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.
