Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0052] As described in the background section, when drilling using drilling tools, drilling parameters such as rotational speed, drilling pressure, torque, impact vibration, temperature, and annular pressure reflect the drilling operation status. Therefore, timely acquisition of real-time drilling parameters is crucial for adjusting the drilling plan promptly and preventing drilling accidents. However, drilling often involves operations in high-temperature and high-pressure environments. Existing drilling parameter measuring instruments cannot achieve rapid data acquisition and reading in such environments, preventing surface personnel from obtaining real-time drilling parameters and consequently hindering timely adjustments to the drilling plan.

[0053] In response to this, one embodiment of this application provides a drilling device, such as... Figures 1-9 As shown, the drilling equipment includes a monitoring component 100, a drill collar 200, and a drill string 300. One end of the monitoring component 100 is connected to the drill collar 200, and the other end is connected to the drill string 300. The monitoring component 100 includes a hollow drill pipe 110 and an outer cylinder 120 sleeved on the outside of the hollow drill pipe 110. The hollow drill pipe 110 is divided into a liquid guiding section 111, a liquid collecting section 112, and a liquid discharging section 113 along the liquid flow direction. The inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid guiding section 111, and the inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid discharging section 113. A first inlet hole 114 is formed on the pipe wall of the hollow drill pipe 110 corresponding to the liquid guiding section 111, and a second inlet hole 115 is formed on the pipe wall of the hollow drill pipe 110 corresponding to the liquid collecting section 112. The outer wall of the outer cylinder 120 is... The system includes an inlet tank 121, with an inlet tank 124 located at one end near the drill string 300 and an outlet tank 125 located at the other end near the drill collar 200. The inner cavity of the fluid guiding section 111 communicates with the inlet tank 124 via a first inlet hole 114, and the inner cavity of the fluid collecting section 112 communicates with the outlet tank 125 via a second inlet hole 115. A cooling plate is positioned between the inlet tank 124 and the outlet tank 125, with its liquid inlet connected to the inlet tank 124 and its liquid outlet connected to the outlet tank 125. A support plate 128 is located on the side of the cooling plate facing away from the inlet tank 121, and a chip corresponding to a drilling parameter sensor is mounted on the support plate 128. A housing 160 is located on the side of the support plate 128 facing away from the cooling plate.

[0054] The hollow drill rod 110 coincides with the center line of the outer cylinder 120.

[0055] The hollow drill pipe 110 is divided into a liquid guiding section 111, a liquid collecting section 112, and a liquid discharging section 113 along the liquid flow direction, that is, the liquid guiding section 111, the liquid collecting section 112, and the liquid discharging section 113 are connected in sequence. In this application, the liquid flow direction refers to the direction consistent with the liquid flow direction inside the hollow drill pipe 110.

[0056] The liquid collecting section 112 can be divided into a first transition section, a waist section, and a second transition section along the liquid flow direction. Specifically, along the liquid flow direction, the inner diameter of the first transition section gradually decreases, with the inner diameter of the end of the first transition section connecting to the liquid guiding section 111 equal to the inner diameter of the liquid guiding section 111, and the inner diameter of the end of the first transition section connecting to the liquid collecting section 112 equal to the inner diameter of the liquid collecting section 112. Conversely, along the liquid flow direction, the inner diameter of the second transition section gradually increases, with the inner diameter of the end of the second transition section connecting to the liquid collecting section 112 equal to the inner diameter of the liquid collecting section 112, and the inner diameter of the end of the second transition section connecting to the liquid exit section 113 equal to the inner diameter of the liquid exit section 113. That is, the inner cavity of the liquid collecting section 112 can be dumbbell-shaped. Therefore, in this embodiment, the inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid guiding section 111, and the inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid discharging section 113. Specifically, the inner diameter of the middle section of the liquid collecting section 112 is smaller than the inner diameter of the liquid guiding section 111, and the inner diameter of the middle section of the liquid collecting section 112 is smaller than the inner diameter of the liquid discharging section 113. In one embodiment, the inner diameter of the liquid guiding section 111 may be equal to the inner diameter of the liquid discharging section 113.

