[0051] This embodiment provides an oil drill pipe tag and related oil drilling tools. Although the drawings show exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] The utility model embodiment provides a petroleum drill pipe label, referring to Figure 1 , Figure 3a , Figure 3b and Figure 4 As shown, including:

[0053] Encapsulating shell 1, supporting structure 2 and electronic tag 3;

[0054] The electronic tag 3 includes a columnar embryo 31 and a chip 32. An antenna is disposed on the surface of the embryo 31. The chip 32 is packaged at one end of the embryo 31. The chip 32 is electrically connected to the antenna.

[0055] The supporting structure 2 is provided with a placement groove 21 on the side, and the electronic tag 3 is embedded in the placement groove 21 and sealed;

[0056] The supporting structure 2 is disposed in the packaging shell 1 .

[0057] Reference Figure 2 As shown, the packaging shell 1 includes a metal upper shell 11 and a metal lower shell 14. The metal upper shell 11 is a circular shell with a hollow top and an inner tightening thread 12 on the inner surface. The metal lower shell 14 is a solid shell with a bottom and an outer annular side surface provided with an outer tightening thread 15. The inner tightening thread 12 and the outer tightening thread 15 can be tightly tightened to fix the metal upper shell 11 and the metal lower shell 14 together to protect their internal structures.

[0058] Metal knurling 13 may be provided on the outside of the metal upper shell 11. Similarly, metal knurling 16 may be provided on the outside of the metal lower shell 14. The function of the metal knurling 16 is to firmly combine the drill pipe label with the oil drilling tool in an interference fit manner when the drill pipe label is installed in the opening of the oil drilling tool.

[0059] In one embodiment, one of the metal upper shell 11 and the metal lower shell 14 can also be provided with knurling. For example, the metal upper shell 11 can be provided with knurling, while the metal lower shell 14 is not provided with knurling, or vice versa.

[0060] The material of the package shell 1 is metal, for example, FF901 alloy can be selected. FF901 alloy is a high-strength, corrosion-resistant alloy material composed of nickel, chromium, molybdenum, niobium and other elements. It has excellent corrosion resistance and can remain stable for a long time in harsh environments such as high temperature, high pressure, strong acid and strong alkali. At the same time, it also has high mechanical strength and good machinability, which can meet the needs of various industrial fields. The material of the package shell 1 includes but is not limited to FF901 alloy, which can be determined according to the actual use environment. For example, other metal materials that are resistant to high temperature, high pressure, corrosion, etc. can also be used, such as: titanium alloy, stainless steel, etc.

[0061] Reference Figure 3a and Figure 3c As shown, the support structure 2 is in the shape of a cylinder, and a placement groove 21 is provided on the side of the support structure 2 for placing the electronic tag 3. Since the electronic tag 3 is placed inside the support structure 2, the polarization direction of the electronic tag 3 is clear, so a symbol mark 22 can be set on the top of the support structure 2, such as a concave arrow mark, to mark the polarization direction of the internal electronic tag 3. An annular step 23 is also provided on the support structure 2, for example, the annular step 23 is set at a position one-third of the distance from the upper surface of the support structure 2.

[0062] Reference Figure 3a and Figure 3b As shown, the bottom of the support structure 2 is provided with a cut corner 24, which is used to apply high-temperature sealant in the angle space formed by the cut corner 24 and the inner wall of the metal lower shell 14 when the support structure 2 is assembled, so as to ensure the sealing of the internal structure of the packaging shell 1 and the firmness of the connection between the support structure 2 and the packaging shell 1. At the same time, it is more conducive to the upper and lower alignment of the support structure 2 and the metal lower shell 14 when they are combined, which is convenient for assembly.

[0063] The support structure 2 is made of a special modified material with high pressure resistance and temperature resistance and additives, such as adding heat-resistant and pressure-resistant ceramics and metal elements such as potassium and aluminum to promote the grain growth of the modified material, and then adding high-strength materials to improve its compressive performance. In addition, stabilizers are added to form a more stable tetragonal special modified material polycrystal to improve its temperature and pressure resistance.

[0064] Reference Figure 4 As shown, the electronic tag 3 includes an embryo 31 and a chip 32, wherein the embryo 31 is a dielectric ceramic embryo, and the chip 32 is a chip packaged in a DFN (Dual Flat No-lead Package) manner. For example, the dielectric ceramic embryo uses a dielectric ceramic with a high dielectric constant, and its dielectric constant ranges from 120 to 180 farads / meter, which can efficiently generate inductance and capacitance in an electromagnetic oscillation circuit. The surface of the embryo 31 is provided with an electronic circuit of the electronic tag 3, which is made of conductive silver paste printing with excellent temperature resistance. The packaged chip of the electronic tag 3 complies with the GB / T 29768 protocol or the optional ISO / IEC 18000-6C EPC Class1 GEN2 protocol, and supports SM7 national encryption. Its operating frequency covers 920 to 925 MHz and can adapt to 902 to 928 MHz.

