Inflow dynamic curve of condensate well reflects fluid supply capacity from condensate gas reservoir to production well.Studying inflow dynamic curve of condensate gas reservoir may present optimization design of production parameter better and improve ultimate recovery of condensate reservoir.In allusion to percolation characteristics in condensate gas reservoir No.3 block under different bottom hole flowing pressure,inflow dynamic mathematical model for condensate gas well of uniform function relationship is established by reasoning,correlative calculation program is worked out,and example calculation and characteristic analysis of inflow dynamic curve are done.The research results show that inflow dynamic curve equation of condensate gas well under different bottom hole flowing pressure is a continuous function regarding formation original pressure,dew point pressure,and critical flow pressure as endpoint.After considering related influencing factors,mathematical model established by reasoning adapts to the reality better.
