Study on Enhanced oil recovery by steam flooding in heavy oil reservoirs

Abstract

With the development of social economy, the demand for energy is increasing day by day. Under this background, the development of conventional petroleum resources has been unable to meet the needs of social development, and the importance and necessity of exploitation of heavy oil reservoirs has become increasingly prominent. However, the viscosity of heavy oil is larger, the fluidity is worse than that of conventional crude oil, and it is more difficult to exploit. In this regard, in order to further improve the exploitation level of heavy oil reservoir, relevant enterprises and technicians need to strengthen the research on steam flooding exploitation technology, and improve the recovery efficiency of heavy oil reservoir by using the technical advantages of steam flooding. In view of this, this paper first briefly analyzes the mechanism of steam flooding to improve the recovery efficiency of heavy oil reservoirs, and then expounds the main factors affecting the recovery efficiency of steam flooding. On this basis, combined with specific cases, the feasibility of steam flooding to improve the recovery efficiency of heavy oil reservoirs is verified for reference.
