Abstract
Producing gas condensate reservoirs with pressure depletion will cause condensate oil accumulating at Near-well district as pres sure bellows dew-point pressure, which will decreasing permeability and deliverability. Research the distribution of condensate oil assembling near-well is very important for evaluating deliverability of gas condensate reservoirs. Based on theory of substance balance and fluid mechanics in porous medium, deduced a new extend model account for three-regions changes of gas condensate reservoirs, application of which shows it is significant for evaluating gas condensate deliverability by its three-regions enlarging and reducing rule.
