英文摘要：

In this paper,the situations of crude oil heating and oily water utilization were analyzed. The development situation of solar heat pump at home and abroad was introduced. It was put forward that the solar-assisted sewage source heat pump system could be used to reuse oily water for crude oil heating. The composition of the system and five kinds of operation mode were analyzed. The mathematical model was also established. It provided some references for the application of solar-assisted sewage source heat pump system.
