摘　　要：天然气作为重要的一次能源,产销量逐年递增的同时,也带来日益严重的温室气体排放问题。参考IPCC(联合国政府间气候变化专门委员会)法及中国油气生产企业温室气体核算方法,以气田地面集输系统为研究对象,在分析系统工艺流程特点的基础上,确定温室气体排放计算边界,提出历史排放强度法、工艺流程法两类温室气体排放计算方法,并对重点设备的温室气体排放进行研究。基于Python3.9环境,开发了温室气体排放计算模型,并以某气田地面集输系统为例进行了核算分析,可帮助相关企业快速核算温室气体排放量。最后,基于研究成果对中国气田地面集输系统温室气体排放计算及管理提出了建议。As a vital primary energy,natural gas enjoyed increasing production and sales year by year,which also led to severer problems concerning greenhouse gas emission.According to the methodology by IPCC and greenhouse gas calculation methods of oil and gas production enterprises in China,this paper took the system of gas field surface gathering and transportation as the target to identify the calculation boundary regarding greenhouse gas emission based on the analysis on system process characteristics.Also,it put forward two types of calculation methods in terms of greenhouse gas emission including historical emission intensity method and process method.And the greenhouse gas emission from key equipment was studied herein.On the other hand,a greenhouse gas emission calculation model was developed based on Python3.9 environment.And the calculation analysis was carried out on a certain gas field surface gathering and transportation system,which could help businesses to calculate the greenhouse gas emission at a rapid pace.Finally,suggestions were proposed as regards the calculation and management of greenhouse gas emission by Chinese gas field surface gathering and transportation systems.
