Block Su 75 of Sulige gas field belongs to low permeability, low pressure, and low abundance gas reservoir and the number of the wells producing water has been arising year by year, which means the problem which is called as liquid loading has become the main factor influencing the gas well deliverability. Plunger gas lift is one of the important drainage gas recovery technologies to extend the flowing production period of gas wells for it has high automation degree and is easy to manage. While during the field application, its low drainage gas recovery efficiency and bad stimulation effect occurs. So downhole pressure controlled plunger gas lift technology was developed and the field test in Su 75-26X well got better effect. Through practice, downhole pressure controlled plunger gas lift technology has high drainage gas recovery efficiency, for the technology is designed to use reservoirs energy fully, and the plunger is controlled automatically by pressure under the ground rather artificially on the surface. Obviously, downhole pressure controlled plunger gas lift technology has wide popularization and application foreground in Sulige gas field.
