Research on stimulation of injection and production capacity for single well in underground gas storage

Underground gas storage is the best choice for natural resource reserve and peak value. Storage capacity of underground single well injection production are key indicators shaving capacity. This paper focuses on research expansion stimulation a basin in Western China. Firstly, based study two-phase seepage law water, numerical simulation model coupling high velocity non-Darcy effect gas-water two phase established; Secondly, influencing factors analysed. Finally, acidizing can effectively improve well. The result shows that differential pressure reduced by 70%, volume increased 14.8% 26.9%.
