[0042] The present invention also provides a method for using a reusable geophysical multi-parameter measuring device, comprising the following steps:

[0043] Step 1: lowering a reusable geophysical multi-parameter measuring device to a target monitoring depth in a deep well using a winch;

Each parameter is first transmitted via high-temperature and high-pressure wires and stored in the data acquisition system 2.

[0046] Step 4: When the measuring device needs to be repaired or the target monitoring depth needs to be changed, the first contact arm 5 is driven by the first support arm 4 to move and retract along the radial direction of the measuring device using the first support and fixing system. The second contact arm 19 is driven by the second support arm 18 to move and retract along the radial direction of the measuring device using the second support and fixing system, thereby separating the measuring device from the deep well inner wall 14.
