[0024] In order to better understand the purpose, structure and function of the present invention, a downhole wireless data receiver of the present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, it shows a downhole wireless data receiver according to an embodiment of the present invention, comprising an electronic circuit assembly 3, an antenna short section assembly 4 and a quartz pressure sensor assembly 5 arranged in sequence from top to bottom, wherein the electronic circuit assembly 3 and the antenna short section assembly 4, and the antenna short section assembly 4 and the quartz pressure sensor assembly 5 are fixedly connected by quick-screw nuts 7.

[0026] In this embodiment, two adjacent short sections are connected by a quick-screw nut. Therefore, when the quartz pressure sensor assembly 5 is not needed during operation, it can be disassembled at any time to meet the instrument operation requirements; this embodiment can meet the requirements of different types of operation modes; the setting of this embodiment greatly improves the reliability of the direct reading system and improves the high utilization rate of the equipment.

[0027] Among them, such as Figure 2 As shown, the left end of the electronic circuit assembly 3 is connected to the single-core plug 26, and the electronic circuit assembly 3 and the antenna short section assembly 4, as well as the antenna short section assembly 4 and the quartz pressure sensor assembly 5 are electrically connected in sequence. The antenna short section assembly 4 is used for electromagnetic coupling connection with the relay station, the quartz pressure sensor assembly 5 is used to test the pressure and temperature parameters of the target layer, and the electronic circuit assembly 3 is used to communicate with the quartz pressure sensor assembly 5 and the electronic circuit assembly 3 and the antenna short section assembly 4.

[0028] In this embodiment, the electronic circuit assembly 3 is powered by a single-core plug 26, and the electronic circuit assembly 3 is used to communicate with the quartz pressure sensor assembly 5 and the antenna short section assembly 4. The quartz pressure sensor assembly 5 is used to test the pressure and temperature parameters of the target layer. The measured pressure and temperature parameters are transmitted to the ground through the single-core plug 26 and the cable, thereby realizing real-time uploading of data; the antenna short section assembly 4 is electromagnetically coupled to the relay station. After the relay station receives the pressure and temperature parameters measured by the bracket short section, the relay station can transmit the received pressure and temperature parameters to the antenna short section assembly 4 through electromagnetic coupling. The pressure and temperature parameters received by the antenna short section assembly 4 are also transmitted to the ground through the single-core plug 26 and the cable, thereby realizing the uploading of the pressure and temperature parameters measured by the bracket short section.

[0029] Existing downhole wireless data receivers lack a quartz pressure sensor assembly, making them incapable of real-time measurement of dynamic pressure, temperature, and other parameters. This application overcomes these shortcomings and achieves real-time measurement of temperature and pressure parameters. Furthermore, the electronic circuit assembly 3 of this application is powered by a single-core plug and cable, thus improving operating time.

[0030] Among them, such as Figure 2 、 Figure 3 As shown, the electronic circuit assembly 3 includes an electronic circuit housing 14 and an electronic circuit 15 arranged in the electronic circuit housing 14. The electronic circuit 15 is used to communicate with the quartz pressure sensor assembly 5 and the antenna short section assembly 4. The electronic circuit housing 14 is threadedly connected to the antenna short section assembly 4 through a quick-screw nut 7; a long female pin 28 is provided at the left end of the electronic circuit 15, and the long female pin 28 is plug-connected to the single-core plug 26. The outer sleeve of the long female pin is provided with an insulating sleeve 27, and the outer sleeve of the insulating sleeve 27 is provided with a grounding component. The grounding component is used to connect the electronic circuit housing 14 and the negative pole of the electronic circuit 15.

[0031] Specifically, the electronic circuit assembly 3 of the present application includes an electronic circuit housing 14 and an electronic circuit 15. The electronic circuit 15 is connected to a single-core plug 26 via a long female pin 28 at its left end. The electronic circuit 15 of the present application is used to communicate with the quartz pressure sensor assembly 5 and the antenna stub assembly 4, for example, to power the quartz pressure sensor assembly 5 and the antenna stub assembly 4. The electronic circuit housing 14 is threadedly connected to the antenna stub assembly 4 via a quick-screw nut 7.

[0032] In this embodiment, an insulating sleeve 27 is provided on the outer sleeve of the long female pin, and a grounding component is provided on the outer sleeve of the insulating sleeve 27. The grounding component is used to connect the electronic circuit housing 14 and the negative pole of the electronic circuit 15. In this embodiment, the grounding is directly introduced into the housing to meet the circuit design requirements.

