[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the present invention adopts passive 900M radio frequency identification (RFID) technology, which is an automatic identification technology that exchanges energy through electromagnetic fields. Compared with traditional active RFID, passive 900M RFID does not require built-in batteries, so it has better anti-interference performance and long service life, and is suitable for harsh environments such as underground.

[0028] In the downhole drill pipe counting, the main advantages of passive 900M RFID technology are reflected in the following aspects: 1. Long communication distance: Passive 900M RFID technology uses the reflection and penetration characteristics of electromagnetic waves to achieve long-distance signal transmission, thereby realizing the identification and counting of long-distance drill pipes. 2. Good anti-collision performance: Because passive 900M RFID has high signal sensitivity, it can effectively detect and avoid other interference signals, thereby reducing misidentification and conflicts when multiple devices are working at the same time.

[0029] The embodiment of the present invention provides a drill rod identification and counting method based on RFID technology. The drill rod is equipped with an RFID chip. In addition, an RFID card reader is deployed in the middle of the drill rod stroke at the drilling rig to ensure that the card reader can detect the wireless signal of the drill rod equipped with the RFID chip. Figure 1A schematic flow chart of a drill rod identification and counting method based on RFID technology is shown, and the method comprises the following steps:

[0030] S110, obtaining tag information of the drill pipe based on RFID technology.

[0031] S120: Update drilling label queue information according to the label information.

[0032] Optionally, new label information is added to the drilling label queue or erroneous label information is corrected according to the label information, so as to update the drilling label queue information.

[0033] S130, counting the number of tags in the drilling tag queue information to perform drilling counting.

[0034] S140: Update the drilling exit label queue information according to the label information and the drilling entry label queue after the drilling is completed.

[0035] Optionally, new label information is added to the drill return label queue or wrong label information is corrected according to the label information and the drill return label queue after the drill return is completed, so as to update the drill return label queue information.

[0036] S150, counting the number of labels in the drill withdrawal label queue information to perform drill withdrawal counting.

[0037] The embodiment of the present invention provides a drill rod identification and counting method based on RFID technology, which obtains the label information of the drill rod based on RFID technology; updates the drilling label queue information according to the above label information, so that the drilling label queue information can timely and correctly reflect the drilling information of the drill rod, thereby ensuring the timeliness and accuracy of the subsequent drilling count; counts the number of labels in the above drilling label queue information for drilling count; updates the drill withdrawal label queue information according to the above label information and the drilling label queue after the drilling is completed, so that the drill withdrawal label queue information can timely and correctly reflect the drill withdrawal information of the drill rod, thereby ensuring the timeliness and accuracy of the subsequent drill withdrawal count; counts the number of labels in the above drill withdrawal label queue information for rod withdrawal count. The label information of the drill rod is obtained based on RFID technology, and the intelligent counting of the drill rod is realized by continuously updating the drilling label queue and the drill withdrawal label queue and counting the number of labels therein. In addition, the reliability of the intelligent counting of the drill rod is improved by correctly identifying and accurately counting the drill rod.

[0038] Optionally, as a specific implementation, see Figure 2 A schematic flow chart of a drilling rod identification and counting method shown in FIG. Figure 3 A schematic flow chart of drill rod identification and counting is shown.

[0039] The step S120 includes: if the label information is different from the last label information in the drilling label queue, adding the label information to the drilling label queue as the new last label information of the drilling label queue.

[0040] It should be noted that if the tag information is the same as the last tag information of the drilling tag queue, the tag information continues to be identified, and the last tag information of the drilling tag queue is obtained, indicating that the drilling rig in the drilling field is in the drilling state at this time.

[0041] The above-mentioned step S140 includes: if the above-mentioned label information is the same as the penultimate label information of the drilling label queue after the drilling is completed, then the penultimate label information of the drilling label queue after the drilling is completed is deleted, and the deleted penultimate label information of the drilling label queue after the drilling is completed is added to the drill withdrawal label queue as the new end label information of the drill withdrawal label queue.

