Description

Technical Field

[0001] This invention relates to the field of petroleum equipment and engineering machinery technology, and in particular to an automatic adjustment system and method for the tilt angle of a two-level drilling and workover control platform. Background Technology

[0002] In the field of petroleum equipment and engineering machinery, the leveling of the second-level operating platform mainly relies on manual pre-adjustment of the wire rope length. The wire rope adjustment is generally performed when the derrick is level or nearly level. After adjustment, the derrick is raised, causing the second-level platform to rotate to a level position to verify the adjustment effect. The initial calculated length of the wire rope often has a significant error compared to the actual length due to the different angles and tensions of multiple pulleys, requiring multiple adjustments and making it impossible to guarantee the leveling error of the second-level operating platform. With the development of automation and intelligence in fields such as petroleum equipment and machinery, reducing manual labor intensity and avoiding repetitive operations through intelligent control systems, and developing highly efficient, intelligent, integrated, and multifunctional equipment are the current mainstream development direction. For the leveling of the second-level operating platform, there is an urgent need for an automatic tilt adjustment system to improve the convenience of on-site operations and ensure on-site safety.

[0003] Chinese invention patent, publication number CN116480294A, entitled "Drilling and Workover Derrick Assembly," discloses a drilling and workover derrick assembly including a derrick body, a front two-tier platform, and a rear two-tier platform. The lower end of the derrick body is adapted to connect to the drill platform surface. The front and rear two-tier platforms are respectively located on the front and rear sides of the derrick body and are both adapted to move in the vertical direction. Both the front and rear two-tier platforms are adapted to form a working plane and to install a tubing handling system. In this technical solution, the working plane formed by the front and rear two-tier platforms and the tubing handling system allow for offline drill pipe connection and erection operations, thereby improving the operation speed. However, this technical solution cannot adjust the angle of the second-tier operating platform, cannot reduce manual labor intensity, and cannot improve the convenience of on-site operations. Summary of the Invention

[0004] To address the problem in the prior art that the manual adjustment of the second-level control platform for drilling and well repair requires multiple adjustments, resulting in repetitive operations and high labor intensity, this invention proposes an automatic adjustment system and method for the tilt angle of the second-level control platform for drilling and well repair.

[0005] This invention is achieved through the following technical solution: It includes a derrick and a second-level operating platform located in the middle of the derrick. One side of the second-level operating platform in the width direction is rotatably connected to the derrick. It also includes a rope winding system, which comprises a steel rope, a pulley block located at the top of the derrick and fixedly connected to it, a movable pulley located in the lower middle part of the derrick, and a second fixed pulley located at the top of the second-level operating platform away from the derrick and fixedly connected to it. The two ends of the steel rope are respectively fixed to the top of the derrick and the top of the second-level operating platform away from the derrick. Starting from a fixed point at the top of the derrick, the steel rope sequentially passes around the second fixed pulley, the pulley block, the movable pulley, and the pulley block again. The system is finally fixed to a fixed point at the top of the second-level operating platform, away from the derrick. A tensioning device is also installed on one side of the derrick. The tensioning rope of the tensioning device is fixedly connected to a transmission device via a first fixed pulley located at the bottom of the derrick. The transmission device is located above the first fixed pulley and fixedly connected to the derrick. The other end of the transmission device is fixedly connected to a movable pulley. An inclination sensor is installed on the second-level operating platform. The derrick consists of two sections: the section closer to the ground is the first section, and the section further away from the ground is the second section. The second-level operating platform is connected to the top of the first section of the derrick. The system also includes a driller's control system, which is electrically connected to the tensioning device and the inclination sensor.

[0006] As a further preferred embodiment, the rope winding system consists of two sets, symmetrically arranged with respect to the centerline of the width direction of the second-level operating platform.

[0007] As a further preferred embodiment, a clamping device is provided between the transmission device and the movable pulley, and the clamping device is connected to the driller's control system via an electrical signal.

[0008] As a further preferred embodiment, a fixing device is fixedly connected to the derrick at the relative position of the movable pulley, and the fixing device is connected to the driller's control system via an electrical signal.

[0009] As a further preferred embodiment, an axial force sensor is installed between the pulley block and the derrick, and the axial force sensor is connected to the driller's control system via an electrical signal.

[0010] As a further preferred embodiment, the automatic tilt adjustment system for the second-level drilling and workover control platform also includes a remote control system, which is connected to the driller's control system via electrical signals.

