Well body condition imaging logging instrument and logging method

The invention discloses a well body condition imaging logging instrument and logging method. The well body condition imaging logging instrument comprises an instrument main body, wherein a sensor assembly is arranged on the instrument main body, and one end of the sensor assembly is connected with a rotating driving pup joint; and the rotating driving pup joint is used for driving the sensor assembly to rotate to send and receive well wall signals in a rotating manner, and then well body condition information is obtained. The instrument body comprises an instrument circuit tube, and he instrument circuit tube is connected with the output end of the sensor assembly and used for controlling the sensor assembly to emit an angle interval and/or the pulse width of a sound wave pulse to the wellwall, and controlling startup, shutdown and/or the rotating speed and/or the cycle start and/or angular sampling pulses of the rotating driving pup joint, wherein the well body condition informationis an echo, reflected by t
