Description

Technical Field

[0001] This invention relates to the field of petroleum equipment technology, and more specifically to a method for identification and quality inspection of drilling tools at well sites. Background Technology

[0002] In production operations, the management of equipment and tools is crucial for both production efficiency and quality. To improve efficiency and reduce costs, identification technology can be used to manage equipment and tools during production. Specifically, the following identification technologies can be employed: 1. Barcode technology: Barcodes are affixed to equipment and tools, and their usage and location information are recorded by scanning the barcodes. This technology is simple, easy to implement, and low in cost, but the barcode information needs to be updated regularly.

[0003] 2. Radio Frequency Identification (RFID): This technology involves attaching RFID tags to equipment and tools, and using RFID readers to record the usage and location information of the equipment and tools. This technology enables long-distance, automated identification and tracking, but the durability and interference resistance of the RFID tags need to be considered.

[0004] 3. Smart Card Technology: Information about equipment and tools is written into smart cards, and their usage and location information are recorded using a smart card reader. This technology offers high security and accuracy, but the cost and ease of use of smart cards need to be considered.

[0005] The adoption of identity verification technology can improve the efficiency and accuracy of equipment and tool management, reduce production costs, and improve product quality. At the same time, the security and privacy protection of identity verification technology need to be considered to prevent data leakage and misuse.

[0006] In certain specific application environments, the confidentiality of equipment and tools is crucial, and these equipment and tools often face extreme operating conditions, including high temperatures, high pressures, and strong corrosion. In such cases, exposed methods such as nameplates, barcodes, and QR codes pose a risk of information leakage. Furthermore, RFID and smart cards, due to their electronic components, are at risk of failure in extreme environments. Additionally, the currently researched specialized RFID tags have high manufacturing costs, hindering their widespread application.

[0007] Chinese invention patent document CN202362274U, published on August 1, 2012, discloses a wellhead ultrasonic testing device for drilling tools. The drilling tool is installed in the central hole of a rotary table. The ultrasonic testing device includes a connector, an ultrasonic water jacket, and an ultrasonic probe. The connector is fitted into the central hole of the rotary table and has a water pipe and signal line channel running from top to bottom. The lower end of the water pipe of the connector is connected to the water pipe connector of the ultrasonic water jacket, and the upper end of the ultrasonic water jacket is connected to the lower end of the connector. The ultrasonic probe is located inside the ultrasonic water jacket, and the signal output line of the ultrasonic probe is placed in the signal line channel. This invention is simple and quick to install and remove, and compared with detection devices such as magnetic leakage and eddy current detectors, it is easier to detect various defects in drilling tools.

[0008] However, the above technical solutions can only detect defects in the drilling tools, but cannot bind the structural information of the drilling tools to the drilling tools, thus failing to identify and track the drilling tools and hindering the management and control of well site equipment. Summary of the Invention

[0009] To overcome the defects and shortcomings of the existing technologies, this invention provides a method for identification and quality inspection of drilling tools at well sites. The method utilizes acoustically conductive materials to create the tags and employs ultrasonic imaging for tag identification, expanding the application scope, distinguishing information from various drilling tools, improving tag identification efficiency, and making the identification process more convenient and flexible. By using ultrasonic identification, defects can be monitored while identifying different drilling tools, improving the quality and efficiency of well site drilling tool management. This addresses the risk of failure in extreme environments associated with RFID and smart cards due to the presence of electronic components, and also solves the problem of high manufacturing costs for currently researched special RFID tags, which hinders their widespread application.

