Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic well logging, and more particularly to an intelligent speed regulation automatic control device for a hydraulic well logging drawworks drum. Background Art

[0002] During logging operations, the drum's speed control device is primarily composed of hydraulic actuators, sensors, and controllers. The drum is driven by a hydraulic actuator, but the speed of the drive needs to be monitored by sensors, and the monitored data is transmitted to the controller. Ultimately, the controller controls the hydraulic actuator to adjust the speed, driving the drum to release the cable. The cable release requires a tension sensor, such as a three-pulley tension sensor, which continuously monitors tension changes, adjusts the speed, and reduces friction between the cable and the well wall.

[0003] However, during long-term use, the surface of the cable cannot be guaranteed to remain clean. Impurities will adhere to the surface of many cables, forming bumps. When these bumps enter the three-pulley tension sensor, they will squeeze the three-pulley tension sensor, resulting in inaccurate detection data. In addition, some cable surfaces will show some wear and small depressions during long-term use, and these small depressions will hide some impurities. Impurities will interfere with the friction between the cable and the three-pulley tension sensor, thereby affecting the actual detection data.

[0004] In actual logging operations, impurities and wear on the cable surface not only reduce the accuracy of logging data, but also lead to the risk of cable jamming or breakage during the release process. Especially in complex downhole environments, the surface condition of the cable is crucial to the safety and reliability of logging operations. Therefore, an intelligent speed regulation and automation control device for the hydraulic logging winch drum is proposed. Summary of the Invention

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0022] like Figures 1 to 11 As shown, an intelligent speed regulation automatic control device for a hydraulic logging drawworks drum according to an embodiment of the present invention includes an intelligent controller 2, a hydraulic driver 3, a tension sensor 5, and a drum 4. During the logging process, the intelligent controller 2 controls the hydraulic driver 3 to drive the drum 4 to release the cable connected to the logging tool, and the cable passes through the tension sensor 5. During the logging operation, the entire device is centered around the intelligent controller 2, which receives and processes signals from the tension sensor 5 in real time. The tension sensor 5 fits tightly against the cable, accurately senses the tension on the cable, and converts it into an electrical signal for transmission to the intelligent controller 2. The intelligent controller 2 quickly analyzes the current tension state based on the preset tension range and control logic, and then sends precise control instructions to the hydraulic driver 3. The hydraulic driver 3, as the power source, accurately regulates the flow and pressure of the hydraulic oil after receiving the instructions, drives the drum 4 to operate smoothly, and realizes the uniform release of the cable. At the same time, the rotation speed and position information of the drum 4 will also be fed back to the intelligent controller in real time. The intelligent controller 2 is a device that can dynamically adjust the control strategy to ensure the accuracy of the cable release depth. The LCD display 1 intuitively displays the key parameters of the cable release, such as the depth, speed and tension, throughout the process, making it easy for the operator to grasp the operation progress and equipment status in real time. During the operation, if the tension sensor 5 detects abnormal cable tension, the intelligent controller 2 will immediately trigger the alarm mechanism, issue an audible and visual alarm through the LCD display 1, and quickly adjust the working state of the hydraulic drive 3 to make the drum 4 suspend the release of the cable or reverse the cable to recycle it, so as to prevent the cable from being damaged or dangerous due to excessive tension. After the cable is released, the operator can stop the drum 4 through the hydraulic drive 3; The cleaning mechanism 6 includes a rotating tube 612, on which an adjusting component for adjusting the scraper 609 is rotatably installed, and a driving component is connected to the rotating tube 612. In the process of the drum 4 releasing the cable, the driving component controls the scraper 609 to find the depression on the cable surface through the rotating tube 612; after the cable is released from the drum 4, it needs to pass through the inside of the rotating tube 612, and then extend from the inside of the rotating tube 612 to the tension sensor 5, and finally fall from the tail end of the tension sensor 5 for logging, and a torsion spring is installed at the rotating connection between the adjusting component and the rotating tube 612. With the help of the torsion spring, the scraper 609 can have a certain rotational force, which just makes the scraper 609 fit with the cable surface, so that during the transportation of the cable, impurities attached to its surface will contact the scraper 609 and be scraped off by the scraper 609, and the cleaning The cleaning mechanism 6 has its own power source and can be started by itself. When the power source is started, it will drive the rotating tube 612 to rotate back and forth slightly. The small rotation of the rotating tube 612 will drive the scraper 609 to rotate slightly, so that the scraper 609 can clean the impurities on the cable surface in a larger range. When a depression appears on the cable surface and there are impurities inside the depression, the scraper 609 can fall into the depression with the help of the torsion spring to clean the depression. The small swing of the scraper 609 can adjust the scraper 609 so that when the scraper 609 does not completely fall into the depression, it can completely fall into the depression due to the swing to clean the depression. The swing can cause the scraper 609 to scrape the depression at multiple angles, such as scraping left and right, scraping along the inside of the groove, and the movement of the cable will also cause the impurities to be squeezed with the scraper 609 to form a scraping, thereby cleaning the impurities in the depression at multiple angles. The sealing mechanism 7 includes an expansion bag 701 fixedly mounted inside the rotating tube 612 and a pressurizing assembly. A plurality of one-way valve nozzles 702 are fixedly mounted on the expansion bag 701. When the drive assembly controls the scraper 609 to swing, the pressurizing assembly is synchronously controlled to change the shape of the expansion bag 701. Once the drive assembly starts operating, it continuously supplies air to the expansion bag 701, keeping it in an inflated state. However, when encountering a recessed portion of the cable, the expansion bag 701, expanded by the pressurizing assembly, will conform to the recessed portion, thereby intercepting impurities in the recessed portion. The repair mechanism 8 includes a storage box 802 with a hole having the same diameter as the cable. The storage box 802 has a built-in nozzle 803 and a spray assembly. When the driving assembly controls the scraper 609 to swing, the nozzle 803 is synchronously controlled to spray the cable surface, and when the cable is moved out of the storage box 802, the cable surface is smoothed.