[0011] The present invention also provides an adjustment method applicable to the automatic tilt adjustment system of the drilling and workover control platform on the second level as described in the present invention, comprising the following steps:

[0012] S1. In the initial state of the derrick, the length of the adjusting steel cable remains consistent;

[0013] S2. The first section of the derrick rotates and lifts to the set position;

[0014] S3. The second section of the derrick extends, and the second-floor operating platform rotates away from the derrick along with the rope winding system until the second section of the derrick is fully extended.

[0015] S4. The driller's control system sends an opening control signal to the clamping device, and the clamping device opens.

[0016] S5. The tilt sensor transmits tilt data to the driller's control system in real time. The driller's control system sends corresponding control signals to the tensioning device based on the tilt data. If the tilt data is greater than the set value, the driller's control system sends a tightening control signal to the tensioning device, which tightens, causing the movable pulley to move towards the bottom of the derrick via the transmission device, and the second-level operating platform slowly rotates towards the derrick. If the tilt data is less than the set value, the driller's control system sends a release control signal to the tensioning device, which releases, causing the movable pulley to move towards the top of the derrick via the transmission device, and the second-level operating platform slowly rotates away from the derrick. If the tilt data is equal to the set value, the driller's control system sends a closing control signal to the tensioning device.

[0017] S6. The driller's control system sends a shutdown control signal to the clamping device;

[0018] S7. When the derrick needs to be moved for transportation, the driller's control system sends an opening control signal to the clamping device;

[0019] S8. The driller's control system sends a tightening control signal to the tensioning device, which begins to tighten slowly. The transmission device causes the movable pulley to move towards the bottom of the derrick, and the second-level operating platform slowly rotates towards the derrick.

[0020] S9. When the tensioning device reaches the set maximum tension, the driller's control system sends a shutdown control signal to the tensioning device.

[0021] S11. The driller's control system sends a shutdown control signal to the clamping device;

[0022] S12. The second section of the derrick is retracted until it overlaps with the first section of the derrick.

[0023] S13. The first section of the derrick rotates horizontally and lowers until it is horizontal.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The automatic tilt adjustment system and method for the second-level control panel of the drilling and well repair system designed in this invention has a compact structure and a simple and reliable method. Operators can adjust the tilt angle independently in a safe area using a remote control panel, or they can operate it from the driller's cabin or the driller's box central control point.

[0026] 2. The automatic tilt adjustment method for the second-level operating platform of the drilling and well repair system designed in this invention can be used in conjunction with a level detection system to complete the precise leveling action of the second-level operating platform. This reduces the repetitive leveling work caused by the level of the second-level operating platform, avoids safety hazards caused by leveling problems, reduces the workload of on-site workers, and improves the efficiency of equipment installation and commissioning.

[0027] 3. The tilt angle of the drilling and well repair workover platform designed in this invention can be automatically adjusted, making the overall system safer, more reliable, and more intelligent. Attached Figure Description

[0033] The advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, this invention provides an automatic tilt adjustment system for a two-level operating platform in drilling and workover, including a derrick 11 and a two-level operating platform 12 disposed in the middle of the derrick 11. One side of the two-level operating platform 12 in the width direction is rotatably connected to the derrick 11. The adjustment system also includes a rope winding system, which includes a steel rope 9, a pulley block 10, a movable pulley 5, and a second fixed pulley 13. The pulley block 10 is disposed on the top of the derrick 11 and fixedly connected to the derrick 11. The second fixed pulley 13 is disposed on the top of the two-level operating platform 12 at the end away from the derrick 11 and fixedly connected to the two-level operating platform 12. The movable pulley 5 is disposed in the lower part of the derrick 11. The two ends of the steel rope 9 are respectively fixed to the top of the derrick 11 and the top of the two-level operating platform 12 at the end away from the derrick 11, i.e. Figure 1The steel cable 9 is divided into two parts: A and B. Part A is the top of the derrick 11, and part B is the top of the second-level operating platform 12 at the end furthest from the derrick 11. Parts A and B can also be referred to as the dead points of the steel cable 9. The steel cable 9 starts from the fixed point at the top of the derrick 11, goes around the second fixed pulley 13 on the second-level operating platform 12, returns to the pulley group 10 at the top of the derrick 11, goes around the pulley group 10 at the top of the derrick 11, goes to the movable pulley 5 in the lower middle part of the derrick 11, goes around the movable pulley 5 in the lower middle part of the derrick 11, goes to the pulley group 10 at the top of the derrick 11, goes around the pulley group 10 at the top of the derrick 11, and goes to the fixed point at the top of the second-level operating platform 12 at the end furthest from the derrick 11. The steel cable 9 starts from a fixed point at the top of the derrick 11, passes sequentially around the second fixed pulley 13, pulley block 10, movable pulley 5, and pulley block 10 again, and is finally fixed to a fixed point at the top of the second-level operating platform 12, away from the derrick 11. The derrick 11 generally consists of two sections: the section closer to the ground is the first section, and the section further away from the ground is the second section. The second-level operating platform 12 is connected to the top of the first section of the derrick 11. In the initial state, i.e., horizontal or nearly horizontal, the two sections of the derrick 11 overlap. During operation, the first section of the derrick 11 first rotates and rises. At this time, the relative position of the second-level operating platform 12 and the derrick 11 generally does not change or changes very little. When the first section of the derrick 11 rotates to the specified angle, the second section of the derrick 11 begins to extend. At this time, the second-level operating platform 12 rotates synchronously with the rope winding system to the target position. After it is fully extended, fine adjustments are made to ensure that the second-level operating platform 12 is horizontal. Because the adjustment of steel cable 9 may have errors or be incomplete, during the rotation and lifting of the first section of the derrick 11, the second-level operating platform 12 will rotate synchronously with the rope winding system by approximately 10°.