[0010] To address the problems existing in the prior art, the present invention is achieved through the following technical solution: A method for identification and quality inspection of drilling tools at well sites includes the following steps: S1. An ultrasonic generator and collector is installed at the wellhead, and identification tags are installed on each joint of the drill string. The drill string is then lowered into the well. The identification tags are made of sound-conducting material and have grooves inside. The top of the tag with grooves forms an ultrasonic thickness measurement interface one, and the bottom of the structural block without grooves forms an ultrasonic thickness measurement interface two. Interface one is used to reflect Y-type acoustic wave data to the ultrasonic generator and collector, and interface two is used to reflect X-type acoustic wave data to the ultrasonic generator and collector. S2. When the drill string connector is lowered into the ultrasonic generator and collector, the label on the connector is scanned, and ultrasonic imaging technology is used to identify the label's identity information; specifically including: S21. Use an ultrasonic generator and collector to scan the top surface of the label. When the first interface inside the label is scanned, Y-type acoustic wave data is obtained. When the second interface inside the label is scanned, X-type acoustic wave data is obtained. S22. Based on the X-type sound wave data and Y-type sound wave data in S1, and combined with the sound velocity, obtain the distance data from the top surface of the label to interface two and the distance data from the top surface of the label to interface one. S23. Round the two distance data obtained in S22 to obtain the rounded distance data. S24. Denoise the rounded distance data to obtain distance data with only two values; S25. Define the points on the top surface of the label corresponding to the two values ​​as two different colors on the Cartesian coordinate system to obtain the identity code graphic. After optimizing the graphic, display it on the background software. S26. Recognize the identity code graphic obtained in S25 to obtain the tag's identity information.

[0011] S3. When the drill rod is lowered into the ultrasonic generator and collector, ultrasonic monitoring technology is used to monitor defects in the rod and obtain information data about the rod. S4. The drill string contains multiple joints and corresponding rods. During the drilling process, repeat steps S2-S3 to obtain the information data of the n joints and the n rods corresponding to the n joints before the operation. S5. When the drill string is pulled out, the last rod first goes into the ultrasonic generator and collector for defect monitoring, and then the corresponding joint goes into the ultrasonic generator and collector for identification. After the drill string is completely pulled out, the identities of the n joints after the operation and the information data of the n rods corresponding to the n joints are obtained. S6. Update the rod information data corresponding to the identity of each joint after drilling.

[0012] In S1, X-type acoustic data refers to the time difference between the ultrasonic wave emitted from the top surface of the label and the second interface and its subsequent recovery, while Y-type acoustic data refers to the time difference between the ultrasonic wave emitted from the top surface of the label and the first interface and its subsequent recovery.

[0013] In step S22, the distance data from the top surface of the label to interface two and the distance data from the top surface of the label to interface one are calculated according to the following formula: Formula 1 In Equation 1, S is the distance data from the top surface of the label to interface two or the distance data from the top surface of the label to interface one, V is the speed at which the sound wave propagates in the material of the label, and T is the time difference between the emission and recovery of the sound wave at that point.

[0014] In step S23, the rounding process refers to rounding the integer part of the vertical distance data from each point on the top surface of the label to the interface inside the label.

[0015] In step S24, denoising the rounded distance data includes: S241. Map the rounded distance data to the points corresponding to the top surface of the label on a Cartesian coordinate system. S242. If a point's data is different from the data of its four adjacent points (up, down, left, and right), it is defined as noisy data; the adjacent data is selected to replace the data of that point.

[0016] In step S25, optimizing the graphic refers to smoothing the graphic using an algorithm.

[0017] In S3, using ultrasonic monitoring technology to monitor defects in the rod and obtain information data about the rod means scanning the rod with an ultrasonic generator and collector to obtain data on the inner and outer surfaces and radial direction of the rod and to determine whether fatigue cracks or damage exist.

[0018] In step S3, the defect monitoring of the rod using ultrasonic monitoring technology specifically includes: scanning the rod using an ultrasonic generator and collector to obtain data on the inner and outer surfaces and radial direction of the rod and to determine whether fatigue crack damage exists.

[0019] In S1, the drilling speed of the drill string is 0.2-0.5 m / s.

[0020] The ultrasonic wave generating and collecting device is a ring probe.

[0021] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1. This invention employs ultrasonic imaging for tag identification, distinguishing information about various drilling tools. This reduces system complexity while improving tag identification efficiency and the ability to control drilling tools in the well site. Using ultrasonic identification, defects can be monitored simultaneously with the identification of different drilling tools, improving the quality and efficiency of well site drilling tool management. It also enables timely acquisition of the location and internal information of drilling tools, improving well site drilling tool maintenance efficiency. Furthermore, ultrasonic imaging technology provides higher identification accuracy and resolution, capable of detecting smaller and finer features, making ultrasonic imaging tags superior in scenarios requiring precise identification. Moreover, ultrasonic imaging tags do not require an external excitation source; identification can be achieved using only an ultrasonic transmitter and receiver, making it more convenient and flexible. In contrast, some magnetic identification systems may require an external magnetic field excitation source, increasing system complexity and cost. Attached Figure Description