[0033] Among them, such as Figure 3 As shown, the grounding assembly includes a first grounding assembly 23 and a second grounding assembly 24 sleeved outside the first grounding assembly 23. The first grounding assembly 23 and the second grounding assembly 24 are threadedly connected. The first grounding assembly 23 is threadedly connected to the connecting ring 30. The connecting ring 30 is threadedly connected to the electronic circuit housing 14. The first grounding assembly is connected to the negative pole of the electronic circuit.

[0034] The outer portion of the insulating sleeve 27 is provided with a copper tube 29, and the first grounding assembly 23 is sheathed on the outer portion of the copper tube 29. The copper tube 29 is connected to the negative electrode of the electronic circuit 15. Specifically, the inner wall of the first grounding assembly 23 is designed with a crown structure. The outer circumference of the copper tube 29 directly contacts the inner wall of the first grounding assembly 23 to achieve electrical connection between the copper tube 29 and the first grounding assembly 23. The copper tube 29 is connected to the negative electrode of the electronic circuit 15. The first grounding assembly 23 is threadedly connected to the connecting ring 30, and the connecting ring 30 is threadedly connected to the electronic circuit housing 14, thereby connecting the negative electrode of the electronic circuit to the electronic circuit housing 14.

[0035] A flange is provided at the right end of the second grounding component 24, and a spring pressure piece 25 is sleeved on the second grounding component 24. A shrinking ring is provided at the left end of the spring pressure piece. The inner diameter of the shrinking ring matches the outer diameter of the second grounding component 24, and the inner diameter of the spring pressure piece matches the outer diameter of the flange. A first spring 22 is sleeved on the second grounding component 24 between the spring pressure piece and the connecting ring 30. When the first spring 22 is at its original length, the shrinking ring is located between the flange and the connecting ring 30, and the right end of the spring pressure piece contacts the left end of the electronic circuit 15.

[0036] When the first spring 22 is at its original length, the constricting ring at the left end of the spring pressure plate is positioned between the flange of the second grounding assembly and the connecting ring 30, and the right end of the spring pressure plate contacts the left end of the electronic circuit 15. Therefore, when the electronic circuit expands due to heat, the electronic circuit pushes the spring pressure plate to compress the first spring to the left, thereby providing a buffering effect and preventing hard contact between the electronic circuit and the second grounding assembly. The arrangement of the first spring and spring pressure plate in this embodiment provides a buffering and shock-absorbing effect, and effectively protects the electronic circuit 15 from deformation caused by thermal expansion and contraction.

[0037] During the specific installation, put the insulating sleeve 27 on the position where the electronic circuit and the long female pin 28 match, and then put on the first grounding component, the second grounding component, the first spring and the spring pressure plate in sequence, and then thread the overall structure with the connecting ring 30. After the overall structure is threadedly connected to the connecting ring 30, the electronic circuit is electrically connected to the long female pin.

There is an insulating joint 19, the right end of the insulating joint 19 is deeply inserted into the annular groove and sealed with the annular groove, the left end of the insulating joint 19 is sealed with the first antenna short section 18, and the first antenna short section 18 and the second antenna short section 21 are threadedly connected; the left end of the connecting cable is connected to the electronic circuit 15, the left end of the first antenna short section 18 is threadedly connected to the electronic circuit housing 14 through the quick-screw nut 7, the right end of the connecting cable is electrically connected to the quartz pressure sensor assembly, and the right end of the second antenna short section 21 is threadedly connected to the quartz pressure sensor assembly 5 through the quick-screw nut 7.

The quartz pressure sensor circuit acquisition module 12 is fixed in the outer shell 5, and the left end of the outer shell 5 is threadedly connected to the right end of the second antenna short section 21 through a quick-screw nut 7.

[0044] In this embodiment, the pressure-bearing joint 17 at the right end protects the quartz pressure sensor 9 and the quartz pressure sensor circuit acquisition module 12, mitigating risks associated with pressure-bearing issues within the quartz pressure sensor circuit acquisition module 12. The quartz pressure sensor circuit acquisition module 12 and the quartz pressure sensor 9 are housed within the same housing, minimizing space and shortening wiring. This significantly reduces interference issues associated with long wiring and improves the stability of the quartz pressure sensor's data acquisition performance. Furthermore, a convenient connector module is used between the quartz pressure sensor circuit acquisition module 12 and the quartz pressure sensor 9, effectively avoiding the need for repeated wire soldering during maintenance.