[0023] like Figure 2 and Figure 5As shown, the drive assembly includes a mounting cover 618; the motor 619 is fixedly mounted on the mounting cover 618, and a first rotating shaft 615 is fixedly mounted on its power output shaft; the third reciprocating screw rod 617 is rotatably mounted on the mounting cover 618, and a fourth bevel gear 616 is fixedly mounted on the top of the third reciprocating screw rod 617, and a threaded block 620 is threadedly connected to the bottom of the third reciprocating screw rod 617; the third bevel gear 614 is fixedly mounted on the first rotating shaft 615 and meshes with the fourth bevel gear 616; the movable column 622 is fixedly connected to the threaded block 620, and a plurality of latch teeth 621 are fixedly mounted on it; the second gear 613 is fixedly mounted on the rotating tube 612.

[0024] It should be noted that, since the cable passes through the inside of the rotating tube 612 during the release process, the motor 619 is started during the release process of the cable, and the motor 619 drives the first rotating shaft 615 to rotate. The first rotating shaft 615 rotates the third reciprocating screw rod 617 through the third bevel gear 614 and the fourth bevel gear 616. Since the movable column 622 is slidably connected to the repair mechanism 8, the third reciprocating screw rod 617 will cause the threaded block 620 to move up and down, thereby the movable column 622 also moves up and down. The up and down movement of the movable column 622 will also drive the latch 621 to move up and down. The up and down movement of the latch 621 will cause the second gear 613 to continuously rotate forward and backward at a small angle, forming a small swing, so that the rotating tube 612 also swings slightly. When the rotating tube 612 swings slightly The degree of swing will also drive the scraper 609 to swing slightly through the adjustment component. In this way, with the torsion spring, the scraper 609 itself will exert force on the surface of the cable. When the cable is released, the cable movement will interact with the scraper 609, so that the scraper 609 will clean the impurities on its surface. As the cable surface is used, there will be depressions, and impurities will remain in these depressions. The action of the torsion spring will cause the scraper 609 to fall into the depressions for cleaning, but the scraper 609 does not move to match the position of the cable depression. At this time, when the rotating tube 612 swings slightly, causing the scraper 609 to swing slightly, the scraper 609 can be completely dropped into the depression of the wire, and can even be scraped out along the inner wall of the cable depression. By scraping left and right, the impurities in the cable depression can be cleaned.

[0025] like Figures 2 to 4As shown, the adjustment assembly includes a rotating box 607 rotatably connected to the rotating tube 612, and a torsion spring is installed at the rotating connection between the rotating tube 612 and the rotating box 607; the torsion spring can rotate the rotating box 607, so that the rotating box 607 will drive the scraper 609 to rotate together, so that the scraper 609 will act on the cable surface; the first reciprocating screw rod 603 is rotatably installed inside the rotating box 607, and the second bevel gear 604 is fixedly installed on it; the motor 601 is fixedly installed on the rotating box 607, and the first bevel gear 602 meshing with the second bevel gear 604 is fixedly installed on its power output shaft; the threaded column 605 is slidably installed inside the rotating box 607 and is threadedly connected to the first reciprocating screw rod 603.

