Productivity equation for condensate gas well

YUAN Shusheng1,DUAN YongGang1,YANG Yu2(1.College of Petroleum Engineering,Southwest Petroleum University,Chengdu 610500,China;2.Southwest Oil Gas Company,Sinopec,Chengdu 610042,China)  
In the course of condensate reservoir development,with the decline of formation pressure,the retrograde condensate oil will be accumulated near the bottom hole,which will damage the formation permeability.Based on the flow character of natural gas and the petro-condensate liquid in the formation,combining phase state theory with flow mechanism of condensate gas.At the same time,the change of the liquid phase and the components and the various skin factors and flow regime character under different condition are also considered.The two-phase pseudo-pressure function of stable state theory is used.A new way is adopted to analysze the deliverability of condensate gas well.For these methods and concepts,the mathematical model for three different situations: First,only gas single-phase flows without condensate oil.Second,only gas single-phase flows when condensate oil appear.Last,gas and condensate oil two-phase flows in condensate gas well.The new method is suitable for the forecast of the deliverability in condensate well.
