FIELD: oil production, particularly, automatic gathering, analysis and storage of well operation information. SUBSTANCE: device has measurement module 1 and recording unit 2. Measurement module 1 includes force cell 3, position pickup 4, pressure pickup 6 and temperature pickup 7. Outputs of said pickups are connected to respective measuring channels of recording unit 2. Channels of measurement of force, pressure, liquid level and temperature have amplifiers 8-10, multiplexer 11, digitizer 12, and time delay unit 13. Channel for measurement of motion has time delay unit 13, measurement triggering unit 14, frequency signal receiver 15 and sinusoidal oscillator 16. Said units are connected with respective ports and inputs of microprocessor controller 17 which has output to graphical indicator 22 and to electronic computer. Position pickup 4 is installed on ripe suspension unit, on retaining bracket. Pickups 5-6 are installed on wellhead equipment. Recording unit 2 is made for installation in rope suspension unit, or on wellhead equipment. EFFECT: extended functional potentialities. 4 dwg