[0026] The adjustment assembly also includes a first gear 611, on which a forward and reverse screw 608 is fixedly mounted and rotatably connected to the rotating box 607; the first rack 606 is fixedly mounted on the threaded column 605 and meshes with the first gear 611; the first threaded plate 610 is slidably mounted inside the rotating box 607 and is threadedly connected to the forward and reverse screw 608, and the first threaded plate 610 is fixedly connected to the scraper 609.

[0027] It should be noted that before the rotating tube 612 drives the scraper 609 to swing slightly, the motor 601 can be started first. The motor 601 drives the first reciprocating screw 603 to rotate through the first bevel gear 602 and the second bevel gear 604. The rotation of the first reciprocating screw 603 will cause the threaded column 605 to move up and down, so that the threaded column 605 will drive the first rack 606 to move up and down. The up and down movement of the first rack 606 will cause the first gear 611 to rotate forward and backward, so that the two forward and reverse screws 608 will drive the two first threaded plates 610 to move, thereby adjusting the distance between the two first threaded plates 610. In this way, the distance between multiple scrapers 609 can be adjusted, and the scraper 60 The distances between the scrapers 609 are different in size, so that it can cope with different impurities. When the impurities encountered are generally small, the distances between the multiple scrapers 609 can be evenly distributed, and with the continuous swing of the rotating tube 612, the cable surface can be cleaned all the time. The distances between the multiple scrapers 609 are also adjusted into different styles to adapt to different environments. By reasonably setting the spacing between the scrapers 609, the scrapers 609 with smaller spacing correspond to areas with more oil and can clean the oil more carefully; the scrapers 609 with larger spacing can play a preliminary cleaning role in areas with more dust, while avoiding the accumulation of dust between the scrapers 609 due to the scrapers 609 being too dense and difficult to clean.

[0028] like Figure 6As shown, the pressurizing assembly includes a mounting box 707 fixedly connected to the mounting cover 618, and the mounting box 707 is fixedly connected to the storage box 802; the second reciprocating screw 705 is rotatably mounted inside the mounting box 707, and a second threaded plate 708 is threadedly connected thereto and is slidably connected to the mounting box 707; one end of the folding airbag 709 is fixedly mounted on the second threaded plate 708, and the other end is fixedly mounted on the mounting box 707; the one-way air inlet pipe 703 is fixedly mounted on the mounting box 707 and is connected to the folding airbag 709. The one-way air inlet pipe 703 is a foldable and retractable pipe that can be expanded or contracted as the second threaded plate 708 moves; the one-way exhaust pipe 706 is fixedly mounted on the mounting box 707, one end of which is connected to the folding airbag 709, and the other end of which is connected to the expansion airbag 701; the worm 704 connects the second reciprocating screw 705 to the first rotating shaft 615.

[0029] It should be noted that when the cable enters the rotating tube 612, it will be squeezed and contacted with the expansion airbag 701 inside the rotating tube 612. In this way, the impurities on the cable surface cleaned by the scraper 609, if not completely fallen off, can also be intercepted by the expansion airbag 701. When the motor 619 drives the first rotating shaft 615 to rotate, the first rotating shaft 615 will rotate the second reciprocating screw 705 through the worm 704. The rotation of the second reciprocating screw 705 will cause the second threaded plate 708 to move back and forth inside the installation box 707. The reciprocating movement of the installation box 707 will continuously squeeze the folded airbag 709, causing the folded airbag 709 to continuously compress and inhale gas. Due to the setting of the one-way air inlet pipe 703 and the one-way exhaust pipe 706, the gas compressed by the folded airbag 709 can only be discharged from the one-way exhaust pipe 706, and the discharged gas will enter the interior of the expansion airbag 701, causing the expansion airbag 701 to be inflated all the time. 701 is always in an expanded state, so even if the expansion airbag 701 is worn during use, it can still contact the cable and will not affect the cleaning effect. When encountering a depression in the cable, the expansion of the expansion airbag 701 will make the expansion airbag 701 fit together with the depression of the cable, thereby cleaning and intercepting the depression of the cable and further intercepting impurities. A one-way valve mouth 702 is provided on the expansion airbag 701. The one-way valve mouth 702 requires a certain amount of pressure to open, which can ensure that the expansion airbag 701 is always in an expanded state. When the air pressure inside the expansion airbag 701 reaches a certain value, the gas will be discharged from the one-way valve mouth 702. The one-way valve mouth 702 is also installed at an angle and can be aimed at the cable. The impurities remaining on the surface of the cable are cleaned with the help of the ejected gas, and the one-way valve mouth 702 will also swing continuously with the rotating tube 612, so that the ejected gas will also swing to clean the cable.

