Technical Field
[0001] This utility model relates to the field of oil drill pipe management technology, and in particular to an RFID embedded structure for deep well electronic tag drill pipe joints. Background Technology
[0002] RFID tags for drill pipe joints are a wireless radio frequency identification technology used in oil drill pipe management. RFID tags store a unique identifier and related information for the drill pipe. A reader communicates with the tag by emitting radio frequency signals, reading or writing data from the tag. When a tag enters the reader's working area, it receives the signal and returns the stored data to the reader. The reader then transmits the data to a data processing system for processing and analysis. This allows for accurate recording of various drill pipe information, avoiding errors and omissions caused by manual recording. It enables precise statistics on the quantity and status of drill pipes, helping companies achieve refined inventory management, reducing inventory backlog and waste. Furthermore, with continuous technological advancements, RFID tags offer higher storage capacity, faster read / write speeds, and longer identification distances to meet more complex drill pipe management needs.
[0003] Specially designed RFID chips and tags can withstand the metal interference, high temperature, and high pressure encountered by drill pipes downhole. The connection mechanism that attaches them to the drill pipe is particularly important. In existing technologies, a pre-reserved groove is machined in the drill pipe joint, the tag is embedded, and then filled and sealed with adhesive. The surface is polished to reduce fluid resistance and wear. However, after long-term use, the adhesive will gradually wear down until it can no longer fix the tag in the pre-reserved groove. As the drill pipe rotates, the tag will be thrown off and lost, resulting in reduced safety and shortened service life. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 An embodiment of this utility model is provided: the RFID embedded structure of the deep well electronic tag drill pipe joint includes a rod body 1, the outer wall of the rod body 1 is provided with a quick-installation mechanism 2, the quick-installation mechanism 2 is used for quick installation and connection of the remaining structure, and the inner wall of the rod body 1 is fixedly connected with a cooling mechanism 3, the cooling mechanism 3 is used to cool the inside of the structure.
[0033] The quick-installation mechanism 2 includes an installation groove 201, which is located on the outer wall of the rod 1. A hollow column 203 is threadedly connected to the inner wall of the installation groove 201. A label protection shell 204 is located on the outer wall of the hollow column 203. A guide groove 207 is provided on the rear side of the label protection shell 204. A connecting component 205 is provided on the inner wall of the guide groove 207. An auxiliary component 206 is fixedly connected to the front side of the label protection shell 204. The connecting component 205 includes a sliding groove 2052, which is located on the upper and lower sides of the inner wall of the guide groove 207. A slot 2051 is provided in the middle of the inner wall of the guide groove 207. A sliding block 2053 is slidably connected to the inner wall of the sliding groove 2052. A connecting block 2054 is fixedly connected to the outer wall of the hollow column 203. A reset component 202 is fixedly connected to the front side of the connecting component 205.
[0034] Specifically, the card slot 2051 is formed in the middle of the inner wall of the guide groove 207. Its shape and size match the connecting block 2054 and are used to accommodate and fix the connecting block 2054, thereby realizing the connection between the label protective shell 204 and the hollow column 203. The slide groove 2052 is set on the upper and lower sides of the inner wall of the guide groove 207. The slide groove 2052 provides a track for the movement of the sliding block 2053, ensuring that the sliding block 2053 can slide smoothly in a predetermined direction. The sliding block 2053 is slidably connected to the inner wall of the slide groove 2052 and can slide in the slide groove 2052 under the action of external force. The movement of the sliding block 2053 can control the connection and separation of the connecting block 2054 and the slot 2051, thereby realizing the quick installation and removal of the label protective shell 204. The connecting block 2054 is fixedly connected to the outer wall of the hollow column 203. When the label protective shell 204 is installed on the hollow column 203, the connecting block 2054 will slide along the guide groove 207 and finally enter the slot 2051 to achieve cooperation and fixation with the sliding block 2053.
[0035] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 The cooling mechanism 3 includes a liquid tank 301, which is fixedly connected to the inner wall of the rod 1. The right side of the liquid tank 301 is connected to an inlet pipe 302, the front end of the inlet pipe 302 is connected to a cooling pipe 304, the left end of the cooling pipe 304 is connected to a return pipe 303, a filter assembly 306 is fixedly connected to the middle of the inner wall of the liquid tank 301, a one-way flow assembly 305 is fixedly connected to the right side of the inner wall of the liquid tank 301, and a reset assembly 202 is threadedly connected to the outer wall of the label protective shell 204. The one-way flow assembly 305 includes a spring column 3051, the right end of the spring column 3051 is fixedly connected to the right side of the inner wall of the liquid tank 301, and a baffle 3052 is fixedly connected to the left end of the spring column 3051.