[0057] In practical applications, to ensure that the liquid in the liquid guiding section 111 can smoothly enter the water inlet tank 124 and the liquid in the water outlet tank 125 can smoothly drain into the liquid collection section 112, a liquid inlet pipe 122 can be provided in the loading tank 121 at a position corresponding to the water inlet tank 124 (i.e., the liquid inlet pipe 122 is located in the outer cylinder 120), and a liquid drain pipe 123 can be provided in the loading tank 121 at a position corresponding to the water outlet tank 125 (i.e., the liquid drain pipe 123 is located in the outer cylinder 120); the inner cavity of the liquid guiding section 111 is connected to the water inlet tank 124 in sequence through the first inlet hole 114 and the liquid inlet pipe 122; the inner cavity of the liquid collection section 112 is connected to the water outlet tank 125 in sequence through the second inlet hole 115 and the liquid drain pipe 123.

[0058] Considering that the hollow drill pipe 110 is usually rotating during drilling, to ensure that the liquid in the fluid guiding section 111 can enter the inlet tank 124 and the liquid in the outlet tank 125 can enter the collection section 112 while the hollow drill pipe 110 is in its hollow state, thus continuously cooling the chip on the support plate 128, in one embodiment, a first inner sleeve 130-A and a second inner sleeve 130-B are provided inside the outer cylinder 120. The first inner sleeve 130-A is fitted outside the fluid guiding section 111, and the second inner sleeve 130-B is fitted outside the collection section 112. The first inner sleeve 130-A and the second inner sleeve 130-B are fixedly installed on the outer cylinder 120, and the hollow drill pipe 110 can rotate within the first inner sleeve 130-A and the second inner sleeve 130-B. In practical implementation, bearings 135 are connected to the inner walls of both ends of the first inner sleeve 130-A. The inner rings of both sets of bearings 135 are connected to the outer wall of the hollow drill rod 110, and the first inner sleeve 130-A is rotatably connected to the hollow drill rod 110 through the two sets of bearings 135. Similarly, bearings 135 are connected to the inner walls of both ends of the second inner sleeve 130-B. The inner rings of both sets of bearings 135 are connected to the outer wall of the hollow drill rod 110, and the second inner sleeve 130-B is rotatably connected to the hollow drill rod 110 through the two sets of bearings 135. This allows the hollow drill rod 110 to rotate within both the first inner sleeve 130-A and the second inner sleeve 130-B.

[0059] Furthermore, the inner wall of the first inner sleeve 130-A is provided with multiple sealing grooves 131, and a sealing ring 132 is provided between each sealing groove 131 and the outer wall of the liquid guiding section 111. Each sealing groove 131 is rotatably connected to its corresponding sealing ring 132, and each sealing ring 132 is fixedly connected to the outer wall of the liquid guiding section 111. The multiple sealing grooves 131 on the inner wall of the first inner sleeve 130-A include a first sealing groove and a second sealing groove, which are adjacent to each other. A first liquid storage tank 133-A is provided in the area between the first sealing groove and the second sealing groove on the inner wall of the first inner sleeve 130-A. The inner cavity of the liquid guiding section 111 is connected to the water inlet tank 124 in sequence through the first inlet hole 114, the first liquid storage tank 133-A, and the liquid inlet pipe 122. The sealing rings 132 in the first sealing groove and the second sealing groove can prevent the liquid in the first liquid storage tank 133-A from leaking out.

[0060] In specific implementation, multiple sealing grooves 131 can be opened at both ends of the inner wall of the first inner sleeve 130-A, and a first liquid storage tank 133-A can be opened in the middle area of ​​the inner wall of the first inner sleeve 130-A.

