包含水套加热炉、电伴热、太阳能集热装置、太阳能蓄热装置、空气源热泵。对5种热源进行热力计算,在此基础上建立两种分布式能源系统目标函数及约束条件,对两种分布式能源系统进行优化,给出不同模式、不同季节、不同时刻所需电伴热占比,可达到对热源的合理利用,使得投资费用与运行费用最小,同时对几种分布式热源进行了经济性分析。In this study,two production modes of oil-collecting pipeline transportation and oil-pulling single-well oil storage tanks are modeled and dynamic simulations are performed.Moreover,the heating load-variation rules and optimal heating parameters of the two modes are further explored.The distributed energy system schemes of crude oil transportation in single-well oil-collecting pipelines and oil-pulling oil storage tanks are designed,which involve a water jacket heating furnace,electric heat tracing,a solar heat-collecting device,a solar heat storage device,and an air source heat pump.Thermodynamic calculations of five types of heat sources are performed,and the objective function and constraint conditions for the two types of distributed energy systems are established to optimize the systems.Results show the required electric heat-tracing proportion of different modes,seasons,and times to achieve the rational use of the heat source and minimize investment and operational costs.Furthermore,economic analysis of several distributed heat sources is performed.
