摘　　要：近年来,固体泡排棒在靖边气田弱喷产水气井得到了广泛应用,取得了一定效果,但是对于一些压力低、能量弱、积液严重、无产量、频临枯竭的气井不能达到预期效果,甚至可能造成气井堵塞。针对上述问题,筛选出一种不需要气流搅动便可自行起泡、泡排能力强的新型泡排棒(UT-6B),并与传统泡排棒泡排效果进行对比,论证了自发泡型泡排棒的携液能力与应用前景,为靖边气田的泡沫排水采气工艺增加了新的选择。In recent years,solid foam drainage stick has been widely applied to weak-blowout water-producing gas wells in Jingbian gasfield and obtains a certain success.Certainly,there are some defects,including,the solid one not achieving an expected result for gas wells featured by low pressure,small capacity and serious liquid loading,as well as yield-free and dying gas wells;and even occurring blockage.So,in this paper,a new self-foaming drainage stick （UT-6B） is selected,and its drainage effect is compared with that of conventional ones.Moreover,the liquid-carrying capacity of the stick and its application prospect are also demonstrated.The new stick may provide another option for foam drainage gas recovery in Jingbian gasfield.
