摘　　要：由于凝析气藏流体性质的特殊性,反凝析和气液分离常常造成井筒积液,严重影响气井产能。利用塔河凝析气井井筒积液前后的生产动态变化,求出了判断气井是否积液的临界动能因子,由此进一步计算出了各区块井的临界流量,并与李闽公式计算的结果和现场实际进行了对比,在此基础上结合实测流压梯度曲线,提出了塔河凝析气井井筒积液的判断标准。Owing to the special fluid property, the retrograde condensation and gas-liquid separation of condensate gas reservoir often cause the wellbore liquid loading, which seriously affects the production capacity of gas well. This paper works out the critical kinetic energy factor to judge the liquid loading of condensate gas well by using the production performance change in condensate gas well of Tahe Oilfield, finding out the critical flow in each block compared with the results of Limin formula calculation and field measurement. Based on this, the diagnosing criterion is proposed combined with the flowing pressure gradient eurve.
