[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is for reference. Figures 1-10 A drilling directional probe 1000 according to an embodiment of the present invention is described, the drilling directional probe 1000 comprising:

[0047] 100mm pressure-resistant pipe;

[0048] The power control section 400 and the sensor processing section 500 are both located inside the pressure-resistant tube 100 and arranged along the axial direction of the pressure-resistant tube 100. The power control section 400 and the sensor processing section 500 are connected.

[0049] The first connection assembly 200 is fixed to one end of the pressure-resistant tube 100 and connected to the power control short section 400, and the first connection assembly 200 is also adapted to communicate with the first external device.

[0050] The second connection assembly 300 is fixed to the other end of the pressure-resistant tube 100 and connected to the sensor processing section 500, and the second connection assembly 300 is also adapted to communicate with a second external device.

[0051] The first damping element 600 is located inside the pressure-resistant tube 100. The first damping element 600 is sleeved on the outside of the power control section 400 and / or the outside of the sensor processing section 500. It can also be understood that the first damping element 600 is sleeved on the outside of the power control section 400 or the outside of the sensor processing section 500, or the first damping element 600 is sleeved on the outside of both the power control section 400 and the sensor processing section 500. The first damping element 600 abuts against the pressure-resistant tube 100.

[0052] The pressure-resistant tube 100 can be made of a high-strength, corrosion-resistant metal material, such as beryllium copper. However, this invention is not limited to this; the pressure-resistant tube can also be made of other materials, as long as it is made of a high-strength, corrosion-resistant material capable of withstanding pressure. By using beryllium copper as the material for the pressure-resistant tube 100, its high-temperature resistance and corrosion resistance can be improved. The power control sub-section 400 can be made of a high-strength, non-magnetic metal material, such as aerospace aluminum. However, this invention is not limited to this; the power control sub-section 400 can also be made of other materials, as long as it is made of a high-strength, non-magnetic material. The power control sub-section 400 may include a rectifier circuit board and a signal control main control board, but this invention is not limited to this; the power control sub-section 400 may also include other components, as long as they can form the power control sub-section 400 and allow it to function normally.

[0053] Both the power control section 400 and the sensor processing section 500 can be housed within the pressure-resistant tube 100, and are arranged axially along the pressure-resistant tube 100. The power control section 400 and the sensor processing section 500 are connected. It should be noted that the power control section 400 and the sensor processing section 500 are communicatively connected, and can also be fixedly connected. For example, they can be fixedly connected by bolts, snap-fit, or adhesive. However, the invention is not limited to these methods; other connection methods are also possible, as long as the power control section 400 and the sensor processing section 500 are fixedly connected.

[0054] The first connecting assembly 200 can be fixedly mounted on one end of the pressure-resistant tube 100, and the first connecting assembly 200 is connected to the power control sub-section 400. The first connecting assembly 200 is communicatively connected to the power control sub-section 400, and the first connecting assembly 200 can also be communicatively connected to a first external device. The first connecting assembly 200 and the power control sub-section 400 can be fixedly connected, for example, the connection between the first connecting assembly 200 and the power control sub-section 400 can be a threaded connection. However, the present invention is not limited to this, and the connection between the first connecting assembly 200 and the power control sub-section 400 can also be in other ways, as long as the first connecting assembly 200 and the power control sub-section 400 are fixedly connected.

[0055] The second connecting assembly 300 can be fixed to the other end of the pressure-resistant tube 100, and the second connecting assembly 300 is connected to the sensor processing section 500. The second connecting assembly 300 is communicatively connected to the sensor processing section 500, and the second connecting assembly 300 is also suitable for communicatively connecting to a second external device. The second connecting assembly 300 and the sensor processing section 500 can be fixedly connected, for example, the second connecting assembly 300 and the sensor processing section 500 can be fixedly connected by bolts, or the second connecting assembly 300 and the sensor processing section 500 can be snap-fitted, or the second connecting assembly 300 and the sensor processing section 500 can be glued. However, the present invention is not limited to these. The second connecting assembly 300 and the sensor processing section 500 can also be connected by other methods, as long as the second connecting assembly 300 and the sensor processing section 500 are fixedly connected.

