Abstract: Using the abundant field data from Banqiao condensate gas reservoir, the unflowing pressure, unflowing production and their relationship for condensate gas well are studied, the applicable experiential formulae are given, by which the abandon production and abandon pressure for the condensate gas well or reservoir are predicted. And the more precise recoverable reserves of the condensate gas reservoir can also be predicted. These provide solid bases for efficient development, reserves management and exploitation planning of such a reservoir.

Key words: condensate gas reservoir, gas well, pressure, production, recovery factor, recoverable reserve
