Description
Technical Field
[0001] The utility model relates to the technical field of well logging monitors, in particular to a well logging monitor with an anti-collision structure. Background Art
[0002] Geophysical exploration is referred to as geophysical exploration. It refers to the detection of geological conditions such as lithology and geological structure by studying and observing changes in various geophysical fields. Well logging is an important method of geophysical exploration. It uses the electrochemical, conductive, acoustic, radioactive and other geophysical properties of rock formations to measure geophysical parameters, providing key data for the exploration and development of resources such as oil and natural gas. A well logging monitor is a well logging instrument that can survey and measure the geophysical parameters of rock formations in the well. Existing well logging monitors still have certain defects when used.
[0003] In the prior art, ultrasonic measurement is a common measurement method for well logging monitors. The acoustic characteristics of sound waves propagating in different media, such as speed, amplitude and frequency changes, are used to measure the geological profile, reservoir distribution, geological structure and other values of the well. The depth of the well can also be measured. During the use of the well logging monitor, an ultrasonic probe is placed in the well. Due to the presence of rock formations in the well and the vibration of the cable during the continuous descent of the ultrasonic probe, the probe tube and the ultrasonic probe are prone to collision with the rock formation, which can easily cause the electronic components inside the ultrasonic probe to loosen and be damaged, thereby affecting the well logging operation. Utility Model Content

[0006] Preferably, a plug-in structure is formed between the oblique block and the connecting block through a through hole, and the plug-in rod is made of stainless steel.
[0007] Preferably, the thread grooves are distributed at equal intervals on the slide rod.
[0008] Preferably, connecting plates are welded on both sides of the lead frame, a rotating shaft is welded between the two connecting plates, and a rotating block is rotatably connected to the outer side of the rotating shaft.
[0009] Preferably, an extension plate is welded to the bottom of the rotating block, and the inner thread of the extension plate is connected with a conical screw.
[0010] Preferably, the internal threads of the connecting plate are connected with bolts, and the surface of the wire rack is installed with a magnetic suction block.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the end of the plug-in rod is plugged into the interior of the connecting block, the inclined surface of the inclined block will be squeezed with the end of the connecting block, so that the inclined block will compress the stainless steel spring; when the inclined block is squeezed and slides into the interior of the plug-in rod, the end of the plug-in rod can slide to the deepest part of the connecting block; after the extension plate is fixed, the wire rack can be placed above the well; the extension plate can increase the placement length of the wire rack, so that the wire rack can be placed above the longer diameter of the well wall, thereby facilitating the ultrasonic probe to perform measurement operations.
[0012] 1. The well logging monitor uses the characteristics of sound waves propagating in underground media to obtain the physical parameters of underground rocks. During the use of the well logging monitor, the probe tube and the ultrasonic probe are prone to shaking in the well, and will collide with the rock formations on the well wall, causing the ultrasonic probe to be easily damaged. When the end of the plug-in rod is plugged into the interior of the connecting block, the inclined surface of the inclined block will be squeezed with the end of the connecting block, causing the inclined block to compress the stainless steel spring. When the inclined block is squeezed and slides into the interior of the plug-in rod, the end of the plug-in rod can slide to the deepest part of the connecting block. When the inclined block is reset, its end can pass through the through hole, thereby docking the plug-in rod with the connecting block, and sliding When the rod moves, the thread groove can be driven to move. When a designated group of thread grooves moves to the bottom position of the thread knob, the thread knob can be rotated. When the thread knob is rotated, the slide rod can be threadedly fixed through a designated group of thread grooves. The distance between the buffer pad and the probe can be adjusted accordingly according to the inner wall radius of the well. When the probe shakes, the protective block can prevent the probe and the ultrasonic probe from colliding with the inner wall of the well. At the same time, the buffer pad can reduce the force generated during the collision, so that the protective block and the buffer pad can protect the ultrasonic probe, thereby preventing the ultrasonic probe from being damaged by collision during the measurement process.
