The dynamic reserve of gas well is very important to allocate reasonable production and draw up development programs. However, due to low permeability and strong heterogeneity of low permeability gas reservoir, it is hard to calculate the dynamic reserve correctly. Combined with dynamic production data of low permeability gas reservoir, through statistical analysis, the production index curves of single wells were divided into three types: standard type, fluctuation type, multi-section type, and the characteristics of production index curve of single wells and the related reasons were analyzed. Finally, the method for determining dynamic reserve of different wells based on flowing material balance method was proposed. The case study shows that it is reasonable that using flowing material balance method to calculate the single well dynamic reserves of low permeability gas reservoir.
