Study on the Behavior of a Well Control Emergency Diverter Engaging with a Gas Flow Under Different Parameters

With the advancement of oil and gas extraction technologies, particularly in the development of deep and ultra-deep unconventional resources, the demand for well control emergency response technologies has become increasingly urgent. The deepening of oil and gas resource development has increased the risk of sudden accidents such as blowouts, and the complexity of emerging operational environments has placed higher demands on emergency response techniques. This paper focuses on diverter technology in well control emergency response. It specifically analyzes the influence of key parameters—such as the diverter’s engagement flow velocity, descent velocity, and relative distance to the wellhead during deployment for high-temperature gas diversion at a blowout site—on the surrounding temperature field, pressure field, and the jet impact force exerted on the diverter upon engagement. Based on this analysis, the optimal engagement flow velocity is identified as 0.5–0.8 m/s. The findings provide a scientific basis for further optimizing the deployment procedure and enhancing the efficiency and safety of blowout response operations. Meanwhile, This study holds significant importance for promoting the standardization of well control technology.
