摘要
我国南海东方气田终端可动用的CO2储量相当丰富,如何将这些CO2埋存减排成为很重要的问题。针对东方终端的具体情况,提出了就地陆上或海上埋存与注入涠洲油田或渤海油田提高采收率的四种资源化利用途径,在此基础上提出了四种集CO2处理、液化、输送、储存和埋存为一体的利用方案。针对每种方案,开展了工艺计算、设备选型以及经济分析,模拟结果认为方案一(东方终端就地埋存CO2处理)投资费用最低,但没有经济效益;方案四[渤海NB 35-2附近提高石油采收率(EOR)或提高气体采收率(EGR)]投资费用最高;方案二(东方1-1平台EGR)的投资费用低于方案三(涠洲12-1平台EGR或EOR)。EGR/EOR都会产生收益,最终方案的选取还需根据收益进行经济评价分析。
The available CO_2 volume in Dongfang gas reservoir is rather abundant,which brings an important problem,that is,how to bury the CO_2 to realize CO_2 emission reduction.According to the specific situation of Dongfang gas field terminal,four schemes to recycle CO_2 are proposed,including burying on site onshore or offshore and injecting in Weizhou oil field or Bohai oil field for enhancing oil recovery(EOR).On that basis,four utilization programs,all of which include treatment,liquefaction,transportation and burying of CO_2,are put forward.Finally,process calculation,apparatus selection and economic analysis are developed for every scheme.Results show that the first scheme(onshore local storage near Dongfang gas field terminal)possesses the least investment,but no profit.The fourth scheme[EOR/enhancing gas recovery(EOR/EGR)in Bohai Gulf]takes the largest investment.The investment of the second scheme(EGR in Dongfang 1-1 gas field)is less than that of the third scheme(EGR/EOR in Weizhou 12-1 platform).EGR/EOR can always get profit.The optimum scheme should be determined by economic evaluation.
