China urgently requires clean and efficient coal utilization as one of the world’s largest coal consumers. Underground Coal Gasification (UCG) offers a promising solution by converting deep coal seams into syngas through the injection of gasification agents. This study introduces a novel approach by incorporating well types traditionally used in oil and gas field development into the UCG process. Specifically, the research evaluates the effectiveness of various well setups, including vertical and horizontal well combinations and the CRIP method. Additionally, it investigates the impact of key gasification parameters, such as injection pressure, gasification agent composition, and well spacing, on UCG performance. The results show that incorporating water into the gasification process enhances the calorific value of the syngas, though excessive water can lower operational temperatures or even halt gasification. Moreover, both overly large and small well spacing and injection pressures negatively affect the production of high-calorie syngas and efficient coal utilization. Among the methods tested, the CRIP method demonstrated the highest overall efficiency, while the horizontal injection well-horizontal production well configuration proved optimal for rapid coal seam development. These findings offer valuable insights for optimizing UCG processes and maximizing coal resource utilization.
