油田加热炉生产碳排放影响因素分析

Analysis of Factors Affecting Carbon Emissions in Oilfield Heating Furnace Production

加热炉是油田生产能耗与碳排放的主要设备之一,其生产过程中的碳排放是油田企业碳排放核算不可忽视的部分,直接影响油田的整体经济效益和社会效益。基于物料衡算法及《中国石油天然气生产企业温室气体排放核算方法与报告指南》,建立油田加热炉碳排放核算模型;根据油田加热炉生产碳排放监测数据,基于加热炉效率定性及定量分析了负荷率、排烟温度、热效率、过剩空气系数、环表温差、炉膛内压等因素对加热炉生产碳排放的影响;通过分析加热炉生产过程中的生产要求、燃料性质、加热炉效率,发现加热炉效率是影响加热炉生产碳排放的关键可操作因素。对油田加热炉生产碳排放影响因素进行分析,可为油田生产碳核查与碳评价提供参考依据,助力“绿色油田”的建设。

A heating furnace is one of the main equipment for energy consumption and carbon emissions in oilfield production.The carbon emissions during its production process are an indispensable part of the carbon emission accounting of oilfield enterprises,directly affecting the overall economic and social benefits of the oilfield.A carbon emission accounting model for oilfield heating furnaces is established based on the material balance algorithm and the Accounting Methods and Reporting Guidelines for Greenhouse Gas Emissions of Chinese Petroleum and Natural Gas Production Enterprises.Based on the monitoring data of carbon emissions from oilfield heating furnace production,the effects of load rate,exhaust gas temperature,thermal efficiency,excess air coefficient,environment and surface temperature difference,and furnace internal pressure on carbon emissions from heating furnace production are qualitatively and quantitatively analyzed based on heating furnace efficiency.The impacts of production requirements,fuel properties,and furnace efficiency on carbon emissions during the production process of heating furnaces are analyzed.Among them,heating furnace efficiency is a key operational factor that affects carbon emissions in heating furnace production.The analysis of factors affecting carbon emissions from oilfield heating furnace production provides a reference basis for carbon verification and evaluation in oilfield production,and assists in the construction of"green oilfields".