[0030] like Figure 7As shown, the injection assembly includes a partition 805 fixedly connected to the storage box 802, and the partition 805 is fixedly connected to the nozzle 803; an ordinary screw 806 is rotatably installed on the storage box 802, and a worm gear 801 engaged with the worm 704 is fixedly installed on it; a pressure plate 804 is slidably installed inside the storage box 802 and is threadedly connected to the ordinary screw 806.

[0031] It should be noted that when the cable enters the worm gear 801 after being cleaned by the scraper 609 and the expansion airbag 701, the worm gear 704 is driven by the motor 619, and the worm gear 704 also causes the ordinary screw 806 to rotate through the worm gear 801. The rotation of the ordinary screw 806 causes the pressing plate 804 to continuously move upwards. In this way, the pressing plate 804 can discharge the repair material inside the storage box 802 into the inside of the nozzle 803. The material entering the nozzle 803 will be sprayed onto the surface of the cable to repair the dents on the cable surface. The diameter of the opening on the storage box 802 is the same as the diameter of the standard cable. In this way, when the cable is removed after being sprayed, it can contact the opening to scrape off the excess paint on the cable, so that the diameter of the cable will be the same as the diameter of the standard cable. The scraping will cause the excess paint to continue to move along the cable, and the over-sprayed material will be smoothed back. Even if the sprayed material is uneven, or there is not enough material sprayed in some depressions, it can be evenly covered during the smoothing process. In this way, the diameter of the cable out of the hollow box will be the same as the diameter of the standard cable.

[0032] like Figure 8 As shown, a curing mechanism 9 is fixedly mounted on the worm gear 801; the curing mechanism 9 includes a micro generator 901 fixedly connected to the storage box 802, and the drive shaft of the micro generator 901 is fixedly connected to the second reciprocating screw 705; a fixed cover 903 is fixedly mounted on the storage box 802, and its upper opening is aligned with the opening on the worm gear 801; an adjustment assembly is fixedly mounted on the fixed cover 903; and an ultraviolet curing lamp 904 is fixedly mounted on the adjustment assembly.

[0033] It should be noted that after the motor 619 is started, it can drive the second reciprocating screw 705 to rotate. The rotation of the second reciprocating screw 705 will start the micro-generator 901. The micro-generator 901 is electrically connected to the regulating mechanism. As the micro-generator 901 starts, it generates electricity, which is transmitted to the regulating mechanism, thereby causing the regulating mechanism to adjust the ultraviolet curing lamp 904. Since the conveying speed of the cable can be fast or slow, the motor 619 can be set to a motor controlled by the controller so that the conveying speed of the cable by the motor 619 and the roller 4 can match each other. In this way, when the cable is released quickly, the rotating tube 612 is driven quickly, so that the scraper 609 can be quickly fine-tuned and cleaned quickly, and the spraying speed of the nozzle 803 becomes faster, spraying a large amount of paint to meet the needs of repairing the cable, thereby meeting its needs. On the contrary, if the speed is slow, it can also be slowed down accordingly to match each other.

[0034] like Figure 9 As shown, the adjustment assembly includes a fixed tube 902 fixedly connected to a fixed cover 903; an electromagnet 906 is fixedly mounted on the fixed tube 902; a permanent magnet 907 is slidably mounted inside the fixed tube 902, on which is mounted a connecting rod 909 fixedly connected to a UV curing lamp 904; a spring 908 is sleeved on the connecting rod 909, one end of the spring 908 is fixedly connected to the permanent magnet 907, and the other end of the permanent magnet 907 is fixedly connected to the fixed cover 903.

