大斜度气井临界携液产量预测新方法

摘要

It's well known that the models of critical liquid carrying flow rate for gas well are all based on the vertical well, without considering the angle of inclination.Based on the moving character of liquid drop in highly deviated gas well, formula to estimate the critical liquid carrying flow rate has been derived through correcting Turner model by considering the angle of inclination, and the correction factor is given for Turner formula.%目前广泛应用的天然气临界产量计算模型都是建立在直井的基础上,没有考虑井斜角对携液的影响.根据大斜度天然气井中液滴运动特点,以应用最普遍的Turner模型为基础,考虑井斜角的影响对Turner模型进行了修正,推导出大斜度气井临界携液产量预测公式,并给出了Turner公式修正系数.