[0056] The first damping element 600 can be located inside the pressure-resistant tube 100. The first damping element 600 is sleeved on the outside of the power control section 400 and / or the sensor processing section 500. This application uses the example of the first damping element 600 being sleeved on the outside of both the power control section 400 and the sensor processing section 500 for illustration. The first damping element 600 abuts against the pressure-resistant tube 100. For example, the first damping element 600 can be sleeved on both ends and the middle portion of the outside of the power control section 400, and on one end and the middle portion of the outside of the sensor processing section 500. However, the invention is not limited to this; as long as the first damping element 600 is sleeved on the outside of both the power control section 400 and the sensor processing section 500, and the first damping element 600 abuts against the inner wall of the pressure-resistant tube 100, it is acceptable.

[0057] By axially arranging a power control sub-section 400 and a sensor processing sub-section 500 within the pressure-resistant tube 100, and connecting the power control sub-section 400 and the sensor processing sub-section 500, a first connection assembly 200 is provided at one end of the pressure-resistant tube 100 and connected to the power control sub-section 400, and a second connection assembly 300 is provided at the other end of the pressure-resistant tube 100 and connected to the sensor processing sub-section 500, a communication connection between the first connection assembly 200 and the second connection assembly 300 can be achieved. The first connection assembly 200 is also suitable for communication connection with a first external device (e.g., a pulser), and the second connection assembly 300 is also suitable for communication connection with a second external device, enabling the drilling directional probe 1000 to communicate with external equipment. Inside the pressure-resistant tube 100, a first vibration damping element 600 is sleeved on the outside of the power control section 400 and / or the sensor processing section 500. The first vibration damping element 600 can be a ring structure, made of rubber material, and abuts against the inner wall of the pressure-resistant tube 100. The first vibration damping element 600, sleeved on the outside of the power control section 400, can radially limit the power control section 400 and absorb energy, thus providing a buffering and vibration-damping effect for the power control section 400. To reduce the radial vibration amplitude of the power control section 400, the first vibration damping element 600, which is sleeved on the outside of the sensor processing section 500, can radially limit the sensor processing section 500 and absorb energy, thus buffering and damping the sensor processing section 500. This reduces the radial vibration amplitude of the sensor processing section 500, thereby giving the drilling directional probe 1000 a vibration damping effect and buffering and damping the drilling directional probe 1000, thereby improving the stability of the drilling directional probe 1000.

[0058] Therefore, a first damping element 600 is sleeved on the outside of the power control section 400 and / or the outside of the sensor processing section 500. The first damping element 600 can be a ring structure, made of rubber material, and abuts against the inner wall of the pressure-resistant tube 100. The first damping element 600 sleeved on the outside of the power control section 400 can radially limit the power control section 400 and absorb energy, thus buffering and damping the power control section 400 and reducing vibration. The power control section 400 controls the radial vibration amplitude. The first damping element 600, which is sleeved outside the sensor processing section 500, can radially limit the sensor processing section 500 and absorb energy, thus buffering and damping the sensor processing section 500. This reduces the radial vibration amplitude of the sensor processing section 500, thereby giving the drilling directional probe 1000 a vibration reduction effect and buffering and damping the drilling directional probe 1000, thereby improving the stability of the drilling directional probe 1000.

[0059] According to some embodiments of the present invention, such as Figure 2 As shown, the first connection assembly 200 may include: a first connection sleeve 21 and a first connection end 22. The first connection sleeve 21 is fixedly connected to one end of the pressure-resistant tube 100. The first connection end 22 is fixed at the end of the first connection sleeve 21 away from the pressure-resistant tube 100. The first connection end 22 is connected to the power control sub-section 400 and is adapted to communicate with a first external device.