[0035] The tension of the steel rope 9 can adjust the horizontal angle of the second-level operating platform 12. Preferably, there are two sets of the rope winding system, symmetrically arranged with respect to the centerline of the width direction of the second-level operating platform 12. Different adjustments to the two steel ropes 9 can achieve different left and right horizontal angles and force conditions for the second-level operating platform 12.

[0036] A tensioning device 1 is also provided on one side of the derrick 11. The tensioning rope of the tensioning device 1 is fixedly connected to the transmission device 3 via a first fixed pulley 2 located at the bottom of the derrick 11. The transmission device 3 is located above the first fixed pulley 2 and is fixedly connected to the derrick 11. The other end of the transmission device 3 is fixedly connected to a movable pulley 5. In order to lock the steel rope 9 after adjustment and to prevent the tensioning device 1 from being in a working state for a long time and thus shortening its service life, a clamping device 4 can be provided between the transmission device 3 and the movable pulley 5.

[0037] like Figure 3As shown, a fixing device 6 can be installed at the relative position of the movable pulley 5. The relative position of the movable pulley 5 is the distance the movable pulley 5 moves under the maximum and minimum tension of the tensioning device 1. The fixing device 6 is fixedly connected to the derrick 11. The fixing device 6 is a safety device, and like the clamping device 4, it is a locking structure that can lock the movable pulley 5 in a fixed position on the derrick 11. When the second-level operating platform 12 is adjusted into place, during transportation, or when an emergency stop is required, the fixing device 6 can be used for safe fixing.

[0038] The tensioning device 1 can adjust the position of the movable pulley 5 through the transmission device 3. The movement of the movable pulley 5 can drive the steel rope 9 to perform tensioning and other adjustment actions.

[0039] An inclination sensor 7 is installed on the second-level operating platform 12. The inclination sensor 7 can record the inclination data between the second-level operating platform 12 and the derrick 11 in real time and transmit it to the driller's control system. When the feedback data does not match the preset data, the driller's control system can directly or indirectly control the tensioning device 1 to adjust the position of the movable pulley 5 through an electrical signal via a remote control system, and then adjust the inclination value of the second-level operating platform 12 through the steel cable 9.

[0040] An axial force sensor 8 can also be installed between the pulley block 10 and the derrick 11. The axial force sensor 8 and the tensioning device 1 can provide feedback on the magnitude of the force borne by the steel rope 9. By sensing the difference in the magnitude of the force borne by the two steel ropes 9, the two steel ropes 9 can be adjusted individually. When the error of the force value transmitted by the axial force sensor 8 is greater than the preset value, the driller's control system will alarm the operator to ensure the balance on both sides of the second-level operating platform 12 under working force conditions, and at the same time ensure the safety of the operators above the second-level operating platform 12.

[0041] Based on existing control adjustments and working habits, after leveling the second-level control panel 12, it was necessary to stand at a considerable distance to the side of the entire vehicle to observe its angle and other conditions. Adding a remote control system allows for the transmission and reception of electrical signals to link with the driller's control system, enabling operation from a greater distance from the vehicle. This better suits on-site operating habits and significantly increases the convenience of on-site operations.

