According to the phase character,a gas condensate well undergoing depletion consists of three regions: a region containing single phase reservoir gas,a region of condense buildup where only gas is flowing,an inner near-wellbore region where both gas and oil flow simultaneously.

It is needed to simulate the flow state and the pressure distribution of the gas reservoir accurately to predict the production performance and the economic benefits for the condensate reservoir,which was almost not considered in the process of performance simulation for the borehole of condensate wells before.

Gas injection is a practical and feasible development way to improve the recovery factor,can eliminate the pollution from retrograde condensate and reverse imbibitions in the zones near the borehole effectively to improve the productivity of condensate wells,and has important effects for stable production and retrograde condensate of condensate wells and gas wells with low permeability.

In gas-condensate wells, reservoirs are easily contaminated by lost well control fluid during workover.
