Sulige gas field lies in the desertification area of Ordos Basin, and the natural environment is adverse there. The difficulty of using traditional methods to manage thousands of gas wells there is great. A kind of emergent shut off valve is developed and introduced in this paper, and the problems of gas well management are solved. Firstly, the development background of emergent shut off valve at gas wellhead is introduced, and the gas collection pattern of medium and low pressure in Sulige gas field is involved. Then, the design requirements of the valve are described. Subsequently, the structure, working principle, and design parameters of the valve are illustrated. Finally, field application of the valve is introduced. By the end of 2016, thousands of the valves developed in this paper have been applied in Sulige gas field. Good adaptability and performance have been shown in application. It could be remote controlled and the protection functions of overpressure and under pressure are reliable. The difficulties of gas well production and management could be solved by application of emergent shut-off valve at gas wellhead. The level of the gas well management could be improved with remarkable benefits.
