Description

Technical Field

[0001] This utility model belongs to the field of drilling tool testing technology, specifically relating to an automatic drilling tool length measuring device. Background Technology

[0002] During the construction of onshore oilfield drilling platforms, a wide variety of drill string specifications are involved, requiring length measurements of these varying lengths to confirm specifications and advance subsequent platform construction. However, each drill string is not only large and heavy but also comes in diverse lengths, and the complex working environment makes manual length measurement extremely tedious. Current manual measurement methods have many drawbacks: low automation, high labor intensity leading to low efficiency, and a high risk of errors, as well as posing certain safety hazards. Therefore, there is an urgent need for intelligent equipment to automate drill string length measurement, thereby improving the construction efficiency of oilfield drilling platforms.

[0003] Chinese patent document CN222938459U discloses a rapid drilling tool length measurement device. A magnetic plate on the side wall of a movable plate allows the plate to be magnetically attached to one end of the drilling tool. An elastic clamp secures a connecting platform and an infrared rangefinder to the end of the drilling tool away from the movable plate. The infrared rangefinder emits infrared light, which shines onto a reflective plate, which then reflects the infrared light back onto the rangefinder, enabling rapid and accurate measurement of the drilling tool length. However, this device requires moving the magnetic plate, resulting in low automation, and it cannot perform inkjet printing on the drilling tool during measurement. Utility Model Content

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1: like Figures 1-3 As shown, an automatic drill bit length measuring device includes a mounting bracket 1, a drive unit, a mounting plate 5, an inkjet printer 6, a slide table 7, a controller 8, and a measuring device 11. The mounting bracket 1 is connected to the mounting plate 5, and the slide table 7 is connected to the mounting plate 5 via the drive unit. The controller 8 is connected to the mounting bracket 1, and the measuring device 11 and the inkjet printer 6 are connected to the slide table 7. The controller 8 is electrically connected to the drive unit, the inkjet printer 6, and the measuring device 11.

[0020] Specifically, the mounting bracket 1 facilitates the installation of the automatic drill string length measuring device on the drill string inspection system. The controller 8 controls the drive unit to drive the slide 7 to move. The slide 7 drives the measuring device 11 and the inkjet printer 6 to move. The measuring device 11 measures the drill string and sends the measurement information to the controller 8, completing the automatic measurement of the drill string length. The inkjet printer 6 performs and completes the inkjet printing on the drill string, thereby confirming the drill string specifications. This can meet the needs of automatic measurement of drill string length during the construction of oilfield drilling platforms, effectively improve the efficiency of platform construction, and enhance operational safety. It has a positive promoting significance for the intelligent construction of oilfield drilling.

[0021] Example 2: Based on Embodiment 1, the drive unit includes a driver 2 and a lead screw 4, with the power output end of the driver 2 connected to the slide table 7 via the lead screw 4.

[0022] Specifically, the driver 2 drives the slide table 7 to move by rotating the lead screw 4, which has high transmission accuracy, high efficiency and smooth operation.

[0023] Preferably, the drive unit further includes a slide rail 9, which is connected to the mounting plate 5, and a slide table 7 is connected to the slide rail 9.

[0024] Specifically, the slide rail 9 reduces the friction when the slide table 7 moves and limits the slide table 7, so that the slide table 7 moves along the slide rail 9 with good stability.

[0025] Preferably, the slide rail 9 is a double-track slide rail.

[0026] Specifically, a double-track slide rail is used to ensure that the slide table 7 runs more smoothly and to prevent the slide table 7 from tipping over during operation.

[0027] Preferably, the slide rail 9 is a linear slide rail.

[0028] Specifically, the linear guide rail can better complete the measurement of the drill bit by the measuring instrument 11.

[0029] Preferably, the drive unit further includes a coupling 3, and the power output end of the driver 2 is connected to the lead screw 4 through the coupling 3.

[0030] Specifically, the power output end of the driver 2 drives the lead screw 4 to rotate through the coupling 3, thereby causing the slide table 7, which is fixed to the nut of the lead screw 4, to move linearly on the slide rail 9, which can efficiently transmit power and ensure the smoothness of transmission.

[0031] Preferably, the lead screw 4 is located between the two tracks of the double-track slide rail.

[0032] Specifically, this structure improves the stability of the entire device during operation.

[0033] Preferably, the measuring device 11 is a photoelectric switch.

[0034] Specifically, the photoelectric switch 11 achieves signal feedback through light reflection. When the drill bit 12 moves in a straight line, it will block the light signal of the photoelectric switch 11. At this time, the drill bit 12 can be detected, and the drill bit 12 will stop moving. The length can be calculated from the distance the drill bit 12 moves in a straight line.

[0035] Preferably, a proximity switch 10 is connected to the mounting plate 5 at the location of the driver 2.

[0036] Specifically, the proximity switch 10 is used to protect the travel distance during the movement of the slide table 7.

[0037] Preferably, the automatic drill string length measuring device is installed on the drill string detection system.

[0038] Specifically, the automatic drill string length measuring device is installed on the drill string inspection system, which is set up at the onshore oilfield drilling site. It is mainly used for automatic drill string loading and unloading from the catwalk, length measurement and statistics, thread cleaning, magnetic flux leakage detection, and inkjet coding. The main functions of this invention are to automatically measure drill string length, determine drill string model, and perform inkjet coding.

[0039] The working principle of this utility model is as follows: When the automatic drill string length measuring device is in operation, the driver 2 starts, driving the lead screw 4 to rotate via the coupling 3. This causes the slide 7, which is fixed to the nut of the lead screw 4, to move linearly on the slide rail 9. The photoelectric switch 11 provides signal feedback through light reflection. When the photoelectric switch 11 moves forward and aligns with one end of the drill string 12, it blocks the light signal of the photoelectric switch 11, and the mechanism records the initial time. When the photoelectric switch 11 continues to move forward to the other end of the drill string, it blocks the light signal of the photoelectric switch 11, and the mechanism records the end time. Based on the time difference between the two ends of the drill string 12 and the linear motion speed of the photoelectric switch 11 (i.e., the speed of the slide 7), the length of the drill string 12 is calculated. After the length measurement is completed, the slide 7 moves in the opposite direction, and the inkjet printer 6 moves in the opposite direction to perform an inkjet printing operation at a designated position on the drill string 12, marking the measured length model on the drill string 12, thereby determining the length model of the drill string 12. The proximity switch 10 is used to protect the slide 7 during its movement.

[0040] This utility model's automatic drill string length measuring device is fixed to the detection system via a mounting bracket 1. A linear module consisting of a ball screw (screw 4), slide rail 9 (drive unit 2), and slide table 7 is used to precisely move the photoelectric sensor (measuring device 11) at the measuring end. The repeatability of the photoelectric sensor at the measuring end is no less than 0.1mm. The main function of the inkjet printer 6 is to spray the well entry number onto the drill string 12 body as required and record the detection information of the drill string 12 into the database according to the number, facilitating traceability and querying of problematic drill strings. This achieves automatic measurement and classification of drill string length, improving the construction efficiency of oilfield drilling platforms. It can meet the needs of drill string length confirmation and classification during oilfield drilling platform construction, achieving fully automated operation, significantly improving work efficiency, and effectively solving the safety problems caused by manual measurement.
