As shown in fig. 8, the sidewall contact device provided by the present utility model is vertically placed in the measuring well 33, and then the sidewall contact device is lowered to 3300 m.
The driving motor 9 is started, and the driving motor 9 drives the transmission screw 10 to rotate, and finally drives the pushing device center pull rod 7 and the top disc 8 to move downwards and away from the abutting part 41 of the rotating head 4 through the transmission screw 10.

As shown in fig. 9, the pusher is gradually pulled up to 3200 m.

The well diameter head 22 at the end part of each well diameter leg 3 is always clung to the well wall in the whole measuring process (so as to achieve the purpose of real well condition). Therefore, in the process of pulling up, as the inclination angle of the caliper leg 3 is continuously changed, the rotation angle of the abutment portion 41 is also continuously changed, and thus the position of the sensor push rod 5 is also continuously changed, and finally, the displacement data measured by the displacement sensor 2 is continuously changed.
After the pulling is finished, the driving motor 9 is started, the driving motor 9 drives the transmission screw 10 to reversely rotate compared with the prior art, and the center pull rod 7 of the sidewall contact device and the top disc 8 are finally driven to upwards move through the transmission screw 10 and push the abutting part 41 of the rotating head 4 upwards.

In the process of pulling up 100 meters, the caliper head 22 of each caliper leg 3 is always attached to the well wall, so that the displacement sensor 2 corresponding to each caliper leg 3 can generate different real-time data, each data is regarded as a curve 28, as shown in fig. 10, and 6 curves 28 are obtained. The true shape of the well is simulated by 6 curves 28.
