摘　　要：水平井开发技术作为提高采收率的重要手段,在苏里格气田逐渐进行规模实施。在气藏水平井的生产过程中,当气体不能将产出的液体连续携带出井口时,水平井井筒中将产生积液,积液将增加对气层的回压,严重限制气井的产能,甚至会造成气井"水淹",影响气井的正常生产。在直井连续携液模型研究的基础上,采用角度相关李闽连续携液理论,确定了苏里格气田水平井临界携液产量,结合苏里格气田水平井的单井生产动态,验证了该方法在苏里格气田水平井临界携液产量计算上的适用性和准确性,对鄂尔多斯盆地苏里格气田水平井的生产具有重要指导意义。Technology of horizontal well development,as an important means of enhancing oil recovery,is gradually large scale implemented in Sulige gas field.In production process of the gas reservoir in horizontal well,when the gas output can not continuously carries the liquid out of the wellhead,loading liquid is generated in horizontal well bore which increases back pressure to the gas reservoir,limiting the gas well production capacity severely,and even causing the gas well water flooding,affecting the normal production of gas well.Based on the straight well continuous carrying liquid model,used angle related Lee Min continuous carrying liquid theory,the horizontal gas well critical carrying liquid production is determined,and combining with a single horizontal gas wells production dynamic,applicability and accuracy of this method in calculation to the horizontal gas well critical carrying liquid production in Sulige gas field is proved,which has important guiding significance of horizontal well's production.