[0061] Similarly, the inner wall of the second inner sleeve 130-B is provided with a plurality of sealing grooves 131 (the structure of the second inner sleeve 130-B can also be referenced). Figure 8 Each sealing groove 131 is provided with a sealing ring 132 between itself and the outer wall of the liquid collection section 112. Each sealing groove 131 is rotatably connected to its corresponding sealing ring 132, and each sealing ring 132 is fixedly connected to the outer wall of the liquid collection section 112. The inner wall of the second inner sleeve 130-B has multiple sealing grooves 131, including a third sealing groove and a fourth sealing groove, which are adjacent to each other. A second liquid storage tank 133-B is formed in the area between the third and fourth sealing grooves on the inner wall of the second inner sleeve 130-B. The inner cavity of the liquid collection section 112 is connected to the water outlet tank 125 sequentially through the second inlet hole 115, the second liquid storage tank 133-B, and the drain pipe 123. The sealing rings 132 in the third and fourth sealing grooves prevent liquid leakage from the second liquid storage tank 133-B.

[0062] In specific implementation, multiple sealing grooves 131 can be opened at both ends of the inner wall of the second inner sleeve 130-B, and a second liquid storage tank 133-B can be opened in the middle area of ​​the inner wall of the second inner sleeve 130-B.

[0063] To ensure that the liquid in the liquid guiding section 111 can smoothly enter the water inlet tank 124, the cylinder wall of the first inner sleeve 130-A is also provided with a liquid inlet channel 134-A. The inner cavity of the liquid guiding section 111 is connected to the water inlet tank 124 in sequence through the first inlet hole 114, the first liquid storage tank 133-A, the liquid inlet channel 134-A and the liquid inlet pipe 122.

[0064] Similarly, in order to allow the liquid in the outlet tank 125 to be smoothly discharged into the collection section 112, the wall of the second inner sleeve 130-B is also provided with a drain channel 134-B. The inner cavity of the collection section 112 is connected to the outlet tank 125 in sequence through the second inlet hole 115, the second storage tank 133-B, the drain channel 134-B and the drain pipe 123.

[0065] To further reduce the resistance of liquid entering the inlet tank 124 from the liquid guiding section 111 and increase the speed at which liquid enters the inlet tank 124 from the liquid guiding section 111, the direction in which the first inlet hole 114 extends from the first end to the second end forms an acute angle with a first direction. The first end is the end of the first inlet hole 114 near the inner cavity of the liquid guiding section 111, and the second end is the end of the first inlet hole 114 near the first inner sleeve 130-A. The first direction is the wall thickness direction of the liquid guiding section 111 at the first end, and the wall thickness direction is the direction from the inner wall of the liquid guiding section 111 to the outer wall of the liquid guiding section 111. That is, the first inlet hole 114 is an oblique inlet hole with an inclined wall.

[0066] To increase the speed at which liquid flows from the outlet tank 125 into the collection section 112, the second inlet hole 115 extends in the same direction from the first end to the second end as the second direction. The first end is the end of the second inlet hole 115 near the inner cavity of the collection section 112, and the second end is the end of the second inlet hole 115 near the second inner sleeve 130-B. The second direction is the wall thickness direction of the collection section 112 at the first end, which is the direction from the inner wall of the collection section 112 to the outer wall of the collection section 112. That is, the second inlet hole 115 is a vertical inlet hole, resulting in a shorter drainage path.

[0067] In this embodiment of the application, the cooling plate includes a silicon steel sheet 126 and a cooling pipe 127 disposed on the silicon steel sheet 126. The liquid inlet of the cooling pipe 127 is connected to the water inlet tank 124, and the liquid outlet of the cooling pipe 127 is connected to the water outlet tank 125.

[0068] The silicon steel sheet 126 can be used to fix the cooling pipe 127. To improve stability, the cooling pipe 127 can be inserted into the inner wall of the silicon steel sheet 126. To increase the liquid flow rate in the cooling plate and improve the cooling effect, the cooling pipe 127 can be S-shaped.

