Coiled tubing push type perforation and bridge plug combined operation system and method

The invention relates to a coiled tubing push type perforation and bridge plug combined operation system. The problems that cost is high, time and labor are wasted and efficiency is low due to two-time perforation dragging construction of an existing oil and gas well are mainly solved. The device is characterized in that the continuous oil pipe is connected with a ball-throwing, hole-opening and detonating device and a plurality of stages of time-delay perforation units; the last stage of delay explosion propagation device is connected with a bridge plug ignition device and a bridge plug tool; the using method comprises the steps that the pipe string combining perforation and bridge plug setting is constructed, the topmost-stage ball-throwing hole-opening detonation device is detonated through well mouth pressurization, perforation of the topmost-stage reservoir stratum is completed through the topmost-stage perforating gun, then the detonation time of the next-stage perforating gun is delayed through the del
