Abstract: 'Three box' exergy analysis optimisation method is applied to oil field system in order to identify and improve the weak links of crude oil gathering and transportation system. The universal 'black box', 'white box', 'grey box' models and balance equations of oil field analysis are established according to different requirements of rough, fine and sub-fine analysis. The weak link of energy utilisation is determined. The heating furnace is identified as the lowest exergy efficiency equipment in crude oil gathering and transportation system, which can provide a theoretical basis and scientific method for improving system energy efficiency.

Keywords: 'three box' model; crude oil transportation system; weak link of energy utilisation; heating furnace.