[0036] Specifically, when coolant flows from the inlet pipe 302 into the tank 301, the coolant pressure pushes the baffle 3052 to the right, compressing the spring column 3051 and opening the channel to allow the coolant to smoothly enter the tank 301. When the coolant stops flowing or shows a backflow tendency, the elastic force of the spring column 3051 causes the baffle 3052 to move to the left, tightly fitting against the channel opening and preventing coolant backflow. When coolant flows from the inlet pipe 302 into the cooling pipe 304, it absorbs the heat generated inside the drill pipe joint, thus raising its own temperature. Subsequently, the heated coolant flows back to the tank 301 through the return pipe 303, completing one heat exchange cycle. Through continuous circulation, the cooling pipe 304 can continuously remove heat from inside the drill pipe joint, achieving the purpose of cooling.
[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The auxiliary component 206 includes a loop antenna 2062, the rear side of which is fixedly connected to the front side of the label protective shell 204. A rotating groove 2061 is provided in the middle of the front side of the loop antenna 2062. The filter component 306 includes a support plate 3062, which is fixedly connected to the middle of the inner wall of the liquid tank 301. A filter plate 3061 is fixedly connected to the middle of the inner wall of the support plate 3062.
[0038] Specifically, the loop antenna 2062 enhances the antenna's radiation and reception capabilities, expands the signal coverage, and enables RFID tags to communicate with reading and writing devices at greater distances, improving data transmission efficiency and reliability. The slot 2061 provides operating space for disassembly tools. When maintenance or replacement of the RFID tag or tag protective shell 204 is required, maintenance personnel can insert special tools into the slot 2061 and remove the tag protective shell 204 from the drill pipe joint by rotating or pushing the tools, thus improving the efficiency of maintenance and replacement.
[0039] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 5 The reset assembly 202 includes a screw 2024, which is threaded onto the outer wall of the label protective shell 204. A hollow tube 2021 is provided on the outer wall of the screw 2024. A sliding rod 2023 is slidably connected to the inner wall of the hollow tube 2021. A reset spring 2022 is fixedly connected to the front end of the sliding rod 2023. The bottom end of the return pipe 303 is connected to the top of the liquid tank 301. The outer wall of the cooling pipe 304 is in contact with the inner wall of the label protective shell 204.
[0040] Specifically, after the coolant completes heat exchange in the cooling pipe 304 and absorbs the heat inside the drill pipe joint, it flows back to the liquid tank 301 through the return pipe 303. When the reset assembly 202 is subjected to external force, the sliding rod 2023 slides forward along the inner wall of the hollow tube 2021. At this time, the reset spring 2022 is compressed and stores elastic potential energy. When the external force disappears, the reset spring 2022 releases the stored elastic potential energy, pushing the sliding rod 2023 to slide backward and return to its original position, thereby realizing the reset function.
[0041] Working principle: When connecting this device, first align the guide groove 207 on the rear side of the label protective shell 204 with the hollow column 203, and simultaneously align the sliding groove 2052 with the connecting block 2054. Then, press the label protective shell 204 against the hollow column 203, so that the connecting block 2054 can press the sliding block 2053, thereby pressing the sliding rod 2023 to compress the return spring 2022, and then retracting it into the hollow tube 2021 until the outer wall of the connecting block 2054 can fit against the inner wall of the slot 2051. Then, rotate the label protective shell 204, so that the connecting block 2054 rotates relative to the inner wall of the slot 2051. The connecting block 2054 is then separated from the outer wall of the sliding block 2053. At this time, the return spring 2022 will push the sliding rod 2023 to slide backward along the slide groove 2052, thereby limiting the connecting block 2054 in the guide groove 207 for quick installation. Finally, adhesive is filled into the installation groove 201 for sealing. When it is necessary to remove the connecting block 2054, the screw 2024 is turned to loosen and remove the hollow tube 2021. Then, the label protective shell 204 is turned to remove the connecting block 2054 and the hollow column 203 from the guide groove 207.
[0042] When it is necessary to cool the hollow column 203 and thus the label protective shell 204, cooling liquid is first poured into the liquid tank 301. When the rod 1 rotates, the liquid in the liquid tank 301 will surge to one side due to centrifugal force and enter the squeeze baffle 3052, which will compress the spring column 3051 and move it to the right, so that it enters the liquid inlet pipe 302 and then enters the cooling pipe 304 to remove the heat from the outer wall of the cooling pipe 304. Then, due to gravity and the push of the liquid behind, it enters the liquid tank 301 along the return pipe 303 and enters the liquid tank 301. After being filtered by the filter plate 3061, it re-enters the liquid inlet pipe 302.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
