The invention belongs to the technical field of transforming an oil-gas field reservoir, aims to overcome the problem that the packer in the prior art easily fails due to a long-term repeated setting under a high-temperature high-pressure environment, and provides a multi-stage draggable water-jet packer tubular column and a technology. The multi-stage draggable water-jet packer tubular column comprises a water-jet gun and the packer, wherein the packer is connected to the lower end of the water-jet gun. The water-jet packer has a simple structure, a jet channel of the water-jet gun and a setting liquid inlet channel of the packer are simultaneously opened during the application of continuous operation of water-jet perforating and fracturing in a manner of throwing a ball to impact a sliding sleeve, the operation is convenient, the packer can be effectively protected, the service life of the packer can be effectively prolonged, and the working life of a nozzle of the water-jet gun can be prolonged to a maximum extent.
