Abstract: An integrated plugging and perforating operation system is provided, including an operation truck, a wellhead equipment pry, and a centralized control room. A mechanical mechanism and a power mechanism are arranged on a chassis of the operation truck. The mechanical mechanism includes a turntable assembly, where a telescopic arm assembly is installed on the turntable assembly, a mechanical arm assembly for logging operation is installed at an operating end of the telescopic arm assembly, and a logging winch assembly and a follow-up winch assembly are arranged at a counterweight end of the telescopic arm assembly to form a counter weight of the telescopic arm assembly. The power mechanism is configured for providing power output to the mechanical mechanism.

Abstract: A wellhead automatic positioning method and a system of a plugging and perforating operation machine are provided. The method includes: determining a wellhead position, and acquiring standard positioning parameters of a boom according to the wellhead position and a tool string length, where the positioning parameters include a standard extension length L of the boom, a standard lifting length J, and an included angle ? between a projection of the boom and a wellhead; acquiring actual positioning parameters of the boom, where the actual positioning parameters include an actual length L? of the boom, an actual lifting length J?, and an initial angle ?? between the projection of the boom and the wellhead; and according to the standard positioning parameters and the actual positioning parameters of the boom, making the boom to extend and retract, lift and lower, and rotate to complete automatic positioning of the wellhead.
