Abstract: To ensure the realization of carbon peaking and carbon neutrality goals，energy conservation is the most cost-effective means. Oilfield enterprises are characterized by scattered production facilities，long process flow and extensive coverage of oil areas. The challenges they face in energy conservation management are reflected in the following aspects：the energy consumption measure- ment boundary is unclear，leading to the difficulty in identifying the subject to assume responsibilities；the monthly energy statistics is reported manually level by level，resulting in relatively lagged control of energy consumption；energy efficiency is evaluated by the sam- pling tests of testing agencies，which fails to achieve a whole coverage；energy-conservative measures are judged by individual experi- ence，lacking timeliness and effect tracking. With the development of the internet of things in oilfield enterprises，the automatic percep- tion ability of the production site and the information processing ability of the data background are enhanced continually. It has become a new proposition to improve energy efficiency，reduce energy consumption and realize fine and efficient energy conservation in the whole process of production. This paper summarizes the innovative practice of applying information technology to carry out energy- conservative business in domestic petroleum industry，and puts forward the practical path for implementing the digital transformation of energy conservation management in oilfield enterprises.

摘要： 落实“双碳”目标，节能是最经济有效的手段。油田企业具有生产设施分散、工艺流程长、油区面积广的特点。节能管理的难点体现在能耗计量边界不清，难以落实责任；能源统计依赖人工层级上报月度报表，能耗管控相对滞后；能效评价通过检测机构抽测，无法覆盖全面；节能措施通过人工经验判断，缺少时效性和效果跟踪等方面。随着油田企业物联网的建设，生产现场的自动感知能力和数据后台的信息处理能力持续增强，面向生产全过程提能效、降能耗，实现精细、高效节能成为新命题。总结了国内石油行业应用信息技术开展节能业务的创新实践，提出了油田企业实施节能管理数字化转型的实践路径。