[0065] Before the electronic tag 3 is placed in the placement groove 21 on the side of the support structure 2, a filler made of polymer silicone is pre-filled in the placement groove 21. After the electronic tag 3 is placed, the filler made of polymer silicone is encapsulated, so that the electronic tag 3 is completely wrapped by the filler made of polymer silicone and fixed in the placement groove 21 without moving. The filler made of polymer silicone has the characteristics of high and low temperature resistance, weather resistance, corrosion resistance, radiation resistance, electrical insulation performance and physiological inertness, and also has the advantages of low surface tension, low surface energy, low hygroscopicity, low dielectric constant, low stress, low toxicity, vibration reduction, environmental protection, and flame retardancy, so as to effectively ensure that the electronic tag 3 embedded in the support structure 2 can work stably and is not affected by the external adverse environment, and effectively ensure the performance of the built-in anti-metal ceramic electronic tag 3.

[0066] In addition, refer to Figure 1 As shown, the oil drill pipe tag also includes a sealing ring 4. Specifically, referring to Figure 1 , Figure 5a and Figure 5b As shown, the sealing ring includes a first sealing ring 41 and a second sealing ring 42, the purpose of which is to ensure the sealing of the internal structure of the package shell 1 after the drill pipe tag is assembled. The first sealing ring 41 is arranged at the bottom of the external thread of the metal lower shell 14, ensuring the sealing of the connection between the external thread of the metal lower shell 14 and the internal thread of the upper shell, and the second sealing ring 42 is arranged on the annular step 23 of the support structure 2, ensuring the sealing between the metal upper shell 11 (the top hollow part) and the support structure.

[0067] The first sealing ring 41 and the second sealing ring 42 can use FF902 perfluoroether rubber O-rings, for example. FF902 fluoroether rubber O-rings have high temperature resistance, chemical solvent resistance, high cleanliness and corrosion resistance (including resistance to corrosion of more than 1,600 chemical products such as strong acids, strong alkalis, ethers, ketones, esters, nitrogen-containing compounds, hydrocarbons, alcohols, aldehydes, oils, steam, amino compounds, etc.), and high temperature resistance can reach 320°C. The materials of the first sealing ring 41 and the second sealing ring 42 include but are not limited to fluoroether rubber, and other fluororubbers, silicone rubbers, etc. with superior performance can also be used according to the actual use environment, and the embodiments of the utility model are not limited thereto.

[0068] The utility model also provides an oil drilling tool provided with the oil drilling rod label as described above, the side wall of the drill rod of the oil drilling tool is provided with a hole, and the assembled oil drilling rod label (refer to Figure 6 is installed in the hole.

[0069] The oil drill pipe label can be pre-installed on the side of the drill pipe using the following method: first fix the oil drill tool, select the specifications of the milling cutter according to the process requirements, and use the milling cutter to open a hole in the oil drill tool. According to experience, the outer diameter of the hole opened should be less than or equal to the outer diameter of the oil drill pipe label 0.3mm. If the outer diameter is too small, the oil drill pipe label will not be able to be embedded in the oil drill tool.

[0070] After the milling cutter drills a hole on the oil drilling tool, a small convex spot will be left in the middle of the bottom of the hole due to the milling cutter operation. At this time, it needs to be polished flat, for example, it can be manually polished with a portable pneumatic or electric small grinding wheel gun. If the above small convex spot is not polished, the oil drill pipe label cannot be fully in contact with the bottom of the hole. In addition, apply special sealant to the bottom of the hole and the hole wall to expand the position of the hole into a small trumpet (a few wires larger than the outer diameter of the oil drill pipe label).

[0071] When embedding the oil drill pipe label, first place the oil drill pipe label steadily at the hole mouth, and use a tool to steadily knock the oil drill pipe label into the flat mouth of the hole, so as to avoid the risk of tilting the oil drill pipe label due to direct knocking. When the surface of the oil drill pipe label is flush with the surface of the oil drill tool, use a cylindrical tool (whose surface diameter is the same as the diameter of the oil drill pipe label) to knock the oil drill pipe label completely into the hole, and finally apply special glue at the hole mouth to completely seal the oil drill pipe.

[0072] Obviously, those skilled in the art can make various changes to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications.
