Abstract: Geotherm is a clean and renewable energy. With the increasing of traditional energy sources depletion and enhancing of human awareness to environmental protection, the huge heat energy carried by oil and gas production of middle or high water cut oilfield draws much attention. This paper takes Daqing Oilfield in the northern Songliao Basin for example, and divides the geothermal resources into pure underground water and oilfield produced water based on different vectors of geothermal resources in sedimentary basins with oil and gas. By analyzing the formation mechanism of the heat source, investigating current utilization of oilfield production water, the amount of oilfield production water in Daqing oilfield is 3.98×108 m3 every year, equivalent to 56.95×104 t standard coal in using 10 ℃ range of temperature terms, and has huge potential. By comparing the equipment and operating costs between heat pump heating used oilfield production water and traditional boiler heating, 572×104 yuan are saved in 15 years by stable running, and the economic benefits are also considerable, and furthermore, geothermal resource can be reused to heat buildings of oilfield production and living facilities, as well as heat for crude oil gathering and transportation such as clean, environmental and recycling.

Key words: geothermal resource, oilfield production water, sedimentary basin, heat pump, circular utilization