[0042] When the vehicle needs to be moved to another location for transportation, the tensioning device 1 can tighten the steel rope 9 to the maximum extent through the transmission device 3. At this time, the second-level operating platform 12 can be securely fixed on the derrick 11 in a reasonable position, ensuring the height of transportation and reducing safety hazards during transportation.

[0043] Once the horizontal angle of the second-level operating platform 12 is adjusted and the force on both sides is normal, consider locking the position of the second-level operating platform 12. The driller's control system can directly or indirectly control the locking device 4 to lock the transmission device 3 via electrical signals through the remote control system. Similarly, when the position needs to be adjusted next time, the locking device 4 needs to be released to lock the transmission device 3.

[0044] The automatic tilt adjustment system for the second-level drilling and workover control platform also includes a driller's control system and a remote control system. The driller's control system is electrically connected to the tensioning device 1, clamping device 4, fixing device 6, tilt sensor 7, axial force sensor 8, and remote control system. It receives force values ​​transmitted from the tensioning device 1 and axial force sensor 8, tilt angle data between the second-level control platform 12 and the derrick 11 transmitted from the tilt sensor 7, control signals transmitted from the remote control system, and opening and closing control signals sent to the clamping device 4, fixing device 6, and tensioning device 1. The driller's control system can also send force values ​​and tilt angle data to the remote control system. The remote control system is electrically connected to the driller's control system and indirectly controls the tensioning device 1, clamping device 4, and fixing device 6.

[0045] The present invention also provides an adjustment method applicable to the automatic tilt adjustment system of the drilling and workover control platform on the second level as described in the present invention, comprising the following steps:

[0046] Step 1: In the initial state of the derrick 11, adjust the length of the steel cable 9 to keep it consistent.

[0047] Step 2: The first section of the derrick 11 is rotated and lifted to the set position.

[0048] Step 3: The second section of the derrick 11 extends, and the second-level operating platform 12 rotates away from the derrick 11 along with the rope winding system until the second section of the derrick 11 is fully extended.

[0049] Step 4: The driller's control system sends an opening control signal to the clamping device 4, and the clamping device 4 opens.

[0050] Step 5: The tilt sensor 7 transmits the tilt data to the driller's control system in real time. The driller's control system sends a corresponding control signal to the tensioning device 1 based on the tilt data. If the tilt data is greater than the set value, the driller's control system sends a tightening control signal to the tensioning device 1, which tightens the tensioning device 1. The moving pulley 5 moves towards the bottom of the derrick 11 via the transmission device 3, and the second-level operating platform 12 slowly rotates towards the derrick 11. If the tilt data is less than the set value, the driller's control system sends a release control signal to the tensioning device 1, which releases the tensioning device 1. The moving pulley 5 moves towards the top of the derrick 11 via the transmission device 3, and the second-level operating platform 12 slowly rotates away from the derrick 11. If the tilt data is equal to the set value, the driller's control system sends a closing control signal to the tensioning device 1.

[0051] Step 6: The driller's control system sends a shut-off control signal to the clamping device 4.

[0052] Step 7: When the derrick 11 needs to be moved for transportation, the driller's control system sends an opening control signal to the clamping device 4.

[0053] Step 8: The driller's control system sends a tightening control signal to the tensioning device 1. The tensioning device 1 begins to tighten slowly, and the moving pulley 5 moves towards the bottom of the derrick 11 through the transmission device 3. The second-level operating platform 12 slowly rotates towards the derrick 11.

[0054] Step 9: When the tensioning device 1 reaches the set maximum tension, the driller's control system sends a shut-off control signal to the tensioning device 1.

[0055] Step 11: The driller's control system sends a shut-off control signal to the clamping device 4.

[0056] Step 12: The second section of the derrick 11 is retracted until it overlaps with the first section of the derrick 11.

[0057] Step 13: The first section of the derrick 11 is rotated horizontally and lowered until it is horizontal.

[0058] This invention provides an automatic tilt adjustment system and method for a two-level control panel in drilling and workover. The system and method are reliable and simple. Operators can perform adjustments independently within a safe area using a remote control panel, or centrally from the driller's cabin or drill box. When used in conjunction with a level detection system, this system and method can achieve precise leveling of the two-level control panel. It reduces repetitive leveling work caused by leveling issues on the two-level control panel, avoids safety hazards arising from leveling problems, reduces the workload of on-site workers, and improves the efficiency of equipment installation and commissioning. The automatic tilt adjustment system for the two-level control panel makes product control more integrated and intelligent, while also significantly enhancing the product's additional functions.

[0059] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
