摘要：CO2 near-miscible flooding was proposed for the development of the newly discovered offshore Qinhuangdao oilfield. However, different with miscible flooding, the near-miscible flooding corresponds to a region instead of a point (MMP). This paper focuses on the determination of the lower and upper boundaries of the near-miscible area. Based on the data of PVT test, a compositional model was established and fitted. Then slim tube simulation and empirical equation were conducted to obtain the minimum near-miscible pressure (MNMP). The results can provide valuable guidance for the effective development of the targeted offshore oilfield.
