Liquid loading is a common phenomenon during production in tight gas field of Daniudi area, and it seriously affects the normal production of gas wells. Accurate prediction and judgment of the liquid loading of gas wells will provide theoretical basis for dewatering measures. This paper judged the liquid loading of gas wells by using critical slip density method. The result shows that this method can be used to judge the liquid loading of gas wells accurately, and the judgment result is consistent with engineering practice. The method also shows that the gas well will not accumulate liquid immediately except slipping exceeding a certain degree.
