Optimization and Application of Supercritical CO2 Displacement Technology in Late Development of Heavy Oil Field
Explored the application and optimization of supercritical CO2 displacement technology in the later development of heavy oil fields.By comparing the geological characteristics,reservoir properties,and recovery rates before and after displacement of P oilfield,it was found that this technology significantly improved the recovery rate,increasing from 10%-15%to 30%-45%,and daily production increased by 30%-50%.In addition,CO2 displacement also has significant environmental benefits,as it can sequester 50%-75%of injected CO2,reduce greenhouse gas emissions,and have impacts on oil fields and surrounding environments,including reducing air pollution and protecting ecosystems.Research has shown that supercritical CO2 displacement technology not only improves heavy oil recovery,but also has good environmental protection advantages.