[0042] It should be noted that if the label information is different from the penultimate label information of the drilling label queue after the drilling is completed, the label information continues to be identified, and the penultimate label information of the drilling label queue after the drilling is completed and the penultimate label information of the drilling back label queue are obtained, indicating that the drilling rig in the drilling field is in the drilling back state at this time.

[0043] Alternatively, as another specific implementation, see Figure 4 Another schematic flow chart of drilling rod identification and counting shown in FIG. Figure 5 Another schematic flow chart of drill rod identification and counting during drill withdrawal is shown.

[0044] The above-mentioned step S120 includes: if the above-mentioned label information is different from the penultimate label information of the drilling label queue, then judging whether the above-mentioned label information is the same as the penultimate label information of the drilling label queue; if the above-mentioned label information is the same as the penultimate label information of the drilling label queue, then deleting the penultimate label information of the drilling label queue; if the above-mentioned label information is different from the penultimate label information of the drilling label queue, then adding the above-mentioned label information to the drilling label queue as the new end label information of the drilling label queue. In this way, by judging whether the above-mentioned label information is the same as the penultimate label information of the drilling label queue, it is possible to timely and accurately identify whether there is a drilling abnormality, so that the drilling site staff can deal with the above-mentioned abnormal situation in time.

[0045] It should be noted that if the label information is the same as the penultimate label information of the above-mentioned drilling label queue, the label information continues to be identified, and the penultimate label information of the drilling label queue and the penultimate label information of the drilling label queue are obtained, indicating that the drilling rig in the drilling field is in the drilling state at this time.

[0046] The above-mentioned step S140 includes: if the above-mentioned label information is the same as the last label information of the drilling label queue after the drilling is completed, the last label information of the drilling label queue after the drilling is completed is deleted, and the last label information of the drilling label queue after the drilling is completed is added to the drill back label queue as the new end label information of the drill back label queue; if the above-mentioned label information is different from the last label information of the drilling label queue after the drilling is completed, it is determined whether the above-mentioned label information is the same as the last label information of the drill back label queue; if the above-mentioned label information is different from the last label information of the drill back label queue, the last label information last deleted in the drilling label queue after the drilling is completed is restored to the end of the drilling label queue after the drilling is completed, and the last label information of the drill back label queue is deleted. In this way, by determining whether the above-mentioned label information is the same as the last label information of the second drill back label queue, it is possible to timely and accurately identify whether there is a drill back abnormality, so that the drilling site staff can deal with the above-mentioned abnormality in a timely manner.

[0047] It should be noted that if the label information is the same as the penultimate label information of the above-mentioned drill withdrawal label queue, the label information will continue to be identified, and the penultimate label information of the drilling label queue and the penultimate label information of the drill withdrawal queue after drilling is completed will be obtained, indicating that the drilling rig in the drilling field is in the drill withdrawal state at this time.

[0048] The embodiment of the present invention provides a method for handling an abnormal situation. As for other abnormal situations, they can be handled with reference to the above specific implementation methods.

[0049] Optionally, continue to see Figure 2-5 The above method also includes: before the drilling of the drill rod is completed, continuously obtaining label information and drilling label queue information; before the drilling of the drill rod is completed, continuously obtaining label information, drilling label queue information after drilling is completed, and drilling label queue information.

[0050] Optionally, the method further includes: after the drilling of the drill rod is completed, sending a drilling completion message to the monitoring system; after the drilling of the drill rod is completed, sending a drilling withdrawal completion message to the monitoring system.

[0051] It should be noted that, according to the drilling completion message received by the monitoring system, an instruction to end drilling or an instruction to start drilling back can be issued; according to the drilling completion message received by the monitoring system, an instruction to end drilling back can be issued. Among them, whether the drilling operation of the drill rod and the drilling operation of the drill rod are completed can be judged by human participation.

