Preferably, the through hole 621 is an oval through hole for mounting the second screw. In this way, the through hole 621 is enabled to provide a certain buffer space for the second fixing piece 62. Thus, when the protection device 100 for a logging tool probe is subjected to axial impact in a downhole accident, the second clamping seat assembly 60 can move in the first direction or the second direction in the buffer space of the through hole 621 according to the direction of the impact force, so that the axial impact force on the logging tool probe 30 is reduced, and the protection effect on the logging tool probe 30 is further realized.

According to the present utility model, the second cartridge assembly 60 further includes a first clip 63 and a second clip 64 extending from the second body 61 in the second direction. The first and

second detents

63, 64 are each configured as partially cylindrical bodies and are radially spaced apart from one another. According to one embodiment of the utility model, grooves are provided in the second end of the tool probe 30 that are respectively adapted to the first and

second detents

63, 64 so that the first and

second detents

63, 64 can be more easily inserted into the tool probe 30 to form an effective engagement, further enhancing the securement of the tool probe 30.

In one embodiment of the present utility model, a plurality of screw holes are radially disposed on each of the first clamping member 63 and the second clamping member 64. The screw holes on the first clamping piece 63 and the screw holes on the second clamping piece 64 are symmetrically distributed along the radial direction. In this way, the first clamping member 63 and the second clamping member 64 can have a more stable connection relationship with the logging instrument probe 30, and the fixing of the logging instrument probe 30 is further improved.

In one embodiment of the utility model, a shock pad configured as a U-shape is disposed between the tool probe 30 and the first and

Specifically, the free ends of the first clamping member 63 and the second clamping member 64 are fixedly connected with the shock pad. A second end of the tool probe 30 is attached to the shock pad. Thus, when the protection device 100 for the logging tool probe is accidentally impacted in the axial direction in the downhole and the second clamping seat assembly 60 moves along the second direction, the second clamping seat assembly 60 will first strike the shock pad, so as to effectively attenuate the axial impact of the second clamping seat assembly 60, and further fix and protect the logging tool probe 30. In addition, the shock pad also has a centralizing effect on the probe extending out of the second end of the logging instrument probe 30, and further deformation of the probe due to axial impact force is avoided.

In one embodiment of the utility model, as shown in FIG. 1, a plurality of first seal rings 1 are provided on the outer circumference of a tool probe 30. The inner wall of the protection mechanism 10 is tightly attached to the first seal ring 1 in the axial direction. In this way, the tool probe 30 is able to maintain a stable position throughout the chamber 20, thereby reducing the impact on the survey results from the external environment. In addition, due to the existence of the sealing ring, the logging instrument probe 30 can also avoid direct contact with the well wall, and further the protection effect on the logging instrument probe 30 is realized.

Fig. 4 is a cross-sectional view at C-C in fig. 1. In one embodiment of the present utility model, as shown in fig. 1 and 4, a second sealing ring 2 is provided between the second fixing member 62 and the second support table 12. In this way, the second sealing ring 2 can play a certain flexible supporting role on the second fixing piece 62, so that the service life of the protection device 100 for the logging instrument probe is prolonged. In addition, when the protection device 100 for the logging tool probe is subjected to axial impact in a downhole accident, the second clamping seat assembly 60 moves to the first direction or the second direction to adjust, the sealing ring can increase the friction force between the second fixing piece 62 and the second supporting table 12, so that the axial impact force is effectively buffered, and the fixing and protecting effects on the logging tool probe 30 are further realized.

The utility model can solve the problems of fixing and protecting the logging instrument probe 30. On the one hand, the elliptical through hole 621 is formed in the second fixing member 62, so that the axial impact applied to the tool probe 30 is buffered. On the other hand, a through groove 511 is provided on the outer periphery of the first body 51, so that axial impact applied to the tool probe 30 is buffered by increasing friction between the first body 51 and the inner wall of the protection mechanism 10. In addition, the first sealing ring 1 and the second sealing ring 2 can also play a role in buffering axial impact applied to the logging instrument probe 30.
