Abstract

Different drilling methods have great influence on the performance of gas-condensate reservoir.Gas drilling tends to cause retrograde condensation phenomenon owing to lower bottom hole pressure.It is of great significance to conduct the research of retrograde condensation phenomenon and its effects on reservoir.Annulus pressure distribution and reservoir pressure distribution near wellbore during gas drilling are analyzed.The retrograde condensation behavior in reservoir is researched.The impact of retrograde condensation behavior on gas drilling and completion is discussed in this article.The results show that retrograde condensation and evaporation phenomenon will occur when gas-condensate reservoirs are drilled by gas and retrograde condensation phenomenon gradually expands outwards as drilling process goes on.Mixed emulsification zone and condensation fluid zone caused by retrograde condensation phenomenon can be formed in well completion process.The retrograde condensation behavior can prevent operating fluid invading reservoir by fluid-blocking effect and wetting reverse which can alter the direction of capillary force during well completion,and alleviate reservoir damage.