[0069] In this embodiment, a chip corresponding to a drilling parameter sensor is mounted on the support plate 128. Specifically, the chip corresponding to the drilling parameter sensor may be mounted on the side of the support plate 128 opposite to the cooling plate. The chip corresponding to the drilling parameter sensor may include a control chip 150 and a memory chip 151. The control chip 150 may specifically be a main control chip. To increase storage capacity, there may be multiple memory chips 151, meaning multiple memory chips 151 may be disposed on the support plate 128, and all of these multiple memory chips 151 are electrically connected to the control chip 150.

[0070] Taking the control chip 150 as the main control chip as an example, in specific implementations, the main control chip can be a PIC18F6723, and the PCB circuit diagram of the main control chip can be as follows: Figure 10 As shown. The wireless transmission module in the main control chip can be a high-speed continuous wireless serial port module, which features point-to-point, high-speed continuous transmission, and full-duplex communication. It also has a frequency hopping algorithm to improve anti-interference capabilities and full-duplex continuous transmission. Combined with the product's hardware flow control, it can realize the rapid transmission of large amounts of data or files.

[0071] Multiple memory chips 151 are mounted on the carrier board 128. For example, one external FLASH chip and four NAND FLASH chips can be mounted on the carrier board 128. The external FLASH chip can be an AT45DB641E, with a capacity of 8Mb per chip, and can be used to store system information and other parameters. The NAND FLASH chips can be an MT29F32G08ABAAAWP-ITZ:A, with parallel data line transmission, and each chip has a storage capacity of 4Gb. Therefore, the four NAND FLASH chips have a total storage capacity of 16Gb, which can be used to store drilling parameters. The PCB circuit diagram of the four NAND FLASH chips can be shown below. Figure 11 As shown.

[0072] The main control chip integrates a main control module. The USB circuit within this module can utilize the FT245RL USB chip, employing a FIFO protocol for USB data conversion. Data transfer rates can reach 1Mb / s. Combined with NAND flash memory using a parallel data cable, this reduces microcontroller resource waste and redundant code. The PCB circuit diagram of the USB chip can be seen as follows: Figure 12 As shown.

[0073] In practical applications, the drilling parameter sensor can be mounted on the housing 160, and is electrically connected to the control chip 150 and the memory chip 151. Specifically, the drilling parameter sensor can be mounted on the outer wall of the housing 160. After acquiring drilling parameters, the drilling parameter sensor can store these parameters in the memory chip 151, and the control chip 150 can read and transmit these data to the surface.

[0074] The types and number of drilling parameter sensors can be selected according to actual needs. For example, drilling parameter sensors may include one or more of the following: rotational speed sensor 161, drilling pressure sensor 162, torque sensor 163, vibration sensor 164, temperature sensor 165, and air pressure sensor 166. The rotational speed sensor 161, drilling pressure sensor 162, torque sensor 163, vibration sensor 164, temperature sensor 165, and air pressure sensor 166 can respectively collect downhole drilling parameters—rotational speed, drilling pressure, torque, impact vibration, temperature, and inner and outer annular pressure.

[0075] When there are many drilling parameter sensors to be installed, in order to minimize the mutual interference between the sensors, the outer wall of the outer cylinder 120 can be provided with multiple loading slots 121. The internal structure of each loading slot and the corresponding structure of the hollow drill pipe 110 can be referred to the foregoing content, and will not be repeated here. Furthermore, each loading slot 121 is provided with a corresponding housing 160, and multiple drilling parameter sensors can be installed on multiple housings 160 according to actual needs.

[0076] When multiple loading slots 121 are provided on the outer wall of the outer cylinder 120, taking three loading slots 121 as an example, the three loading slots 121 can be arranged in an equilateral triangle along the circumference of the hollow drill rod 110. To allow the liquid in the liquid guiding section 111 to enter the water inlet tank 124 in the three loading slots 121, three liquid inlet pipes 122 can be provided, each corresponding to one of the three loading slots 121. Correspondingly, three liquid inlet channels 134-A can be provided on the inner wall of the first inner sleeve 130-A, each corresponding to one of the three liquid inlet pipes 122. After the liquid in the liquid guiding section 111 enters the first storage tank 133-A through the first inlet hole 114, it then enters the water inlet tank 124 in the three loading slots 121 through the three liquid inlet channels 134-A and the three liquid inlet pipes 122, respectively.