[0060] The first connecting sleeve 21 can be made of a high-strength, corrosion-resistant metal material, such as beryllium copper, which can improve its high-temperature resistance and corrosion resistance. However, the invention is not limited to this; as long as the first connecting sleeve 21 is made of a high-strength, corrosion-resistant material, it is acceptable. The first connecting sleeve 21 is fixedly connected to one end of the pressure-resistant tube 100. For example, the first connecting sleeve 21 and the pressure-resistant tube 100 can be fixedly connected by threads. For example, the outer peripheral wall of the first connecting sleeve 21 has external threads, and the inner peripheral wall of the pressure-resistant tube 100 has internal threads. The external threads of the first connecting sleeve 21 and the internal threads of the pressure-resistant tube 100 are engaged to fix the first connecting sleeve 21 to the pressure-resistant tube 100. However, the invention is not limited to this; the first connecting sleeve 21 and the pressure-resistant tube 100 can also be connected in other ways, as long as the first connecting sleeve 21 and the pressure-resistant tube 100 are fixedly connected.

[0061] A sealing element 27 may be fitted on the outside of the first connecting sleeve 21. For example, the sealing element 27 may be an annular structure. The sealing element 27 is located between the first connecting sleeve 21 and the pressure-resistant tube 100, and at the connection between the first connecting sleeve 21 and the pressure-resistant tube 100. The sealing element 27 can seal the gap between the first connecting sleeve 21 and the pressure-resistant tube 100. However, the present invention is not limited to this. The sealing element 27 may also be of other types, as long as the sealing element 27 can play a sealing role.

[0062] The first connection end 22 can be a core connector. The first connection end 22 can be fixed at the end of the first connection sleeve 21 away from the pressure tube 100. The first connection end 22 is communicatively connected to the power control sub-section 400, and the first connection end 22 is suitable for communicatively connected to the first external device.

[0063] Therefore, by providing a first connecting sleeve 21 in the first connecting assembly 200, and fixing the first connecting sleeve 21 to one end of the pressure-resistant tube 100, the first connecting assembly 200 and the pressure-resistant tube 100 can be fixedly assembled. The first connecting end 22 is fixed at the end of the first connecting sleeve 21 away from the pressure-resistant tube 100. The first connecting end 22 is communicatively connected to the power control sub-section 400 and to the first external device, thus enabling the communication connection between the power control sub-section 400 and the first external device.

[0064] According to some embodiments of the present invention, such as Figure 2 As shown, the first connection assembly 200 may further include: a first fixed shaft 23, an elastic element 24, and a first connecting shaft 25. The first fixed shaft 23 is disposed in the first connecting sleeve 21 and has a mounting groove 26 formed at its end near the pressure-resistant tube 100. One end of the elastic element 24 and the first connecting shaft 25 are installed in the mounting groove 26. The elastic element 24 is disposed between the bottom wall of the mounting groove 26 and the first connecting shaft 25. The other end of the first connecting shaft 25 is fixedly connected to the power control sub-section 400.

[0065] The first fixed shaft 23 can be disposed within the first connecting sleeve 21, and an installation groove 26 can be formed at the end of the first fixed shaft 23 near the pressure-resistant tube 100. The elastic element 24 can be a disc spring assembly or a spring sheet, but the present invention is not limited to these. The elastic element 24 can also be of other types, as long as the elastic element 24 can play an elastic damping role. One end of the elastic element 24 and the first connecting shaft 25 is installed in the installation groove 26. The elastic element 24 is disposed between the bottom wall of the installation groove 26 and the first connecting shaft 25. The other end of the first connecting shaft 25 is fixedly connected to the power control short section 400. For example, the first connecting shaft 25 and the power control short section 400 can be threaded, but the present invention is not limited to this. The first connecting shaft 25 and the power control short section 400 can also be connected in other ways, as long as the first connecting shaft 25 and the power control short section 400 are fixedly connected.

[0066] Therefore, by setting the elastic element 24 between the bottom wall of the mounting groove 26 and the first connecting shaft 25, along the axial direction of the drilling directional probe 1000, the elastic element 24 plays a vibration damping and buffering role, which can play a vibration damping role in the internal short section of the anti-pressure pipe 100, thereby achieving the effect of improving the vibration damping of the drilling directional probe 1000. The first connecting shaft 25 is fixedly connected to the power control short section 400, which can realize the fixed connection between the first connecting assembly 200 and the power control short section 400.

