Abstract: To investigate the applicability of water control valves in enhancing liquid rate for oil recovery in offshore edge water reservoirs, a multi-segment well model for horizontal well water control development was constructed using Well B01H in Bohai Sea’s M Oilfield as a case study. Through numerical simulation of reservoirs, a comparative analysis was conducted on inflow control devices (ICDs) and autonomous inflow control devices (AICDs) in terms of the water control and oil enhancement effects, as well as the liquid production profile adjustment mechanisms, during the water-free production period, constant-oil liquid rate enhancement period, and high water-cut period. The research findings indicate that the liquid rate enhancement strategy significantly affects the performance of the water control valve. The ability of the water control valve to regulate the liquid production profile increases as the daily liquid production volume increases. Before the liquid rate enhancement process is completed, the cumulative liquid production volume decreases; after the liquid rate enhancement, the cumulative oil production volume increases. The AICD exhibits phased advantages due to its pressure drop characteristics (the pressure drop during the low water content period is less than that of the ICD, while it surpasses the ICD during the medium to high water content period). In the initial stage of liquid rate enhancement, its water control effect is weaker than that of the ICD. However, in the middle and later stages, its water control and oil production enhancement effect is significantly better than that of the ICD, and this advantage persists until the end of the high water content period. Based on AICD, the optimization design of six horizontal wells is completed, resulting in a cumulative increase in oil production of 7.7% and a cumulative water control rate of 12.2%. This confirms the applicability of AICD in the development of edge water reservoirs. The study reveals the dynamic mechanism of the water control valves, providing a theoretical basis for the efficient development of edge water reservoirs in China’s offshore areas.
