[0002] Intelligent workover rigs are modern workover equipment that integrates technologies such as automated control, intelligent sensing, data analysis and decision-making. Through sensors, the Internet of Things, artificial intelligence and other means, they can realize remote monitoring, automatic execution and intelligent optimization of oil and gas well workover operations. They are one of the core equipment for the digital transformation of the oil and gas industry.

[0003] To facilitate the movement of the workover rig, a loading vehicle is typically used to support the rig frame. The rig is then deployed or retracted using a robotic arm and drive cylinders, positioning it in a designated location for the workover system. However, during operation, the weight of the workover system and the rig itself acts on the robotic arm, drive cylinders, and loading vehicle. To ensure operational stability, counterweights are usually mounted on the loading vehicle. Nevertheless, the weight of the rig and the workover system is still transmitted to the robotic arm and drive cylinders, accelerating their wear and tear. Furthermore, when the rig is overloaded, it may tip over.

[0004] Therefore, an intelligent well-servicing machine and its operation method are proposed to solve or alleviate the above problems. Summary of the Invention

This allows the support plate to align with the second plate, and the support plate drives the second plate to move toward the support plate on the mounting housing. This causes the support plate to move toward a vertical position, thereby enabling the support plate to support and protect the frame through the first plate, the fixed plate, and the steel plate, thus completing the frame support. Step 3: When the well workover unit is being used for well workover operations, the changes in the values ​​detected by the detection sensors are compared to determine whether the values ​​detected by the detection sensors exceed the safety threshold range.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figures 1-8 The diagram shows an intelligent well-servicing machine and its operation method.

[0021] Example 1: Includes a loading vehicle 1, a frame 2, steel plates 4, a base plate 5, a support plate 6, a support assembly 7, and an adjustment assembly 8. The frame 2 is mounted on the loading vehicle 1. A well workover unit 3 is mounted on the front of the frame 2. The loading vehicle 1 drives the frame 2 to unfold vertically, allowing the well workover unit 3 to flush, expand, or unclog and repair the oil well. The loading vehicle 1 is equipped with a control terminal for controlling the operation of the frame 2 and the well workover unit 3. This is prior art and will not be described in detail here. The steel plates 4 are symmetrically fixed to the bottom of the frame 2. One side of the base plate 5 is located at the bottom of the loading vehicle 1, ensuring the stability of the base plate 5 on the ground. The bottom of the outer wall of the support plate 6 is connected to the base plate. 5. Sliding engagement: The bottom plate 5 is fixedly connected to the top of the binding frame, so that the bottom of the outer wall of the support plate 6 is slidably engaged with the binding frame, thereby realizing the docking of the support plate 6 and the bottom plate 5. The support component 7 is set between the support plate 6 and the steel plate 4. The adjustment component 8 is set on one side of the support plate 6. The adjustment component 8 is used to adjust the supporting force of the support plate 6 on the steel plate 4 through the support component 7. Thus, under the action of the adjustment component 8 and the support component 7, the support plate 6 can support and protect the frame 2 through the steel plate 4. When the frame 2 drives the well repair unit 3 to work, the frame 2 is in a stationary state, thereby avoiding the support plate 6 from affecting the operation of the frame 2 when supporting the frame 2.

[0022] Furthermore, the support assembly 7 includes a fixed plate 71, a sliding hole 72, a first plate 73, a positioning block 74, a second plate 75, a support plate 76, and a hinge 77. One side of the fixed plate 71 is fixedly connected to the steel plate 4. The sliding hole 72 is opened on one side of the support plate 6. The outer wall of the fixed plate 71 is slidably fitted with the sliding hole 72, and the sliding hole 72 has a certain length to facilitate the docking and installation of the support plate 6. The first plate 73 is slidably disposed on one side of the support plate 6, and the top of the first plate 73 is in contact with the fixed plate 71. The positioning block 74 is fixedly connected to the top of the first plate 73. The bottom of the fixed plate 71 has a positioning hole, and the outer wall of the positioning block 74 slides and engages with the inner cavity of the positioning hole. Under the action of the positioning block 74, the stability of the first plate 73 engaged with the bottom of the fixed plate 71 can be ensured, and the first plate 73 can also engage and limit the support plate 6, thereby ensuring the stability of the top of the support plate 6 and the steel plate 4. The second plate 75 is set on the top of the adjusting assembly 8. The top of the support plate 76 is rotatably connected to the first plate 73 through the hinge 77, and the bottom of the support plate 76 is rotatably connected to the second plate 75 through the hinge 77. Figure 3 As shown, when the support plate 76 tends to move vertically and the bottom height of the support plate 76 remains unchanged, the top height of the support plate 76 can be adjusted so that the support plate 6 supports the steel plate 4 through the support plate 76 and the fixing plate 71.