[0013] 2. The wire rack on the well logging monitor is used to guide the cable for laying out and reeling in, so that the ultrasonic probe can be placed accurately and safely in the well. The length of the traditional wire rack is usually fixed, which makes it difficult to place the wire rack above the well wall where the diameter is greater than its own length. When the extension plate moves, it can be separated from the magnetic block, and when the extension plate moves, it can drive the rotating block to move. When the extension plate rotates to the ground surface, the bolt can be rotated, and the bolt can limit the rotating block. When the extension plates on the wire rack can no longer rotate, the wire rack can be placed in the center position above the well so that the end of the extension plate is located on the soil surface. At this time, the conical screw can be rotated and inserted into the soil to fix the wire rack. After the extension plate is fixed, the wire rack can be placed above the well. The extension plate can increase the placement length of the wire rack, so that the wire rack can be placed above the well wall with a longer diameter, thereby facilitating the ultrasonic probe to perform measurement operations.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 and Figure 2 It can be seen that the utility model provides a technical solution: a well logging monitor with an anti-collision structure, comprising: a monitoring display body 1, a battery box 2, a wire rack 3, a wire rack 4, a probe 5 and an ultrasonic probe 6, the surface of the monitoring display body 1 is connected to the battery box 2 through a power line, the surface of the monitoring display body 1 is connected to the wire rack 3 through a cable, the outer side of the wire rack 3 is provided with a wire rack 4, the bottom of the wire rack 4 is connected to the probe 5 through a cable, the bottom end of the probe 5 is installed with an ultrasonic probe 6, a connecting block 7 is welded to the outer side of the probe 5, a through hole 8 is opened on the top of the connecting block 7, and the internal sliding plug of the connecting block 7 A plug-in rod 9 is connected, and a stainless steel spring 10 is connected to the inside of the plug-in rod 9 near the connecting block 7. One end of the stainless steel spring 10 is connected to an inclined block 11. The top of the plug-in rod 9 away from the inclined block 11 is threadedly connected to a threaded knob 12. The inside of the plug-in rod 9 is slidably connected to a slide rod 13. The inside of the slide rod 13 is provided with a threaded groove 14 matching the size of the threaded knob 12. A protective block 15 is welded to the end of the slide rod 13, and a buffer pad 16 is bonded to the outside of the protective block 15. A plug-in structure is formed between the inclined block 11 and the connecting block 7 through a through hole 8. The plug-in rod 9 is made of stainless steel, and the threaded grooves 14 are evenly spaced on the slide rod 13.
[0021] In specific implementation, the well logging monitor uses the characteristics of sound wave propagation in the underground medium to obtain the physical parameters of the underground rock. During the use of the well logging monitor, the probe 5 and the ultrasonic probe 6 are prone to shaking in the well, and will collide with the rock formation of the well wall, causing the ultrasonic probe 6 to be easily damaged. For this reason, the plug-in rod 9 can be pushed in the direction of the connecting block 7. When the end of the plug-in rod 9 is plugged into the interior of the connecting block 7, the inclined surface of the inclined block 11 will be squeezed with the end of the connecting block 7, so that the inclined block 11 will compress the stainless steel spring 10. When the inclined block 11 is squeezed and slid into the interior of the plug-in rod 9, the end of the plug-in rod 9 can slide to the deepest part of the connecting block 7. At this time, the inclined block 11 is no longer squeezed by the connecting block 7, so that the inclined block 11 can be reset by the stainless steel spring 10. When the inclined block 11 is reset, its end can pass through the through hole 8, so that the plug-in rod 9 is connected to the connecting block 7. At this time, the protective block 15 can be pushed according to the diameter of the well. When the protective block 15 moves, it can drive the buffer pad 16 and the slide bar 13 to move. When the slide bar 13 moves, it can drive the thread groove 14 to move. When a specified group of thread grooves 14 moves to the bottom position of the thread knob 12, the thread knob 12 can be rotated. When the thread knob 12 is rotated, the slide bar 13 can be threadedly fixed through a specified group of thread grooves 14. At this time, the distance between the probe tube 5 and the buffer pad 16 is slightly smaller than the radius of the well, so that the probe tube 5 can be smoothly placed in the well. The distance between the buffer pad 16 and the probe tube 5 can be adjusted accordingly according to the inner wall radius of the well.
