油田注汽锅炉综合能耗与温室气体排放特性研究

Research on Comprehensive Energy Consumption and Greenhouse Gas Emission Characteristics of Steam Generators Used in Oil-fields

随着“双碳”目标的提出,温室气体排放成为研究热点。从油田注汽锅炉运行参数出发,基于我国现有标准规范及IPCC2006温室气体排放核算模型,对油田注汽锅炉运行过程的综合能耗及温室气体排放特性进行研究。结果表明:使用气体燃料时油田注汽锅炉的综合能耗和温室气体排放强度最低,分别为85 kgce/t和144 kg_(CO_(2))/t;使用固体燃料时油田注汽锅炉的综合能耗和温室气体排放强度最高,分别为108 kgce/t和279 kg_(CO_(2))/t。通过提高油田注汽锅炉的热效率、优化稠油开采工艺等措施可以降低锅炉综合能耗与温室气体排放强度。

With the proposal of the "dual carbon" goal,greenhouse gas emissions have become a research hotspot.From the operating parameters of steam generators used in oil-fields,and based on the existing standards and regulations in China and the IPCC2006 greenhouse gas emission accounting model,the comprehensive energy consumption and greenhouse gas emission characteristics of the operation process of steam generators used in oil-fields have been studied.The results show that the comprehensive energy consumption and greenhouse gas emission intensity of studies the comprehensive energy consumption and greenhouse gas emission characteristics of the operation process of steam generators used in oil-fields are the lowest when using gas fuels,at 85 kgce/t and 144 kg_(CO_(2))/t,respectively;When using solid fuels,the comprehensive energy consumption and greenhouse gas emission intensity of steam generators used in oil-fields are the highest,at 108 kgce/t and 279 kg_(CO_(2))/t,respectively.By improving the thermal efficiency of steam generators used in oil-fields and optimizing heavy oil extraction processes,the comprehensive energy consumption and greenhouse gas emission intensity of boilers can be reduced.