[0023] Example 2: Based on Example 1, the adjustment component 8 includes a mounting housing 81, an integrated bracket 82, a connector 83, a docking component 84, an adjusting screw 85, and a drive unit 86. The mounting housing 81 is slidably engaged with one side of the support plate 6 via the integrated bracket 82. Under the action of the integrated bracket 82, the stability of the mounting housing 81 mounted on one side of the support plate 6 can be ensured. The connector 83 is slidably disposed inside the mounting housing 81. The top of the mounting housing 81 has a connection hole corresponding to the connector 83, so that the connector 83 can be positioned relative to the mounting housing. Body 81 slides, docking assembly 84 is installed on top of connector 83, docking assembly 84 is connected to second plate 75, adjusting screw 85 is rotatably installed inside mounting housing 81, outer wall of adjusting screw 85 is threadedly connected to connector 83, drive unit 86 is installed at end of adjusting screw 85, when drive unit 86 drives adjusting screw 85 to rotate, adjusting screw 85 can drive connector 83 to slide inside mounting housing 81, thereby causing connector 83 to drive bottom of support plate 76 to slide on mounting housing 81 through docking assembly 84.

[0024] Specifically, the docking assembly 84 includes a support plate 841, a detection sensor 842, and a limiting block 843. The support plate 841 is fixedly connected to the top of the connector 83. The support plate 841 and the side opposite to the second plate 75 are provided with corresponding inclined slopes, such as... Figure 5 and Figure 6 As shown, when the second plate 75 is located on top of the support plate 841, its corresponding inclined slope allows the support plate 841 to better push the second plate 75 to move on the mounting housing 81. The detection sensor 842 is fixedly installed on the top of the support plate 841, with its top in contact with the second plate 75. The detection sensor 842 is a pressure sensor that can detect the compressive force between the second plate 75 and the support plate 841, thereby detecting the change in the force between the support plate 6 and the frame 2. 842 can transmit the detected data to the control terminal of the loading vehicle 1 via wireless communication technology. The limiting block 843 is fixedly connected to the bottom of the second plate 75. The top of the support plate 841 is provided with a limiting groove 844. The outer wall of the limiting block 843 is slidably engaged with the inner cavity of the limiting groove 844. The limiting block 843 can improve the stability of the connection between the second plate 75 and the support plate 841. Moreover, the bottom of the limiting block 843 does not fit with the bottom of the inner wall of the limiting groove 844, thereby avoiding affecting the value detected by the detection sensor 842.

[0025] Furthermore, the integrated bracket 82 includes a support block 821, a locking block 822, a third plate 823, a triangular plate 824, a snap-fit ​​component 825, and a slot 826. The support block 821 is fixedly connected to one side of the support plate 6, and the top of the support block 821 is in contact with the mounting housing 81. The locking block 822 is fixedly connected to the bottom of the mounting housing 81, and a locking hole is provided on the top of the support block 821. The outer wall of the locking block 822 is slidably engaged with the inner cavity of the locking hole. Under the action of the support block 821 and the locking block 822, the stability of the connection between the bottom side of the mounting housing 81 and the support plate 6 can be improved. The third plate 823 is disposed on one side of the support plate 6, the triangular plate 824 is fixedly connected between the third plate 823 and the mounting housing 81, and the snap-fit ​​component 825 is fixedly connected to the third plate 823 facing the support plate 6. On one side of the protective plate 6, a slot 826 is formed on one side of the support plate 6. The outer wall of the snap-fit ​​member 825 is slidably snapped into the inner cavity of the slot 826. The snap-fit ​​member 825 has an L-shaped cross-section, and a recessed part is provided on one side of the bottom of the inner wall of the slot 826, which can ensure the stability of the snap-fit ​​member 825 and the slot 826. Under the action of the third plate 823, the triangular plate 824 and the snap-fit ​​member 825, the stability of the other side of the bottom of the mounting housing 81 can be ensured. After the support assembly 7 is disassembled, the mounting housing 81 is lifted, so that the locking block 822 is separated from the bearing block 821. At this time, the snap-fit ​​member 825 is separated from the bottom of the inner cavity of the slot 826, that is, the snap-fit ​​state of the snap-fit ​​member 825 and the slot 826 is released. The mounting housing 81 can be disassembled by moving away from the support plate 6.

