Gas Condensate Reservoir Well Test Analysis And Interpretation Method Research

On the basis of the deeply understanding of gas condensates reservoir flow characteristic and gas well exploitation behavior, aimed at the different flow characteristic between the early , middle period in gas condensate reservoir exploitation, while, take notice of the severity interfere in wellbore during pressure build-up period of gas well, this paper developed several flow mathematical model, such as homogeneous infinite formation model, homogeneous infinite formation model which comprise variable wellbore storage, homogeneous compositive model which consists of two flow regions, and consists of three flow regions. Thus reflect the various pressure behavior during gas well testing, also satisfy the need of gas condensate welltesting interpretation; then, developed practicality welltesting interpretation metheds study of gas condensate, which take account of the oil-gas or oil-gas-water multiple phases flow effects, and parameters estimation of gas condensate welltesting interpretation; finally, made the theory research results into the gas welltesting interpretation software.