[0035] It should be noted that, since the magnetic force of the electromagnet 906 after being energized repels the magnetic force of the permanent magnet 907, the magnitude of the magnetic force of the electromagnet 906 is controlled by the magnitude of the current delivered by the micro-generator 901, and the magnitude of the current delivered by the micro-generator 901 is controlled by the rotation speed of the motor 619. When the cable conveying speed increases, the magnetic force of the electromagnet 906 increases, so that the permanent magnet 907 will be further away from the electromagnet 906, thereby allowing the ultraviolet curing lamp 904 to get closer to the cable, and can cure the repair material on the cable more quickly, adapting to the situation of fast cable conveying speed. On the contrary, when the cable conveying speed is slow, the ultraviolet curing lamp 904 can be kept away from it, avoiding excessive irradiation that is not conducive to the molding of the material.

[0036] like Figure 10 and Figure 11 As shown, a rotating base 913 is fixedly mounted on the ultraviolet curing lamp 904, a second rotating shaft 912 is rotatably mounted on the rotating base 913, a reflector 910 and a third gear 905 are fixedly mounted on the second rotating shaft 912, a second rack 911 is meshed with the third gear 905, and the second rack 911 is fixedly connected to the fixed cover 903.

[0037] It should be noted that when the ultraviolet curing lamp 904 moves due to the action of the electromagnet 906, the ultraviolet curing lamp 904 will also drive the reflector 910 to move. The movement of the reflector 910 will drive the third gear 905 to move. The movement of the third gear 905 will rotate due to the action of the second rack 911, thereby rotating the second rotating shaft 912, and the rotation of the second rotating shaft 912 will rotate the reflector 910. When the cable moves slowly, the angle of the reflector 910 is small, so that the ultraviolet lamp is focused on the unit area of the cable surface, increasing the light intensity, and compensating for the problem of short irradiation time caused by the rapid movement of the cable. When the cable moves slowly, the angle of the reflector 910 is relatively large, which expands the light coverage range, ensures that the cable surface is evenly illuminated, and improves the uniformity of curing.

[0038] Working principle: During logging operations, the intelligent controller 2 serves as the core, receives the cable tension electrical signal transmitted by the tension sensor 5, sends instructions to the hydraulic driver 3 according to the preset logic, adjusts the hydraulic oil flow and pressure, drives the drum 4 to release or retract the cable, and the LCD 1 displays the depth, speed, tension and other parameters in real time; if the tension is abnormal, the intelligent controller 2 triggers an alarm and adjusts the hydraulic driver 3 to make the drum 4 pause or reverse; when the cable is released, it passes through the rotating tube 612, and the motor 619 drives the first rotating shaft 615 to rotate, which is connected to the third bevel gear 614 through the rotating tube 612. The fourth bevel gear 616 is engaged to drive the third reciprocating screw 617 to rotate, so that the threaded block 620 and the movable column 622 move up and down, and the latch 621 pushes the second gear 613 to drive the rotating tube 612 to swing slightly; the scraper 609 in the rotating tube 612 is attached to the cable through the torsion spring, scraping impurities at multiple angles when swinging, and the motor 601 drives the first bevel gear 602 to engage with the second bevel gear 604 to drive the first reciprocating screw 603 to rotate, and the adjustment threaded column 605 and the first rack 606 move, through the first gear 611 and the forward and reverse screw 608 Adjust the spacing of the first threaded plate 610 and change the spacing of the scraper 609 to adapt to different impurities; at the same time, the first rotating shaft 615 drives the second reciprocating screw 705 to rotate through the worm 704, so that the second threaded plate 708 moves back and forth to squeeze the folded airbag 709, and supplies air to the expansion airbag 701 through the one-way air inlet pipe 703 and the one-way exhaust pipe 706, so that it expands and fits the cable to intercept impurities, and the one-way valve nozzle 702 sprays air to sweep away the remaining impurities; after cleaning, the cable enters the storage box 802, and the worm 704 drives the worm wheel 801 and the ordinary screw 806 to rotate, pushing the compression Plate 804 sprays the repair material onto the recessed area of the cable through nozzle 803, and the storage box 802 is opened to scrape off excess paint and smooth it out; the worm gear 801 drives the micro generator 901 to generate electricity, and the current controls the magnetic force of the electromagnet 906, pushing the permanent magnet 907 and the connecting rod 909 to move the ultraviolet curing lamp 904 closer to or away from the cable. At the same time, the movement of the ultraviolet curing lamp 904 drives the second rotating shaft 912 and the third gear 905 to rotate. The reflector 910 adjusts the angle by meshing with the second rack 911 to achieve light focusing or diffusion, so that the repair material can be cured quickly and evenly.