[0077] Similarly, to allow the liquid in the outlet tanks 125 of the three loading tanks 121 to drain into the collection section 112, three drainage pipes 123 can be installed, each corresponding to one of the three loading tanks 121. Correspondingly, three drainage channels 134-B can be formed on the inner wall of the second inner sleeve 130-B, each corresponding to one of the three drainage pipes 123. The liquid in the outlet tanks 125 of the three loading tanks 121 flows through the three drainage pipes 123 and the three drainage channels 134-B into the second storage tank 133-B, and then drains into the collection section 112 through the second inlet hole 115.

[0078] In this embodiment, by providing a housing 160 on the side of the support plate 128 opposite to the cooling plate, the chip on the support plate 128 can be protected from excessive pressure. To further improve the protective effect and reduce the pressure on the chip, the housing 160 is preferably an arc-shaped housing.

[0079] In this embodiment of the application, both ends of the hollow drill rod 110 are exposed to the outer cylinder 120. The two ends of the hollow drill rod 110 exposed to the outer cylinder 120 can also be respectively fitted with outer sleeves 140. Each outer sleeve 140 is fixedly connected to the outer cylinder 120, and each outer sleeve 140 is rotatably connected to the hollow drill rod 110 through a bearing 135.

[0080] Furthermore, each outer sleeve 140 has a mating sleeve 170 at the end away from the outer cylinder 120, and the outer sleeve 140 and the mating sleeve 170 are rotatably connected by a bearing. The end of each mating sleeve 170 away from the outer sleeve 140 is rotatably connected to a hollow flower key 180, and the inner wall of the inner cavity of each hollow flower key 180 is sealed and fixedly connected to the inner wall of the hollow drill rod 110.

[0081] Both the drill collar 200 and the drill string 300 have floral keyways 230 on their end walls near the monitoring component 100, with each hollow floral key 180 engaging with its corresponding floral keyway 230. The hollow drill rod 110 is fixedly connected to the drill collar 200 and the drill string 300 through the engagement of the hollow floral key 230 and the floral keyway 230. The drill collar 200 has a liquid outlet channel 210, which communicates with the hollow floral key 180 and the hollow drill rod 110. After liquid is injected into the drill string 300, the liquid flows through the drill string 300 into the hollow drill rod 110, then from the hollow drill rod 110 into the drill collar 200 and is discharged through the liquid outlet channel 210 of the drill collar 200.

[0082] In addition, the end of the drill collar 200 away from the monitoring component 100 is rotatably connected to the drill bit 220, and there can be multiple drill bits, for example, there can be three sets of drill bits.

[0083] The working principle of the drilling equipment provided in this application embodiment is as follows:

[0084] During drilling, the drill string 300 is driven to rotate, and the hollow drill pipe 110 and drill collar 200 are driven to rotate through the cooperation of the hollow spline key 180 and the spline keyway 230. When the drill bit 220 on the drill collar 200 drills into the formation to a certain depth, the control chip 150 and memory chip 151 will work in a high temperature and high pressure environment. At this time, drilling fluid and coolant (hereinafter referred to as liquids) can be injected into the drill string 300. The drilling fluid can be used to remove the waste cuttings generated during the drilling process, and the coolant can be used to cool the control chip 150, memory chip 151 and drill bit. The liquid will flow into the hollow drill pipe 110 through the drill string 300. Because the inner diameter of the liquid guiding section 111 is larger than that of the liquid collecting section 112, and the inner diameter of the liquid outlet section 113 is also larger than that of the liquid collecting section 112, the flow velocity of the liquid in the liquid guiding section 111 is less than that in the liquid collecting section 112. Based on the principle that the faster the flow velocity, the lower the pressure, the pressure in the liquid collecting section 112 is less than that in the liquid guiding section 111. Therefore, when the liquid flows in the liquid guiding section 111, it flows into the first liquid storage tank 133-A through the first inlet hole 114, then further into the liquid inlet channel 134-A, and then into the water inlet tank 124 through the liquid inlet pipe 122. Under the action of the pressure difference between the liquid collecting section 112 and the liquid guiding section 111, a hydraulic pressure difference will be generated between the water inlet tank 124 and the water outlet tank 125. Based on Bernoulli's principle, the liquid in the water inlet tank 124 will flow into the water outlet tank 125 through the cooling plate, thereby cooling the chip on the carrier plate 128. Then, the liquid in the water tank 125 will flow into the second storage tank 133-B through the drain pipe 123 and the drain hole 134-B, and then flow into the inner cavity of the liquid collection section 112 through the second inlet hole 115 to continue to be delivered to the drill bit.

[0085] Based on the above principle, the chip on the carrier plate 128 can be cooled down, and the housing 160 can prevent the chip from being subjected to excessive pressure, thereby improving the rate of drilling parameter acquisition and reading under high temperature and high pressure environment, and thus the drilling parameters can be transmitted to the ground in a timely manner.

[0086] It is understood that the drilling equipment provided in the above embodiments of this application includes a monitoring component 100, a drill collar 200, and a drill string 300. One end of the monitoring component 100 is connected to the drill collar 200, and the other end of the monitoring component 100 is connected to the drill string 300. The monitoring component 100 includes a hollow drill pipe 110 and an outer cylinder 120 sleeved on the outside of the hollow drill pipe 110. The hollow drill pipe 110 flows along the liquid flow... The moving direction is divided into a liquid guiding section 111, a liquid collecting section 112, and a liquid discharging section 113. The inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid guiding section 111, and the inner diameter of the liquid collecting section 112 is smaller than the inner diameter of the liquid discharging section 113. A first inlet hole 114 is opened on the rod wall of the hollow drill rod 110 corresponding to the liquid guiding section 111, and a second inlet hole 115 is opened on the rod wall of the hollow drill rod 110 corresponding to the liquid collecting section 112. The outer wall of the outer cylinder 120 is provided with an insertion groove 121. A water inlet tank 124 is provided at one end of the insertion groove 121 near the drill string 300, and a water outlet tank 125 is provided at one end of the insertion groove 121 near the drill collar 200. The inner cavity of the liquid guiding section 111 is connected to the water inlet tank 124 through the first inlet hole 114, and the inner cavity of the liquid collecting section 112 is connected to the water outlet tank 125 through the second inlet hole 115. A cooling plate is provided between the water inlet tank 124 and the water outlet tank 125. The liquid inlet of the cooling plate is connected to the water inlet tank 124, and the liquid outlet of the cooling plate is connected to the water outlet tank 125. A support plate 128 is provided on the side of the cooling plate away from the insertion groove 121. A chip corresponding to the drilling parameter sensor is installed on the support plate 128. A housing 160 is provided on the side of the support plate 128 away from the cooling plate. Based on the drilling equipment provided in this application embodiment, by cooling the chip corresponding to the drilling parameter sensor and reducing the pressure on the chip, data can be quickly acquired and read under high temperature and high pressure environment. As a result, ground personnel can obtain real-time drilling parameters in a timely manner and adjust the construction plan accordingly.

[0087] Furthermore, in existing technologies, the capacity used to store drilling parameters is relatively small, typically only 8M bytes. However, based on the solution provided in the above embodiments of this application, large-capacity storage can be achieved by setting up multiple large-capacity memories. Moreover, by connecting the microcontroller, memory chip, and USB chip together via a data cable, reading and sending can be performed simultaneously, achieving a storage time of only 350µs for 8K bytes. In addition, by using a FIFO parallel port data line, fast data reading can be achieved.