[0067] According to some embodiments of the present invention, such as Figure 4 As shown, the power control section 400 may include: a first mounting frame 41 and a first circuit board 42. The first circuit board 42 is fixed to the first mounting frame 41. The first circuit board 42 is connected to the first connection end 22 of the first connection assembly 200 and is also connected to the sensor processing section 500. The first damping member 600 is sleeved on the outside of the first mounting frame 41.

[0068] The first mounting frame 41 can be made of a high-strength, non-magnetic metal material, such as aerospace-grade aluminum. However, the invention is not limited to this; the first mounting frame 41 can also be made of other materials, as long as it is made of a high-strength, non-magnetic material. The first circuit board 42 can be fixed to the first mounting frame 41. The first circuit board 42 is communicatively connected to the first connection terminal 22 of the first connection assembly 200 and also communicatively connected to the sensor processing sub-section 500. For example, the first circuit board 42 and the first connection terminal 22 can be connected by a wire harness, and the first circuit board 42 and the sensor processing sub-section 500 can also be connected by a wire harness. The first circuit board 42 may include the rectifier circuit board and the signal control main control board in the above embodiments.

[0069] The first damping member 600 can be sleeved on the outside of the first mounting frame 41. For example, the first damping member 600 can be sleeved on both ends and the middle position of the outside of the first mounting frame 41. However, the present invention is not limited to this. The first damping member 600 can also be sleeved on other parts of the outside of the first mounting frame 41, as long as the first damping member 600 can be sleeved on the outside of the first mounting frame 41.

[0070] Thus, the first circuit board 42 is fixed to the first mounting frame 41. The first circuit board 42 is connected to the first connection end 22 of the first connection assembly 200 and also to the sensor processing section 500, enabling communication and electrical connections between the power control section 400 and the sensor processing section 500, thereby achieving communication connections between the first connection assembly 200 and the second connection assembly 300. By sleeved on the outside of the first mounting frame 41, the first vibration damper 600 can buffer and dampen the power control section 400.

[0071] According to some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the first mounting frame 41 may have a first connecting segment 43 at the end near the sensor processing section 500, and the sensor processing section 500 may include a second mounting frame 51. The end of the second mounting frame 51 near the power control section 400 may have a second connecting segment 52, and the first connecting segment 43 and the second connecting segment 52 are fixedly connected.

[0072] The first mounting frame 41 may have a first connecting section 43 at the end near the sensor processing section 500. The sensor processing section 500 may include a second mounting frame 51, which may be made of a high-strength non-magnetic metal material, such as aerospace aluminum. However, the present invention is not limited to this, and the second mounting frame 51 may also be made of other materials, as long as the second mounting frame 51 is made of a high-strength non-magnetic material.

[0073] The end of the second mounting frame 51 near the power control section 400 may have a second connecting section 52, and the first connecting section 43 and the second connecting section 52 are fixedly connected. For example, the first connecting section 43 and the second connecting section 52 may be fixedly connected by bolts, or the first connecting section 43 and the second connecting section 52 may be snap-fitted, or the first connecting section 43 and the second connecting section 52 may be glued. However, the present invention is not limited to these. The first connecting section 43 and the second connecting section 52 may also be connected in other ways, as long as the first connecting section 43 and the second connecting section 52 are fixedly connected.

[0074] Therefore, by providing a first connecting section 43 at the end of the first mounting frame 41 near the sensor processing section 500 and a second connecting section 52 at the end of the second mounting frame 51 near the power control section 400, and fixing the first connecting section 43 and the second connecting section 52 together, the power control section 400 and the sensor processing section 500 can be fixedly connected, and the first connecting section 43 and the second connecting section 52 can be easily assembled together, reducing the assembly difficulty of the drilling directional probe 1000.

[0075] According to some embodiments of the present invention, such as Figure 5 and Figure 7 As shown, the first connecting segment 43 may have a first plug-in end 44, and the second connecting segment 52 may have a second plug-in end 53. The first plug-in end 44 and the second plug-in end 53 are plugged in to enable the power control section 400 and the sensor processing section 500 to communicate with each other.

