Гидродинамические исследования газоконденсатных скважин (ГДИ) позволяют определить особенности фильтрации флюидов в газоконденсатном пласте по кривым восстановления давления (КВД). Изменение формы КВД может отражать поведение флюидов в пласте, то есть характер движения жидкости и газа в пористой среде. Показана возможность определения по КВД характеристик зоны совместной фильтрации жид-кости и газа, а также радиуса зоны газоконденсатной блокады. На примерах билогарифмического графика кривой восстановления давления месторождений Венесуэллы и России показано существование участка характерной формы на КВД, свидетельствующего о ретроградных процессах, происходящих в пласте.

Hydrodynamic studies in gas-condensate wells allow determining the features of fluids flow in the gas condensate reservoir by build-up curves. A variation in the shape of the build-up curve may reflect a behavior of fluids in the reservoir, that is the nature of the fluids motion in porous media. The possibility of identification of characteristics of the combined liquid and gas filtration zone by build-up curves, as well as the radius of the zone of gas-condensate blockage is shown. Based on the examples of the log-log build-up graph in Venezuelan and Russian fields the exis-tence of the characteristic shape part on the build-up curves was demonstrated, evidencing the retrograde processes occurring in the reservoir.
