Electric backwashing packer

The invention relates to an electric backwashing packer which comprises a barrel, a setting assembly, a backwashing assembly and a pressure testing assembly. A setting assembly, a backwashing assembly and a pressure testing assembly are arranged in the cylinder body at intervals; the setting assembly achieves setting through electric control. A backwashing channel is arranged in the cylinder body and is communicated with an annulus between the oil pipe and the casing pipe; the backwashing assembly electrically controls opening and closing of a backwashing channel; the pressure testing assembly is used for detecting formation pressure. Setting and opening and closing of a backwashing channel are achieved through electric control, so that setting and backwashing are more reliable, the pressure of the stratum where the packer is located is detected in real time in combination with the pressure testing assembly, data are provided for production operation, the working process can be checked in real time, and blind