[0076] The first connecting segment 43 may have a first plug-in end 44, and the second connecting segment 52 may have a second plug-in end 53. For example, the first plug-in end 44 may be one of a male core connector and a female core connector, and the second plug-in end 53 may be the other of a female core connector and a male core connector. However, the present invention is not limited to this. The first plug-in end 44 and the second plug-in end 53 may also be other components, as long as the first plug-in end 44 and the second plug-in end 53 can be plugged in and cooperate.

[0077] Therefore, by plugging the first plug-in end 44 and the second plug-in end 53 together, it is easy to assemble the first plug-in end 44 and the second plug-in end 53 together, enabling the power control section 400 and the sensor processing section 500 to communicate, thereby realizing the communication connection between the first connection assembly 200 and the second connection assembly 300.

[0078] According to some embodiments of the present invention, such as Figure 5 and Figure 7As shown, the first connecting segment 43 may have a first positioning part 45, and the second connecting segment 52 may have a second positioning part 54. The first positioning part 45 and the second positioning part 54 are positioned and cooperated to fix the relative positions of the first mounting frame 41 and the second mounting frame 51.

[0079] The first connecting segment 43 may have a first positioning part 45, and the second connecting segment 52 may have a second positioning part 54. Both the first positioning part 45 and the second positioning part 54 may include a positioning pin and a positioning hole. The positioning pin is adapted to be inserted into the corresponding positioning hole. However, the present invention is not limited to this. The first positioning part 45 and the second positioning part 54 may also be other types of positioning components, as long as both the first positioning part 45 and the second positioning part 54 can play a positioning role. After the first positioning part 45 and the second positioning part 54 are assembled together, the relative positions of the first mounting frame 41 and the second mounting frame 51 can be fixed.

[0080] Therefore, through the positioning cooperation of the first positioning part 45 and the second positioning part 54, the relative positions of the first mounting frame 41 and the second mounting frame 51 can be fixed, thereby making the structure of the drilling directional probe 1000 stable and reliable.

[0081] According to some embodiments of the present invention, such as Figure 5 and Figure 7 As shown, the first connecting segment 43 may have a first mounting hole 46, and the second connecting segment 52 may have a second mounting hole 55, with the first mounting hole 46 and the second mounting hole 55 being configured correspondingly.

[0082] The first connecting segment 43 may have a first mounting hole 46, and the second connecting segment 52 may have a second mounting hole 55. Both the first mounting hole 46 and the second mounting hole 55 may be threaded holes, and there may be multiple first mounting holes 46 and multiple second mounting holes 55. Multiple first mounting holes 46 and multiple second mounting holes 55 are assembled one-to-one. By passing bolts or screws through the first mounting holes 46 and the second mounting holes 55 simultaneously, the first connecting segment 43 and the second connecting segment 52 can be fixedly assembled, thereby fixing the first mounting frame 41 and the second mounting frame 51.

[0083] Therefore, by providing the first mounting hole 46 and the second mounting hole 55, the first connecting section 43 and the second connecting section 52 can be fixedly assembled by bolts passing through the first mounting hole 46 and the second mounting hole 55, thereby achieving a fixed connection between the power control section 400 and the sensor processing section 500.

[0084] According to some embodiments of the present invention, such as Figure 6 As shown, the first damping element 600 can be fitted onto the outside of the second mounting frame 51.

[0085] The first vibration damping member 600 is sleeved on the outside of the second mounting frame 51. For example, the first vibration damping member 600 can be sleeved at one end and the middle of the second mounting frame 51, but the invention is not limited to this. For example, the first vibration damping member 600 can be sleeved at other positions on the outside of the second mounting frame 51, as long as the first vibration damping member 600 is sleeved on the outside of the second mounting frame 51. Thus, the first vibration damping member 600 sleeved on the outside of the second mounting frame 51 can buffer and dampen the sensor processing section 500, thereby achieving the effect of buffering and damping the drilling directional probe 1000.

