中海油W油田群基于一种碳排模型的分析与计算

Analysis and Calculation of a Carbon Emission Model in CNOOC W Oilfield Group

为应对气候变化和保护环境,中国宣布了"碳达峰、碳中和"等国家自主贡献新目标。中海油W油田群积极响应政策,提前探索生产过程中产生的碳排放,通过定量分析,为后期制定减少碳排放措施提前打好基础。在油气开采的过程中会产生CO_(2)等温室气体,经分析,油田温室气体的排放类别可分为:化石燃料燃烧、火炬燃烧、电力供给、工艺过程排放四部分。文章是基于一种碳排模型,分析产生碳排放的环节,预估油田群的碳排放量约为每年22万吨CO_(2)。

To address climate change and protect the environment, China has announced new targets for its nationally determined contributions, including carbon peak and carbon neutrality. CNOOC W oilfield group actively responded to the policy and explored the carbon emissions generated in the production process in advance. Through quantitative analysis, it laid a foundation for the development of measures to reduce carbon emissions in advance. CO_(2) and other greenhouse gases will be produced in the process of oil and gas exploitation. According to the analysis, the emission of greenhouse gases in oil fields can be divided into four parts:fossil fuel combustion, torch combustion, power supply and technological process emissions. Based on a carbon emission model,this paper analyzes the links that produce carbon emissions, and estimates that the carbon emissions of equipment or facilities are about 220 000 tons CO_(2) per year.
