油气田开采流程的甲烷源项分析

Methane Source Term Analysis of Oil and Gas Field Production Process

近年来,世界各国对甲烷减排的重视程度逐渐提高,相应的减排政策也在积极推进。甲烷排放量在国内温室气体排放量的占比较大,因此,实现甲烷减排对于解决温室气体排放具有重要意义。但国内在甲烷减排方面起步相对较晚,目前的核心工作就是全面掌握甲烷排放源的分布状况及其减排能力,为今后出台相应的管控举措做好准备。文章从油气田企业的开采流程开始分析甲烷排放源,把每一个可能产生甲烷的环节一一列举,并且根据甲烷排放源总结了排放特点和排放规律,最终确定了油气田的CH4排放主要来自油气处理部分即油气田联合站,在联合站里天然气处理系统又是主要排放源。

In recent years,the importance of methane emission reduction has been gradually increased in the world,and the corresponding emission reduction policies are actively promoted.Methane emissions account for a large proportion of China’s greenhouse gas emissions,so it is important to achieve methane emission reduction to solve the greenhouse gas emission problem in China.However,China is relatively late in methane emission reduction,and the core task now is to comprehensively grasp the distribution of methane emission sources and their emission reduction capacity,so as to prepare for the introduction of corresponding control measures in the future.This paper analyzes the methane emission sources from the extraction process of oil and gas f ield enterprises,and lists each possible methane generating link,and summarizes the emission characteristics and emission rules according to the methane emission sources.It provides a reference for the direction of methane emission reduction in Chinese oil and gas enterprises.
