Combined with the correlation of well bottom\|hole pressure and well production rate, the modern production decline analysis can give reservoir properties and single well dynamic reserve through type curve analysis. This method can substitute part functions of well test analysis. After the production data analysis of the field, the modern production decline analysis is applied for all single wells, and several problems are solved for reference. The skin factor, permeability and well dynamic reserve are calculated, which supports gas field later development and well pattern adjustment deploying. The result shows that the Jilake gas condensate field needs well pattern adjustment because of the edge-bottom water drive and the small well control reserve compared to the geologic reserve. Based on the modern production decline analysis and reservoir simulation results, three new producing horizontal wells are drilled, and the dynamic reserve increases dramatically.
Key words： Gas condensate reservoir; Type curve; Dynamic reserve; Blasingame method.
