摘　　要：把球塞气举排水采气系统划分为压缩机组、地面注气管线、井内注气油管和球塞举升油管等几个子系统,分别建立了评价各个子系统效率的数学模型,从而得到了球塞气举排水采气系统效率的计算方法,并进行了实例计算与分析,所获得的结论及认识对进一步探讨球塞气举举升机理具有重要意义。The dewatering gas production system by pig gas-lift is divided into several subsystems, including compressor set, surface gas injection pipeline, wellbore gas injection tubing, pig lift tubing and so on. Mathematical model has been built respectively to evaluate the efficiency of each subsystem, so as to obtain the method for calculating efficiency of dewatering gas production system by pig gas-lift, and the case calculation and analysis have been performed. The conclusion and recognition acquired have an important sense in further research on the mechanism of pig gaslift.
