Electric submersible pump jamming real-time early warning method based on production data and high-frequency data

The invention discloses an electric submersible pump jamming real-time early warning method based on production data and high-frequency data. The production data and the high-frequency data of an oil well are collected, a change curve of each parameter is drawn, the change characteristics and rules of the parameters are compared with a theoretical change pattern diagram in a pump jamming process, and therefore the quick and accurate early warning of the jamming risk of an electric submersible pump is achieved. The pump jamming reason is found in combination with geological oil reservoirs and actual well conditions, timely guiding is conducted, effective measures are taken on site, the electric submersible pump jamming risk is relieved, and efficient operation of the oil well is maintained. When electric submersible pump jamming risk early warning is conducted, the response relation between the motor vibration amplitude and the pump jamming risk degree is utilized, four grades are obtained through division acc
