由于原油价格持续走高、美国常规原油产量持续下降和对温室气体排放的关注,人们对CO2EOR技术重新产生了兴趣。该技术面临的挑战在于是否可以获得足够量的CO2,基础设施能否满足要求,以及CO2的成本是不是足够低。对1673个潜在CO2EOR的候选油藏进行了分析。为了确定CO2的可利用性,图示了EOR候选油藏沿线的天然和工业CO2资源。工业CO2运输到生产现场其成本包括收集成本和管线运输费,由此可以确定EOR项目的经济性和开发情况。分析表明,如果通过大规模地收集和购买工业源CO2增加CO2的供应量,并且油价在$45～60/bbl之间,可以实现CO2EOR日增油1.2×106bbl和日埋存CO2300×106t。
There has been renewed interest in CO2EOR technology as crude oil prices continue to rise, the United States continues to see declines in conventional crude oil production and concerns about greenhouse gas emissions. The challenge for this technology is whether sufficient quantities of CO2 are available, whether the infrastructure meets the requirements, and whether the cost of CO2 is low enough. The 1673 potential CO2EOR candidate reservoirs were analyzed. In order to determine the availability of CO2, natural and industrial CO2 resources along the EOR candidate reservoir are illustrated. The cost of transporting industrial CO2 to the production site includes the cost of collection and the cost of transporting the pipeline, which will determine the economics and development of the EOR project. The analysis shows that CO2 can be increased by 1.2 × 106bbl per day and CO2300 × 106t per day if CO2 is increased by large-scale collection and purchase of industrial sources of CO2 and oil prices between $ 45-60 / bbl.
