According to the production process characteristics of transit crude oil depot, the evaluation model for the major energy-using equipment in crude oil depot was established. According to the law for energy conservation and transformation, the energy balance equation for crude oil depot was established. Six evaluation energy level depot indicators, including the energy efficiency, heat energy efficiency, electricity energy efficiency, power consumption for the transport of unit oil, and gas consumption for the transport of unit oil, the comprehensive energy consumption for the transport of unit oil were proposed. On the basis, the energy using status for a transit crude oil depot in the oil filed was evaluated. The result shows that, the overall energy utilization level of transit crude oil storage can be reflected by energy efficiency. The energy efficiency analysis for crude oil storage is helpful to determine the energy weaknesses and is contribute to point out the direction to improve the energy level.
