The utility model discloses an ASP flooding double-layered tube packer which is designed for meeting the requirement for a large flushing channel and the requirement of an ASP flooding solution double-layered tube for carrying out multi-layered and multi-section separate injection. A seal-section inner tube of the packer is inserted into the top end of a central tube. A middle connector which is arranged on the central tube in a sleeved mode is connected with an upper connector and a flush valve sleeve. A liner tube is connected with the central tube. A rubber tube and a pin mounting sleeve are arranged on the liner tube in a sleeved mode. A locking ring and a locking ring locating ring arranged on the liner tube in a sleeved mode are arranged in a setting piston bush connected with the pin mounting sleeve. A setting piston and a lower connector are arranged on the liner tube in a sleeved mode. The lower connector is connected with the central tube and the like. On the premise that multi-layered and multi-section different medium and pressure injection of oil layers in an ASP flooding separate injection well is achieved by utilizing the ASP flooding double-layered tube packer, layering flow measurement in the well is omitted, and consequently the measurement and deployment efficiency is improved. Due to the fact that a separate injection tube column formed by the packer can meet requirements of reverse well-flushing, thin layers are divided into a high group and a lower group according to the permeability ratio, the number of the layers in each group is unconstrained, stratum separation is achieved, and the requirements of downhole measurement can be met.