[0086] According to some embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9 As shown, the sensor processing section 500 may further include a second circuit board 56 and multiple sensors 57. The second circuit board 56 and multiple sensors 57 may be disposed on the second mounting frame 51. The second circuit board 56 is connected to the multiple sensors 57. The second circuit board 56 is connected to the first circuit board 42 and also to the second connection assembly 300.

[0087] The sensor processing section 500 may further include a second circuit board 56 and multiple sensors 57. For example, the sensors 57 may be multiple accelerometer sensors 57 and multiple fluxgate sensors 57. For instance, there may be three accelerometer sensors 57 and three fluxgate sensors 57. However, the invention is not limited to this; the number of sensors 57 may be six or more, and the sensors 57 may be of other types, as long as the sensor processing section 500 has multiple sensors 57. The second circuit board 56 may include a sensor processing circuit board and a control circuit board. The second circuit board 56 and the multiple sensors 57 may both be located on the second mounting frame 51. For example, the second circuit board 56 may be located in the middle of the second mounting frame 51, and the multiple sensors 57 may be located at both ends of the second mounting frame 51. However, the invention is not limited to this; the second circuit board 56 and the multiple sensors 57 may also be located in other positions on the second mounting frame 51, as long as the second circuit board 56 and the multiple sensors 57 are all located on the second mounting frame 51.

[0088] The second circuit board 56 is communicatively connected to multiple sensors 57, for example, the second circuit board 56 and the multiple sensors 57 are all connected by wire harnesses. The second circuit board 56 is communicatively connected to the first circuit board 42 and also to the second connection assembly 300, for example, the second circuit board 56 and the first circuit board 42 can be connected by wire harnesses. The second circuit board 56 is connected to the second connection assembly 300, for example, the second circuit board 56 and the second connection assembly 300 can be connected by wire harnesses.

[0089] Therefore, the sensor processing sub 500, including a second circuit board 56 and multiple sensors 57, can be mounted on the second mounting frame 51, enabling the sensor processing sub 500 to detect downhole conditions. Furthermore, the second circuit board 56 is connected to both the second circuit board 42 and the second connection assembly 300, allowing communication between the sensor processing sub 500 and the power control sub 400, thereby enabling communication between the first connection assembly 200 and the second connection assembly 300.

[0090] According to some embodiments of the present invention, such as Figure 3 As shown, the second connection assembly 300 may include: a second connection sleeve 31, a second connection end 32, and a second fixed shaft 33. The second connection sleeve 31 may be sleeved on the outside of the second fixed shaft 33. The second connection sleeve 31 is fixedly connected to the other end of the pressure-resistant tube 100. The second fixed shaft 33 is fixedly connected to the second mounting frame 51. The second connection end 32 is fixed at the end of the second fixed shaft 33 away from the pressure-resistant tube 100 and is connected to the sensor processing section 500. The second connection end 32 is adapted to communicate with a second external device.

[0091] The second connecting sleeve 31 can be made of a high-strength, corrosion-resistant metal material, such as beryllium copper, which can improve its high-temperature resistance and corrosion resistance. However, the invention is not limited to this; the second connecting sleeve 31 can also be made of other materials, as long as it is made of a high-strength, corrosion-resistant material. Similarly, the second fixed shaft 33 can be made of a high-strength, non-conductive metal material, such as beryllium copper, which can improve its high-temperature resistance and corrosion resistance. However, the invention is not limited to this; the second fixed shaft 33 can also be made of other materials, as long as it is made of a high-strength, non-conductive material.

[0092] The second connecting sleeve 31 can be sleeved on the outside of the second fixed shaft 33. The second connecting sleeve 31 is fixedly connected to the other end of the pressure-resistant tube 100. For example, the second connecting sleeve 31 and the pressure-resistant tube 100 can be threaded together. However, the present invention is not limited to this. The second connecting sleeve 31 and the pressure-resistant tube 100 can also be connected in other ways, as long as the second connecting sleeve 31 and the pressure-resistant tube 100 are fixedly connected. For example, the outer peripheral wall of the second connecting sleeve 31 has an external thread, and the inner peripheral wall of the pressure-resistant tube 100 has an internal thread. The external thread of the second connecting sleeve 31 and the internal thread of the pressure-resistant tube 100 are engaged to fix the second connecting sleeve 31 and the pressure-resistant tube 100.

