PROCEDURE FOR PREDICTING THE INDICES OF DEVELOPMENT OF DEEP-SEATED GAS–CONDENSATE RESERVOIRS IN A DEPLETION REGIME FROM WELLHEAD DATA

By simultaneous solution of the equation of infl ow of a gas–condensate mixture in the formation and in the tube and with account taken of the phase states of the gas–condensate mixture, the author has implemented a calculation procedure that makes it possible to predict, from wellhead data, the pressure at the wellbore and the formation pressure, and also other technological indices of development of deep-seated gas–condensate reservoirs in a depletion regime. Within the limits of the considered initial data, the author has modeled the process of infl ow of the gas–condensate mixture to a partially penetrating well in a homogeneous anisotropic formation and has established the regularities of infl uence of the site of drilling-in and the degree of imperfection of the accumulation of a retrograde condensate in near-wellbore zones with time.
