Autonomous measurement and control device for pumping instrument recoverable drill rod protective sleeve out of well logging

According to the autonomous measurement and control device for pumping the recyclable drill pipe protective sleeve out of the logging well of the instrument, the autonomous measurement and control device is arranged at the top end of an instrument string, and the instrument string is fixed in a recyclable drill pipe protective sleeve combination; the autonomous measurement and control device judges the position of the instrument string according to the induction of the permanent magnet on the recoverable drilling tool protective sleeve combination, and judges and controls the pumping-out state of the instrument string; the problems of accurate power-on control and automatic release and recovery of a mechanical pushing device of an instrument string in drilling rod protective sleeve pump-out logging construction are solved. When the magnetic sensor module passes through the magnetic field area of the permanent magnet, the position of the protective sleeve can be sensed, position judgment is accurately made, an
