- 摘要:
- 为实现“双碳”目标,油气田企业加快绿色转型发展,推进低碳化油气生产。热能是油气单井低温位燃气加热炉和电磁加热器清洁替代的主要方向,但存在热泵种类众多、技术混杂以及北方低温环境适应性较差等问题。开展跨临界CO2热泵和电磁加热器应用对比试验。试验结果表明,跨临界CO2热泵运行的性能系数(COP )达到2.99,节电率＞62%,预计全年COP 可达3.5左右,相较于电磁加热器减少运行能源费10.23万元/a,减碳量约215.6 t/a;跨临界CO2热泵低温适应性强,可智能操控,运行安全稳定,宽温域加热应用前景广泛。在油田单井应用跨临界CO2热泵技术具有较好的经济效益和社会效益，可为类似工程提供参考。
To realize the “dual carbon” goal, oil and gas field companies are accelerating their green transformation and promoting low-carbon oil and gas production. Heat is the primary focus for clean replacement of low-temperature gas heating furnaces and electromagnetic heaters in oil and gas single wells. However, challenges include a wide variety of heat pumps, diverse technologies, and poor adaptability to low temperature in northern regions. To address this, a comparative application test of transcritical CO2 heat pumps and electromagnetic heaters was carried out. Test results indicate that the transcritical CO2 heat pump achieved a coefficient of performance(COP ) of 2.99, with an energy-saving rate exceeding 62%. It is expected that the annual operating COP can reach about 3.5. Compared with the electromagnetic heater, the annual operating energy cost is reduced by 102 300 yuan, and the carbon emission are reduced by about 215.6 tons. Moreover, the transcritical CO2 heat pump exhibits strong adaptability to low temperatures, intelligent control, safe and stable operation, and broad application prospects across a wide temperature range, offering significant economic and social benefits and providing reference for projects of the same nature.
