摘要： 地热是一种清洁的可再生能源,随着传统能源的日益枯竭和人类对环境保护的意识增强,进入中高含水期后的油田在油气生产中携带的大量热能受到了人们的重视。论文以松辽盆地北部的大庆油田为例,根据含油气沉积盆地中地下赋存的载体不同将地热资源分为纯地下水型和油田产出水型地热资源两种。通过分析热源的形成机制,调查油田产出水型地热资源的利用现状,统计出大庆油田年油田产出水量为3.98×108 m3,按照利用10 ℃温差的热能计算,相当于56.95×104 t标准煤的能量,潜力十分巨大,并比较了油田产出水型地热资源热泵供暖与传统锅炉供暖的设备成本和运行费用,以15 a为周期稳定运行可以节约572×104元,经济效益也较为可观,而且地热资源清洁、环保、可循环利用,在油田实际生产中可广泛应用于生活设施等建筑的供暖,以及原油集输伴热等流程中。

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
