油田站场采出水存在大量40~60 ℃的低温余热,为响应国家“节能减排”的号召,考虑对油田采出水余热进行回收利用,但油田采出水余热不能利用直接换热方式将原油加热到65 ℃以上,需要采用热泵提升温度。结合油田站场具体的工程技术条件,通过对压缩式热泵和吸收式热泵进行技术和经济分析,得出两种热泵技术及经济方案比选的研究结果。研究结果表明，可以通过热泵提取油田采出水余热对原油进行加热，取代加热炉,但需要根据具体的边界条件，确定应用的热泵类型。

There is a large amount of low temperature waste heat of 40~60 ℃ in oil field site stations. In response to the country wide call for “Energy Conservation and Emission Reduction” initiative, it is considered to recycle the waste heat recovered from oil field produced water. However, the waste heat from oil field produced water cannot heat the crude oil to above 65 ℃ via direct heat transfer. Therefore, heat pumps are needed to raise the temperature. Taking into consideration the site specific conditions and engineering technology of the station, the research conclusions of compression heat pump and absorption heat pump option selection in terms of technical and economic aspects can be drawn through the technical and economic analysis of these two types heat pumps. To conclude, it is feasible to replace the heat furnace in oil field site station with heat pump. This paper could be used as a reference for the engineering design of heat pumps.
