摘　　要：卧龙河气田开采已进入后期,井筒积液对气井生产的影响越来越大,虽经过液体泡排剂的助排,但收效甚微。2006年底对卧83井等4口井实施固体泡排试验并取得了良好效果,为此,从固体泡排装置及工艺简介入手,对卧83井实施固体泡排的情况及效果进行了分析,认为固体泡排工艺在气井后期生产中具有推广应用的价值,并就固体泡排工艺如何运用于特殊气井提出了看法。For Wolonghe gasfield,the exploitation has been in a later stage and an effect of wellbore accumulation on production becomes larger and larger.The production effect is not so good with the help of liquid foaming agent.But good effect was obtained by a solid foaming experiment on 4 wells including well Wo-83 at the end of 2006.The paper analyzes the effect of solid foaming agent on well Wo-83 in terms of solid foam drainage installation and operation.And it also deems this solid foaming technique might be widely applied to later-stage gas well exploitation and presents some suggestions on how to use the technique to special gas wells.
