对地热资源、LNG和热泵技术替代油田燃油加热炉工艺可行性进行充分研究，并对3种技术替代油田燃油加热炉后的经济效益和环保效益进行分析。通过研究和分析得出，地热资源、LNG和热泵技术是进行油田加热炉燃油替代的有效途径，LNG替代燃油后的运行费用可降低30%、热泵可降低45%，地热水可降低65%。通过加热炉燃油替代，不但可以获得可观的经济效益，还可以有效降低颗粒物、SO₂以及NO_x等污染物的排放。

The technology feasibility using geothermal resources,LNG and heat pump technology to replace fuel oil for heating furnace in oilfields is adequately studied and the economic and environmental benefits after substitution by these three technologies are analyzed separately.Based on the study and analysis,it is found that the geothermal resources,LNG and heat pump technology are effective ways to replace fuel oil for heating furnace in oilfield.The substitutions of LNG,heat pump and geothermal water can cut down the operating expenses by 30%,45% and 65%.Through replacing the fuel oil for heating furnace,considerable economic benefit can be gained,and the emission of pollutants such as particulate matters,SO₂ and NO_x can be effectively reduced.
