When using the logging information to study the source rock, cap rock and the combination of source, reservoir and cap of oil and gas, it is necessary to straighten the geophysical logging tool to prevent affecting the detection results.

[0003] For example, a straightening device for a geological geophysical logging tool with the authorization announcement number of "CN221169499U" can be fixed again through a splint after the probe tube reaches the specified depth, without repeatedly adjusting the angle of the probe tube, which is simple and convenient to operate and saves time.

[0025] Working principle:

[0026] When straightening the geophysical prospecting well instrument:

[0027] Preparation process:

[0028] Place this device at the position to be detected, place the two bottom plates 7 on the ground, and at the same time pass the geophysical prospecting well instrument through the frame body 1 and the sleeve 10.

[0029] Clamping process:

[0030] The operator rotates the handle 5 so that the handle 5 can drive the stud 13 to rotate, and the stud 13 can drive the threaded plates 3 on both sides to move relative to each other, and the threaded plates 3 on both sides can drive the first frames 4 on both sides to move synchronously, so that the first frame 4 can drive the inner square rod 204 to move synchronously, and the square rods 204 on both sides and the first frames 4 on both sides can drive the rollers 203 on both sides to rotate, so that the rollers 203 on both sides can press against the outer wall of the geophysical well logging instrument to clamp the geophysical well logging instrument (the outer wall of the roller 203 is cylindrical, so that the clamping contact area is smaller, and it can be tilted when pushing the geophysical well logging instrument).

[0031] The process of righting:

[0032] When the geophysical well logging instrument is offset and needs to be straightened, the operator pulls the frame 1, so that the frame 1 drives the sleeve 10 to rotate around the rotating rods 905 on both sides. While rotating, the frame 1 can drive the two rollers at the lower end to clamp the geophysical well logging instrument. The rollers 203 on both sides of the lower end can drive the geophysical well logging instrument to rotate at the same angle, so that the geophysical well logging instrument can be straightened in the front and rear directions. While the rotating rod 905 rotates, the straight plate 901 can be driven to rotate, so that the straight plate 901 can drive the first bolt 902 to rotate synchronously. At the same time, the first bolt 902 is rotated, so that the first bolt 902 can drive the top block 903 to move toward the disk 904, so that the top block 903 can be concave with the surface of the disk 904. The triangular protrusion in the groove is pressed tightly to fix the angle of the straight plate 901. The angle of the straight plate 901 is fixed, so that the angle of the frame 1 is fixed. At the same time, the operator pushes the second frame 201 so that the second frame 201 can drive the two square rods 204 provided on the inner wall to rotate, so that the square rods 204 on both sides and the second frame 201 can synchronously move the rollers 203 on both sides of the upper end, so that the roller 203 on one side can push the geophysical well logging instrument to rotate in a direction perpendicular to the vertical plates 8 on both sides, so that the geophysical well logging instrument can be straightened in the left and right directions. After the adjustment is completed, the second bolts 205 on both sides are rotated so that one end of the second bolts 205 on both sides can be pressed against the outer wall of the second frame 201, so that the position of the second frame 201 can be fixed.
