W a ter v apour in Gas condensate reservo ir has an e ffect
on the phase behav io r of the Gas condensa te system.
Re trog rade condensation w ill occur in the wa ter vapour
conta ined Gas condensate sy stem when fo rm ation pressure
declines at a constant tem petu re. Condensate o il and
condensate w ater w ill em erge in Re trog rade condensation.
Accumu lation of Condensate liqu id w ill produce se rious loss
o f o il w e ll productiv ity. There fo re, to avo id produc ing
condensate liqu id is the key m easure to im prove o il recovery.
In Research to the w ate r vapour con tained Gas condensate
system, w e summ ar ized the phase behav ior o f the Gas
condensate system. A t the sam e tim e, w e conduct the
simu la tion o f the w ater vapour conta ined Gas condensate
system under the two cond itions: w ater vapour is considered o r
not, on the basis o f experim ent resu lt ana lys is o f som e wa ter
vapour conta ined Gas condensate system. The simu la tion
resu lt is cons isten tw ith the experim ent result analysis.
