With the continuous development of the gas field,the accumulation of liquid at the bottom of the well gradually increases,and its impact on the spontaneous flow capacity and gas production capacity of the gas well is gradually intensified,which seriously affects the economic benefits and mining life of the gas well,and may even drown the gas well,leading to production suspension or abandonment.Foam drainage gas recovery technology has become the main measure of gas field drainage gas recovery because of its convenient construction,cheap and efficient characteristics.In order to ensure the continuous and stable production of gas fields,it is very important to study the technological innovation management of bubble discharge process.Therefore,this paper first introduces the concept,necessity and key points of technological innovation management,and then proposes from the perspective of technological innovation management that the technological innovation of bubble drainage process can be carried out from four aspects:optimization of bubble drainage agent,optimization of foam eliminator,research and development of intelligent equipment and pipeline improvement.Then,the technological innovation of drainage production in Yan145-Yan518 well area is taken as an example to illustrate.
