摘要
凝析气井产能试井中,由于诸多因素影响,修正等时试井按常规方法处理常出现产能曲线为负的异常情况。鉴于此,基于变表皮系数理论与二项式产能方程理论,将变表皮系数引入凝析气井产能试井解释中,并对其产量进行校正,对异常产能曲线进行修正。实例应用表明该方法正确可行。
During the gas condensate well test, the slope of deliverability curve will be affected by many factors and always becomes negative when using the conventional well modified isochronal test curve. For this reason, based on the changing-factor skin theory and deliverability equation, the paper takes the changing-skin factors into the gas-condensate well test interpreting, then the abnormal deliverability curve can be modified. The case study also shows the feasibility of the method.
