Gas production with water draining by hydraulic pump alone

After ten years of production in Sebei gas field in Qinghai, some wells are shut off or gas production decreases because of formation pressure decreasing and production of edge and bottom water and interlayer water production increasing year by year. Sebei gas field is belonged to Quaternary sand gas field, so it is general that formation produces sand. Pump withdraw and electricity submersible pump etc., are not suit to the site becase of no electricity onsite, according to technology adaption analysis of gas production with water draining. In view of the high water production wells, a new technology that can not only withdraw water quickly and recover gas production but also suit the site construction conditions is needed to solve the problems.