[0022] See also Figure 1 and Figure 2 It can be seen that when the probe 5 shakes, the protective block 15 can prevent the probe 5 and the ultrasonic probe 6 from colliding with the inner wall of the well. At the same time, the buffer pad 16 can reduce the force generated during the collision, so that the protective block 15 and the buffer pad 16 can protect the ultrasonic probe 6, thereby preventing the ultrasonic probe 6 from being easily damaged by collision during the measurement process.
[0023] See also Figure 1 , Figure 3 and Figure 4 It can be seen that connecting plates 17 are welded on both sides of the wire rack 4, a rotating shaft 18 is welded between the two connecting plates 17, a rotating block 19 is rotatably connected to the outer side of the rotating shaft 18, an extension plate 20 is welded to the bottom of the rotating block 19, the internal thread of the extension plate 20 is connected to a conical screw 21, the internal thread of the connecting plate 17 is connected to a bolt 22, and a magnetic block 23 is installed on the surface of the wire rack 4, and a magnetic attraction structure is formed between the magnetic block 23 and the extension plate 20.
[0024] In specific implementation, the wire rack 4 on the well logging monitor is used to guide the cable to release and reel in the cable, so that the ultrasonic probe 6 can be accurately and safely placed in the well. The length of the traditional wire rack 4 is usually fixed, which makes it difficult for the wire rack 4 to be placed above the well wall whose diameter is greater than its own length. For this reason, the extension plate 20 can be pulled in a direction away from the wire rack 4. When the extension plate 20 moves, it can be separated from the magnetic block 23, and when the extension plate 20 moves, it can drive the rotating block 19 to move. When the rotating block 19 moves, it can rotate through the rotating shaft 18. When the extension plate 20 rotates to the ground surface, the bolt 22 can be rotated so that the end of the bolt 22 can be threaded and slid to the outside of the rotating block 19. At this time, the bolt 22 can limit the rotating block 19, so that the rotating block 19 and the extension plate 20 cannot continue to rotate. When the extension plates 20 on the wire rack 4 cannot continue to rotate, the wire rack 4 can be placed in the center position above the well so that the end of the extension plate 20 is located on the soil surface. At this time, the conical screw 21 can be rotated and inserted into the soil to fix the wire rack 4.
[0025] See also Figure 1 , Figure 3 and Figure 4 It can be seen that after the extension plate 20 is fixed, the wire rack 4 can be placed above the well. The extension plate 20 can increase the placement length of the wire rack 4, so that the wire rack 4 can be placed above the well wall with a longer diameter, thereby facilitating the ultrasonic probe 6 to perform measurement operations.
[0026] In summary, when using the well logging monitor with an anti-collision structure, the monitoring display body 1 and the battery box 2 are connected via a power cord, and then the two ends of the cable are respectively inserted into the pay-off rack 3 and the monitoring display body 1, and then the cable extended from the pay-off rack 3 is placed on the wire rack 4. The probe 5 and the ultrasonic probe 6 can be placed in the well through the wire rack 4. The sound wave signal emitted by the ultrasonic probe 6 passes through the wellbore and is reflected and refracted in the formation medium. When the reflected sound wave signal reaches the monitoring display body 1, the monitoring display body 1 will record the intensity and arrival time of the sound wave signal. According to the different propagation speeds of sound waves in different media, the well logging monitor can accurately measure the speed of the medium in the well, Parameters such as density and porosity. When the probe 5 shakes, the protective block 15 can prevent the probe 5 and the ultrasonic probe 6 from hitting the inner wall of the well. At the same time, the buffer pad 16 can reduce the force generated during the collision, so that the protective block 15 and the buffer pad 16 can protect the ultrasonic probe 6, so that the ultrasonic probe 6 is not easily damaged by collision during the measurement process. After the extension plate 20 is fixed, the wire rack 4 can be placed above the well. The extension plate 20 can increase the placement length of the wire rack 4, so that the wire rack 4 can be placed above the well wall with a longer diameter, thereby facilitating the ultrasonic probe 6 to perform measurement operations.
