The utility model relates to an oil well supply and drainage coordination device, which is a liquid supply and discharge coordination device used for oil production in an oil field. The utility model is characterized in that the central controller comprises a microprocessor, a clock unit, a storage unit, a keyboard, a display unit, a communication interface and a control output unit. A clock unit, a storage unit, a keyboard, a display unit, a communication interface and a control output unit are provided with wires connected to the microprocessor. The echo detection unit is provided with a wire connecting microprocessor, wherein the echo detection unit is provided with a wire connecting sound control unit, and the sound control unit and the echo detection unit are fixed at the oil well head. The isolation contact of the control output unit is output to the speed regulator of the motor. The utility model has the advantages that the annular liquid level of the oil well can be detected at any time, so that the mining speed of the oil well is always in a reasonable state. An oil well suitable for pumping by rod pump or rod less pump will not produce evacuation, insufficient liquid supply and liquid level impingement.
