摘　　要：凝析气藏由于其流体性质的特殊性,在产能试井中遇到很多新的问题。针对常出现的压力恢复压力下降及解释中的表皮系数异常偏大等问题,提出了针对凝析气藏的修正等时试井方法。经过现场测试,取得了较好的效果。Many new problems appear during deliverability test in condensate gas reservoirs due to the specific characteristics of the fluid in them,examples are pressure decreases in build-up period,calculated skin factor is often very high etc.This paper proposes a new modified isochronal test method which is applicable in condensate gas reservoirs.Field practice has verified that this method is good.
