Due to the separate production of gas and oil，the production cycle is too long and the recovery ratio is low in Bozhong29-4 Oilfield，and the electric load cannot meet the needs of multi-well production at the same time since it reached its upper limit. Aiming at these problems，gas and ESP combination lift was proposed using the self-produced gas in the production wells to achieve the goal of oil and gas production at the same time. Production system composed of reservoir，wellbore and ESP-gas lift system was taken as the study object. The method of node analysis and dual system coupling design was used. Regarding the efficient coordination of production of gas lift and ESP as the goal，the method and steps of working parameters design under different conditions were given based on the power of the ESP. The optimized production project was determined eventually. The calculation results of a certain well show that the combination lift can effectively reduce the pump series and pump power to 40.2% and 40.6% of the original compared with single ESP lift system under the condition of same flow rate. The problem of large load of single lift system was solved，so that multiple wells can product at the same time and the production of platform may be increased.
