Modelling the Effect of Compositional Changes in Transient Flow of Gas Condensate Reservoirs
要約
This paper considers the flow behavior in gas condensate reservoir and presents an approach for calculating the pressure depletion performance of a gas condensate reservoir from the original reservoir fluid composition using the vapor-liquid equilibrium calculations, the fluid properties and retrograde liquid accumulation as guides. The results correspond to drawdown analysis of a condensate reservoir where flow of the phases occurs and comparison with other standard work on transient pressure analysis of gas condensate reservoirs was satisfactory. A principal use of the method would be for the initial estimation of pressure depletion pattern after discovery of a gas condensate reservoir, where the compositional analysis of the reservoir fluid may be only approximate and the dew point if not known, is assumed to be the reservoir temperature and pressure. It is also a valuable tool during the production period for reservoir surveillance and monitoring.