[0093] A second sealing element 311 can be provided between the second connecting sleeve 31 and the pressure-resistant pipe 100 for sealing. The second sealing element 311 can be annular in structure, sleeved on the outside of the second connecting sleeve 31, and located between the second connecting sleeve 31 and the pressure-resistant pipe 100. The second sealing element 311 can seal the gap between the second connecting sleeve 31 and the pressure-resistant pipe 100. However, the present invention is not limited to this, and the second sealing element 311 can also be other types of sealing elements, as long as the second sealing element 311 can achieve the sealing function.

[0094] The second fixed shaft 33 is fixedly connected to the second mounting frame 51. For example, the second fixed shaft 33 and the second mounting frame 51 can be fixedly connected by bolts, or the second fixed shaft 33 and the second mounting frame 51 can be connected by snap-fit, or the second fixed shaft 33 and the second mounting frame 51 can be connected by adhesive.

[0095] like Figure 6 and Figure 10 As shown, the second fixed shaft 33 may also be provided with a positioning recess 3, and the second mounting frame 51 may be provided with a positioning protrusion 58. The positioning protrusion 58 is fitted into the positioning recess 3 to prevent the second fixed shaft 33 and the second mounting frame 51 from rotating relative to each other in the circumferential direction.

[0096] The second connecting end 32 is fixed to the end of the second fixed shaft 33 away from the pressure-resistant tube 100, and the second connecting end 32 is communicatively connected to the sensor processing section 500. For example, the second connecting end 32 is communicatively connected to the second circuit board 56 of the sensor processing section 500, and the second connecting end 32 can be connected to the second circuit board 56 via a wire harness. The second connecting end 32 can also be communicatively connected to a second external device, for example, the second connecting end 32 can be plugged into a second external device, which can be a gamma probe.

[0097] Therefore, by fitting the second connecting sleeve 31 around the outside of the second fixed shaft 33, and fixing the second connecting sleeve 31 to the other end of the pressure-resistant tube 100, and fixing the second fixed shaft 33 to the second mounting frame 51, the connection between the second connecting assembly 300 and the sensor processing section 500 can be realized. The second connecting end 32 is fixed to the second fixed shaft 33 and connected to the sensor processing section 500, enabling communication between the second connecting assembly 300 and the sensor processing section 500. The second connecting end 32 also enables communication between the second connecting assembly 300 and the second external device.

[0098] According to some embodiments of the present invention, such as Figure 3As shown, the second connecting sleeve 31 may have a first limiting surface 34, and the second fixed shaft 33 may have a second limiting surface 35. The first limiting surface 34 and the second limiting surface 35 are arranged opposite to each other along the axial direction of the second connecting assembly 300, and a buffer pad 36 is provided between the first limiting surface 34 and the second limiting surface 35.

[0099] Along the axial direction of the second connecting assembly 300, a first limiting surface 34 can be formed on the end face of the second connecting sleeve 31 near the second fixed shaft 33, and a second limiting surface 35 can be formed on the end face of the second fixed shaft 33 near the second connecting sleeve 31. The first limiting surface 34 and the second limiting surface 35 are arranged opposite each other along the axial direction of the second connecting assembly 300. A buffer pad 36 can be provided between the first limiting surface 34 and the second limiting surface 35. For example, the buffer pad 36 can be a rubber pad, but the present invention is not limited to this, as long as the buffer pad 36 can play a buffering role. Thus, by forming a first limiting surface 34 on the second connecting sleeve 31, forming a second limiting surface 35 on the second fixed shaft 33, and providing a buffer pad 36 between the first limiting surface 34 and the second limiting surface 35, the second connecting assembly 300 can play a buffering and vibration reduction role, thereby further improving the buffering and vibration reduction effect of the drilling directional probe 1000.

[0100] According to some embodiments of the present invention, such as Figure 3 As shown, the second connection assembly 300 may further include: a grounding ring 37, which is located inside the second connecting sleeve 31 and sleeved on the outside of the second fixed shaft 33, and the grounding ring 37 is in contact with both the second fixed shaft 33 and the second connecting sleeve 31.

