Well control reserve is crucial in the development of gas reservoir. Due to the large heterogeneity in volcanic gas reservoir,the calculation of dynamic reserve should take its storage-perforation model as well as threshold pressure into consideration. Based on flow analysis,increase of dynamic reserve can be separated into two stages: the stages before and upon pseudo-steady state flow. The mathematical model is built for predicting the dynamic reserve of volcanic gas reservoir. Take well Xushen 1-1 as an example,through comparison of well testing and model calculation,the validity of mathematical model is verified. Furthermore,the change of well control reserve with time is provided,which is more helpful for determining dynamic reserve and directing the development of volcanic gas reservoir.