[0052] The embodiment of the present invention provides a specific drill rod identification and counting method based on RFID technology, comprising the following steps:

[0053] 1. Hardware equipment construction: Deploy the RFID reader antenna in the middle of the drill rod stroke at the drilling rig to ensure that the reader can detect the wireless signal of the drill rod equipped with a special anti-metal tag;

[0054] 2. Software algorithm design: According to the characteristics of passive 900M RFID technology, the corresponding recognition algorithm is designed to analyze the received wireless signal of the drill rod to obtain the forward or backward status of the drill rod;

[0055] 3. Data collection and analysis: During the operation of the drilling rig, the RFID signals are collected in real time, and the number of drill rods is identified through analysis algorithms;

[0056] 4. Result output and display: The analysis results are presented on the monitoring system in the form of charts or text, so that operators can check the status of the drill pipe;

[0057] 5. Optimization and adjustment: According to the actual application effect, the position, quantity and performance parameters of the RFID reader are optimized and adjusted to further improve the accuracy and efficiency of downhole drill pipe counting.

[0058] The above step 1 includes: firstly, drilling a circular hole with a diameter of 14 mm and a depth of 3.5 mm on the drill rod (different labels require different hole diameters) for placing the ceramic label, and then pouring high temperature and wear-resistant structural adhesive to install and fix the label.

[0059] It should be noted that the drilling rig model used in the embodiment of the present invention is 4500, and the drill rod diameter is 73mm. The rated speed is 75r / min, that is, 1.25r / s. The drilling speed of the tag applied to the drill rod is 3.43m / s. Since the recognition distance of the anti-metal tag is relatively short (10-20CM) and the recognition angle is relatively small, the card reader is required to have a relatively high reading speed. In order to prevent the tag from being squeezed and damaged during the drill rod operation, the tag needs to be buried in the round hole, which causes the wireless signal to deteriorate. Therefore, the power of the card reader is required to be relatively large. After testing, the card reader with a power of more than 30dB has a better effect.

[0060] See also Figure 6 A schematic flow chart of drill rod identification and counting is shown. When performing RFID tag identification, the embodiment of the present invention adopts two queues. One queue is the RFID tag queue during the drilling process. This queue stores the queue of drill rods currently installed on the drilling rig, which is called the drilling tag queue. The other queue is the queue of drill rods after the drill rods are removed from the drilling rig after the drilling is withdrawn, which is called the withdrawn drill tag queue.

[0061] The above step 3 includes: starting the drilling operation, identifying the RFID tag, and when the read RFID tag is different from the end information of the drilling tag queue, comparing it with the second-to-last tag. If the read tag information is the same as the second-to-last tag, the last tag information at the end of the drilling tag queue is deleted, indicating that an abnormality occurred during the drilling process, and it is necessary to exit the previous drilling and start drilling again; if the read RFID tag is different from the second-to-last tag, a new tag information is added to the end of the drilling tag queue. Determine whether it can be started through manual participation. If not, continue the drilling count; if so, start the de-drilling operation. Start the de-drilling operation, identify the RFID tag, and determine whether the read tag information is the same as the tag information at the end of the drilling tag queue. If the read tag information is different from the tag information at the end of the drilling tag queue, it is necessary to determine whether the read tag information is consistent with the tag at the end of the drill withdrawal tag list. If the read tag information is consistent with the tag at the end of the drill withdrawal tag list, it means that the drill rod is being withdrawn. If the read tag information is inconsistent with the tag at the end of the drill withdrawal tag list, it means that an abnormality has occurred in the drill withdrawal process and the drill needs to be withdrawn again. At this time, the deleted tag information needs to be restored to the drilling tag queue; if the read tag information is the same as the tag information at the end of the drilling tag queue, the drilling tag queue deletes the tag information at the end and adds this information to the drill withdrawal tag queue.

[0062] The embodiment of the present invention uses two RFID tag queues to effectively avoid the situation where drilling and retracting are required due to special circumstances during drilling operations. Conventional AI video analysis methods cannot effectively identify the occurrence of such a situation, resulting in repeated counting or omissions. A specific drill rod identification and counting method based on RFID technology provided in an embodiment of the present invention can effectively avoid such a situation.