[0026] Furthermore, the drive unit 86 includes a fixed cap 861, a drive block 862, a wedge 865, a mounting groove 863, a mating groove 864, a limiting bolt 866, and a limiting spring 867. The fixed cap 861 is fixedly connected to the end of the adjusting screw 85. The drive block 862 is rotatably sleeved inside the fixed cap 861. A rectangular groove is formed on one side of the drive block 862. The wedges 865 are arranged in a circular array between the drive block 862 and the fixed cap 861. The mounting groove 863 is formed outside the drive block 862. One end of the outer wall of the wedge 865 is slidably sleeved inside the mounting groove 863. The mating groove 864 is formed inside the fixed cap 861. The other end of the outer wall of the wedge 865 is slidably engaged with the mating groove 864. One side of the wedge 865 has a slope, and one side of the inner cavity of the mating groove 864 also has an inclined slope. Figure 8 As shown, one end of the wedge 865 has a bolt hole. One end of the outer wall of the limiting bolt 866 is slidably engaged with the bolt hole, and the other end of the outer wall of the limiting bolt 866 is threadedly connected to the drive block 862. The limiting spring 867 is slidably sleeved on the outside of the limiting bolt 866, and one end of the limiting spring 867 is pressed against the wedge 865. The wedge 865 can slide relative to the limiting bolt 866 toward the inside of the mounting groove 863, but under the restriction of the limiting bolt 866, the wedge 865... It cannot slide directly into the mounting slot 863, and the limiting spring 867 acts on the wedge 865 with an elastic compressive force. Therefore, when an electric wrench is used to engage with the rectangular slot on the front of the drive block 862, causing the drive block 862 to rotate clockwise, the drive block 862 can drive the fixing cap 861 and the adjusting screw 85 to rotate through the resistance between the wedge 865 and the fixing cap 861. As the adjusting screw 85 rotates, the support plate 76 gradually increases its support for the fixing plate 71, and the adjusting screw 85... The resistance between the connecting parts 83 increases accordingly. When the rotational resistance between the adjusting screw 85 and the connecting part 83 is greater than the resistance between the multiple wedges 865 and the fixing cap 861, the driving block 862 rotates relative to the fixing cap 861 and no longer drives the adjusting screw 85 to rotate, thus completing the adjustment of the support plate 76. When selecting the limit spring 867, it is necessary to select a limit spring 867 with a suitable elastic coefficient according to the rotational resistance requirement between the adjusting screw 85 and the connecting part 83, so that the driving block 862 can drive the adjusting screw 85 to rotate to the specified state through the wedges 865 and the fixing cap 861. That is, the supporting force between the support plate 76 and the fixing plate 71 meets the support requirement of the support plate 6 for the frame 2. When the driving block 862 rotates counterclockwise, the driving block 862 can engage the driving fixing cap 861 through the smooth side of the wedge 865, preventing the driving block 862 from rotating relative to the fixing cap 861, so as to ensure that the adjusting screw 85 can drive the connecting part 83 to move and reset.

[0027] Another objective of this invention is to provide an operating method for an intelligent well workover rig, comprising the following specific steps: Step 1: When performing well repair operations, the loader 1 moves the frame 2 to the wellhead and places the base plate 5 on the ground. The loader 1 then presses and limits the base plate 5. The loader 1 then drives the frame 2 to unfold, making the frame 2 vertical. The support plate 6 is then attached to one side of the steel plate 4, so that the fixing plate 71 is located inside the sliding hole 72. The support plate 6 is then lowered so that the bottom of the support plate 6 slides and engages with the base plate 5. Step 2: After the support plate 6 is connected, the mounting housing 81 is snapped onto one side of the support plate 6 by the integrated bracket 82. Then, the first plate 73 is snapped onto the bottom of the fixed plate 71 by the positioning block 74. Then, the driving unit 86 drives the adjusting screw 85 to rotate, so that the adjusting screw 85 drives the connecting piece 83 and the support plate 841 to slide on the mounting housing 81, so that the support plate 841 connects with the second plate 75. The support plate 841 drives the second plate 75 to move towards the support plate 6 on the mounting housing 81, so that the support plate 76 tends to move into a vertical state. Then, the support plate 76 supports and protects the frame 2 through the first plate 73, the fixed plate 71 and the steel plate 4, thus completing the support of the frame 2. Step 3: When the workover unit 3 is being used on one side of the frame 2 for workover operations, compare the changes in the values ​​detected by the detection sensor 842 to determine whether the values ​​detected by the detection sensor 842 exceed the safety threshold range. The safety threshold range refers to the maximum and minimum safety thresholds when the frame 2 drives the workover unit 3 to work, and the support plate 6 supports the frame 2 through the support component 7 and the adjustment component 8. That is, when the weight of the frame 2 acting on the support plate 6 is greater than the maximum safety threshold, the frame 2 has a tendency to tilt forward; when the weight of the frame 2 acting on the support plate 6 is less than the minimum safety threshold, the frame 2 has a tendency to tilt backward. If the value detected by the detection sensor 842 exceeds the safety threshold, the operation should be stopped immediately.
