摘　　要：迪那2深层异常高压凝析气藏,井口压力动态监测出现资料异常现象。在拟合迪那2气田井筒温度剖面基础上,推导了考虑相态变化、动态摩阻和动能损耗等因素的压力折算新公式,并编制了相应的计算软件,得到了更为完善的异常高压凝析气井井筒动态分析方法。实例验证表明,该模型可靠程度较高,适用性较好。Dina-2 gas field is a deep and abnormal high pressure condensate reservoir, and the pressure behavior monitoring in wellhead results in an abnormal occurrence. According to the wellbore temperature profile, this paper presents new reduced pressure formula considering phase behavior change, dynamic friction coefficient and kinetic energy loss, and develops the corresponding software, obtaining more perfect performance analysis method for abnormal high pressure condensate gas well. The case study shows the model is of high reliability and practicability.
