When gas wells enter the late stage of production,the liquid carrying capacity is weak and the productivity is greatly re-duced.The development of plunger gas lift technology is of great significance to enhance oil recovery.In the background of increasing technological progress,intelligent plunger gas lift and intelligent robot drainage gas recovery technology have been applied in oil fields.The research status of production at home and abroad is investigated,three process principles are compared,the basic model and optimization of the process are studied,and the applicability and effect of the process are evaluated.And finally,the shortcomings of traditional plunger gas lift technology and the prospect of new intelligent system technology are pointed out.