[0101] The grounding ring 37 can be located inside the second connecting sleeve 31, and the grounding ring 37 is sleeved on the outside of the second fixed shaft 33. The grounding ring 37 is in contact with both the second fixed shaft 33 and the second connecting sleeve 31, and the grounding ring 37 can be interference-fitted with both the second fixed shaft 33 and the second connecting sleeve 31. Thus, both the second fixed shaft 33 and the second connecting sleeve 31 can be grounded, ensuring good grounding of the drilling directional probe 1000.

[0102] Furthermore, the ground wire can be fixedly installed on the second fixed shaft 33 by bolts or screws, so that both the second fixed shaft 33 and the second connecting sleeve 31 are grounded.

[0103] According to some embodiments of the present invention, such as Figure 3 and Figure 10 As shown, the outer peripheral wall of the second connecting sleeve 31 may be formed with a positioning surface 38, which is parallel to the sensor of the sensor processing section 500.

[0104] The outer peripheral wall of the second connecting sleeve 31 may have a positioning surface 38. For example, the positioning surface 38 may be located at the end of the outer peripheral wall of the second connecting sleeve 31, but the present invention is not limited thereto. The positioning surface 38 may be located at other positions on the outer peripheral wall of the second connecting sleeve 31, as long as the positioning surface 38 is located on the outer peripheral wall of the second connecting sleeve 31. The positioning surface 38 is parallel to one of the multiple sensors of the sensor processing section 500. The positioning surface 38 may be parallel to the zero-position surface of the acceleration sensor of the sensor processing section 500, marking the zero position of the tool face of the drilling directional probe 1000.

[0105] Therefore, by providing a positioning surface 38 on the outer peripheral wall of the second connecting sleeve 31, and with the positioning surface 38 being parallel to one of the multiple sensors in the sensor processing section 500, the zero position of the tool face of the drilling directional probe 1000 can be identified, which facilitates the calibration of the drilling directional probe 1000 and the mechanical position zeroing work before running it into the well, thereby ensuring the working reliability of the drilling directional probe 1000.

[0106] According to some embodiments of the present invention, such as Figure 3 As shown, the inner peripheral wall of the second connecting sleeve 31 may have a positioning groove 39, and the outer peripheral wall of the second fixed shaft 33 is provided with a positioning boss 30. The positioning boss 30 is assembled in the positioning groove 39 so that the positioning surface 38 is parallel to the sensor of the sensor processing section 500.

[0107] The inner peripheral wall of the second connecting sleeve 31 may have a positioning groove 39, and the outer peripheral wall of the second fixed shaft 33 may have a positioning boss 30. The shape of the positioning boss 30 is adapted to the shape of the positioning groove 39. For example, the positioning boss 30 can be a positioning key. The positioning groove 39 and the positioning boss 30 can be arranged opposite to each other, and the positioning boss 30 is assembled in the positioning groove 39. The positioning boss 30 being assembled in the positioning groove 39 can restrict the circumferential rotation of the second connecting sleeve 31 relative to the second fixed shaft 33, thereby ensuring that the positioning surface 38 is parallel to one of the multiple sensors of the sensor processing section 500, and achieving flush positioning of the positioning surface 38 with one of the multiple sensors of the sensor processing section 500.

[0108] Therefore, by providing a positioning groove 39 on the inner peripheral wall of the second connecting sleeve 31 and a positioning boss 30 on the outer peripheral wall of the second fixed shaft 33, and with the positioning boss 30 fitted into the positioning groove 39, the circumferential rotation of the second connecting sleeve 31 relative to the second fixed shaft 33 can be restricted, thereby making the positioning surface 38 parallel to one of the multiple sensors of the sensor processing section 500. This facilitates the identification of the zero position of the tool face of the drilling directional probe 1000, and makes it convenient for the calibration of the drilling directional probe 1000 and the mechanical position zeroing work before running it into the well, thus ensuring the stability and reliability of the drilling directional probe 1000.
