Abstract: Taking a typical oil transfer station in eastern China as an example in this paper, exergy economics theory in algebraic pattern is applied to the energy system of the oil transfer station on the basis of the exergy analysis. By analysing the cost structure of each equipment and unit, exergy economics equilibrium equation in algebraic pattern can be established. Two different cost allocation methods, extraction method and energy level method, are introduced into the auxiliary equation. Combined with the principle of exergy loss pricing, the unit cost of each exergy loss is calculated. The results show that the energy level method can effectively distinguish the changes of energy quality, which is more suitable for the economic pricing strategy of the oil transfer station gathering and transportation system, and provides a more scientific and effective method and basis for the energy-saving transformation of the oil field gathering and transportation system.

Keywords: crude oil gathering and transportation system; cost structure; cost allocation method; the cost of exergy economics.
