Abstract: According to the characteristics of gas lift wells at Wendong oilfield, production tubing acidization technology in gas life wells can remove formation blocks and dredge formation channels to increase production and efficiency without damaging down hole valves and without moving the production string. The indexes of the new unblocking agent,QJ-99, are better than those of conventional acid. The maximum pumping pressure equation is strongly practicable and can ensure the normal operation of each down hole gas lift valve after acidization stimulation. After applications, it has brought well economic efficiency and supplies Wendong oilfield a new stimulation technology.
