Abstract

In this paper, in view of the development problems of high-temperature and high-pressure reservoirs, the application optimization strategies of carbon dioxide flooding enhanced oil recovery technology are systematically discussed. Through the analysis of the characteristics of high-temperature and high-pressure reservoirs and the mechanism of carbon dioxide flooding, combined with numerical simulation and field practice cases, the influence of key parameters such as gas injection pressure, injection rate, injection volume, and CO₂ concentration on the oil displacement effect was deeply studied. This paper proposes a comprehensive application scheme that optimizes injection-production well pattern, innovates wellbore insulation technology and combines other stimulation technologies to provide theoretical basis and practical guidance for the efficient development of high-temperature and high-pressure reservoirs.
