This paper analyzes the typical construction curve of mixed gas fracturing and summarizes the law of gas injection pressure variation during the construction of liquid nitrogen pump truck. A gas phase design method based on equipment capability is recommended for gas injection design. The field application shows that this A method has a strong practicality and maneuverability; at the same time, introduces some experiences of operating liquid nitrogen pump truck in the process of mixed gas fracturing
