[0020] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.
[0021] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.
[0022] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1-6 As shown, the heat-dissipating RFID downhole sealing device includes a drill pipe 1, with an upper connecting end 2 fixedly connected to the top of the drill pipe 1 and a lower connecting end 3 fixedly connected to the bottom of the drill pipe 1. The drill pipe 1 has a vertically penetrating guide channel 5 inside. An RFID antenna 10 is fixedly installed on the right side inside the drill pipe 1, and an RFID reader 11 is fixedly installed on the left side inside the drill pipe 1. A PLC control board 12 located below the RFID reader 11 is fixedly installed on the left side inside the drill pipe 1. The RFID reader 11, RFID antenna 10, and PLC control board 12 are connected for signal transmission. A first heat dissipation component 7, which is attached to the RFID antenna 10, is fixedly installed inside the inner wall of the drill pipe 1. A second heat dissipation component 8, which is attached to the RFID reader 11 and the PLC control board 12, is fixedly installed inside the inner wall of the drill pipe 1.
[0023] After the drilling fluid enters the drill pipe 1, it flows into the first heat dissipation component 7 and the second heat dissipation component 8, respectively, to cool the RFID reader 11, RFID antenna 10 and PLC control board 12. This effectively improves the efficiency of heat exchange and prevents the circulating water with too fast a flow rate from failing to form a stable heat transfer interface, which would otherwise reduce the efficiency of heat exchange. Without adding extra electrical appliances, the continuously circulating drilling fluid can be used to cool the RFID downhole plugging equipment, avoiding damage to its internal components in a high-temperature environment and reducing the maintenance rate of the reader.
[0024] The aforementioned heat-dissipating RFID downhole leak sealing equipment can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 4As shown, the first heat dissipation component 7 includes a first mounting frame 71, which is fixedly installed inside the drill pipe 1. The first mounting frame 71 is located to the right of the RFID antenna 10. Several first heat exchange plates 72 are provided at left and right intervals between the upper and lower sides of the first mounting frame 71. A first heat exchange block 73 that contacts the right side of the RFID antenna 10 is fixedly installed on the outer side of the first heat exchange plate 72. A connecting pipe 74 that penetrates to the outer side of the first mounting frame 71 is fixedly connected to both the upper and lower sides of the first heat exchange plate 72. The number of connecting pipes 74 matches the number of first heat exchange plates 72. The upper end of the connecting pipe 74 is connected to a first water distribution pipe 75. The top of the first water distribution pipe 75 is connected to a first guide plate 76 that extends into the guide channel 5. The lower end of the connecting pipe 74 is connected to a first water collection pipe 77. The bottom of the first water collection pipe 77 is connected to a first drain pipe 78 that penetrates into the guide channel 5.
[0025] After the drilling fluid enters the drill pipe 1, some of the drilling fluid will enter the first water distribution pipe 75 through the first guide plate 76, and guide the drilling fluid into the first heat exchange plate 72 to reduce the temperature of the first heat exchange plate 72 and the first heat exchange block 73. Thus, the RFID antenna 10 is cooled by the cooled first heat exchange plate 72 and the first heat exchange block 73, so as to prevent the RFID antenna 10 from being damaged in the high temperature environment. The drilling fluid flows back into the guide channel 5 through the first water collection pipe 77 from the first drain pipe 78 and completes the subsequent drill bit cooling cycle.
[0026] Example 3: As shown in the attached document Figure 5 As shown, the second heat dissipation assembly 8 includes a second mounting frame 81 and a third mounting frame 82. The second mounting frame 81 is installed on the right side of the RFID reader / writer 11, and the third mounting frame 82 is installed on the right side of the PLC control board 12. A second heat exchange plate 84 is fixedly installed inside both the second mounting frame 81 and the third mounting frame 82. A second heat exchange block 85 is fixedly installed on the outside of both the second heat exchange plate 84. The second mounting frame 81 and the third mounting frame 82 are connected by a drain pipe 83. A second water distribution pipe 86 connected to the second heat exchange plate 84 is fixedly installed above the second mounting frame 81. A second guide plate 87 extending into the guide channel 5 is connected to the top of the second water distribution pipe 86. A second water collection pipe 89 connected to the second heat exchange plate 84 located below is fixedly installed below the third mounting frame 82. A second drain pipe 810 extending into the guide channel 5 is connected to the bottom of the second water collection pipe 89.
[0027] After the drilling fluid enters the drill pipe 1, some of the drilling fluid will be guided into the second heat exchange plate 84 through the second guide plate 87 and the second water distribution pipe 86 for heat exchange, thereby reducing the temperature of the second heat exchange plate 84 and the second heat exchange block 85. The RFID reader 11 and the PLC control board 12 will be cooled by the cooled second heat exchange plate 84 and the second heat exchange block 85. The drilling fluid will then flow back into the guide channel through the second water collection pipe 89 and the second drain pipe 810.
[0028] Example 4: As shown in the appendix Figure 5 As shown, both the first guide plate 76 and the second guide plate 87 have filter screens 88 fixedly installed inside. The filter screens 88 filter drilling fluid impurities to prevent blockage of subsequent pipelines and thus reduce cooling efficiency.
[0029] Example 5: As shown in the attached document Figure 1-3 As shown, side drain ports 4, which are connected to the flow guide channel 5, are provided on both the left and right sides of the drill pipe 1. A discharge control mechanism 9, which can open and close the side drain port 4, is provided inside the drill pipe 1 at each position of the side drain port 4. By setting the side drain ports 4, the water accumulated inside can be discharged when needed, thereby maintaining the normal operation of the equipment and preventing water from damaging RFID tags or electronic components.
[0030] Example 6: As attached Figure 6 As shown, the emission control mechanism 9 includes a hydraulic cylinder 91, a telescopic rod 92 on the lower side of the hydraulic cylinder 91, a connecting block 93 fixedly installed at the bottom of the telescopic rod 92, and a valve plate 94 capable of sealing the side drain port 4 installed on the lower side of the connecting block 93. By controlling the extension or retraction of the telescopic rod 92 through the hydraulic cylinder 91, the side drain port 4 is opened or closed. A groove adapted to the valve plate 94 is formed on the inner bottom wall of the side drain port 4, and a sealing gasket that fits against the valve plate 94 is fixedly installed inside the groove. The sealing gasket improves the sealing effect on the side drain port 4. Example 7: As attached Figure 6 As shown, guide rods 95 located on both sides of the telescopic rod 92 are fixedly installed on the top of the connecting block 93. A guide block 96, which is sleeved on the outside of the guide rod 95, is movably installed on the outside of the telescopic rod 92. The guide block 96 is fixedly installed inside the drill pipe 1. The cooperation between the guide block 96 and the guide rod 95 can improve the stability of the valve plate 94 when it moves.
[0031] Example 8: As attached Figure 2 , 3As shown, a vertical valve 6, capable of blocking the flow channel 5, is installed on the inner side of the lower part of the drill pipe 1. The PLC control board 12 is connected to the vertical valve 6. By adjusting the opening of the vertical valve 6, the flow rate of the downhole medium can be controlled to meet different operational needs. When it is necessary to stop the flow of the downhole medium, the vertical valve 6 can be closed to completely cut off the medium. This helps prevent medium leakage and accidents during equipment maintenance, repair, or emergencies.
[0032] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
