[0025] See also Figure 1 The present application provides an underground wireless communication and power supply integrated device, including a pressure-bearing tube 1 and a protective tube 2. The protective tube 2 is fixedly arranged on the right side of the pressure-bearing tube 1. A plug 3 is fixedly arranged on the left side of the interior of the pressure-bearing tube 1. The plug 3 is used to connect to external instruments. A battery pack 4 is fixedly arranged in the middle of the interior of the pressure-bearing tube 1. A wireless communication unit 5 is arranged on the right side of the interior of the pressure-bearing tube 1. The wireless communication unit 5 includes a communication module 501, a shock absorber 502 and a communication coil 503. The communication coil 503 is fixedly arranged inside the protective tube 2. The shock absorber 502 is fixedly arranged on the left side of the communication coil 503. The communication module 501 is fixedly arranged on the left side of the shock absorber 502. The right side of the communication module 501 is electrically connected to the communication coil 503 through a wire, and the left side of the communication module 501 is electrically connected to the plug 3 through a wire. In the underground wireless communication and power supply integrated device provided by the present application, the plug 3 is used to connect to external instruments, receive data, encode the data, and then send it through the right-end communication coil 503, thereby realizing data migration.

[0026] In the underground wireless communication and power supply integrated device provided by the present application, the pressure tube 1 adopts high-strength TBe2 alloy (beryllium copper alloy) as the base material, which has excellent mechanical strength and corrosion resistance; the outer wall is evenly deposited with a 0.1-0.3mm thick tungsten carbide (WC) coating through a plasma spraying process, forming a double protection system. This design reduces the erosion wear rate of the pressure tube 1 to less than 1 / 5 of that of a traditional stainless steel tube in the extreme erosion environment of underground sand-containing mud (sand content ≤10%), high pressure (≥70MPa) and high flow rate (≥5m / s), extending its service life by more than 3 times, and significantly reducing the frequency of on-site replacement and maintenance costs.

[0027] In the integrated downhole wireless communication and power supply device provided herein, a protective tube 2 is threadedly fixed to the right of a pressure tube 1. The pressure tube 1 and protective tube 2 create a stress-free, sealed environment for the battery pack 4 and communication module 501, and the threaded connection facilitates replacement of internal modules. When an internal module needs to be replaced, only the pressure tube 1 needs to be disassembled. During field use, workers can replace it with simple tools, making this method widely applicable at drilling sites.

[0028] In the integrated underground wireless communication and power supply device provided in this application, a gap is reserved between the pressure-bearing cylinder 1 and the battery pack 4, through which the left-side wire of the communication module 501 is electrically connected to the plug 3. By arranging a through-wire around the periphery of the battery pack 4, this application can realize the left-side data port, and the wiring is simple and convenient, which is easy to maintain.

The overcurrent protection circuit is used to prevent damage to the battery due to excessive current, ensuring safe and stable operation of the system. The fuse circuit can automatically cut off the current in the event of an abnormality, playing a protective role. The backup battery pack is connected in parallel with the overcurrent protection circuit. When the main battery pack fails or is low on power, the backup battery pack can provide power support in a timely manner, ensuring continuous operation of the equipment and further enhancing the reliability and safety of the battery pack.
