Abstract
Carbonated water flooding (CWF), as an emerging enhanced oil recovery technology, holds significant importance in oilfield development. This paper explores the basic principles and mechanisms of CWF, experimental and simulation studies, field applications, advantages, and challenges, as well as its technological development and future outlook. First, the definition and research background of CWF is introduced, highlighting its unique advantages in improving oil mobility and displacement efficiency. Second, the progress of experimental and simulation research both domestically and internationally is analyzed, demonstrating the adaptability and effectiveness of CWF under different geological conditions. Then, through multiple case studies, the effects of CWF in practical applications are discussed, summarizing the successful experiences and lessons learned from failures. Although CWF shows significant advantages in environmental protection and enhanced oil recovery, it still faces challenges in CO2 capture and transportation, formation reactions and corrosion issues, and economic feasibility. Finally, the development direction and industrial prospects of CWF technology are anticipated, with suggestions for further research and practical application. This paper aims to provide systematic reference and guidance for researchers and engineers in related fields, promoting the in-depth study and widespread application of CWF technology.
