Technical Field
[0001] The invention relates to the technical field of petroleum drill pipe manufacturing, in particular to a petroleum integral weighted drill pipe and manufacturing equipment thereof. Background Art
[0002] Oil weighted drill pipe is a specially designed drill pipe, and its structure and material are different from ordinary drill pipe. Weighted drill pipe usually has thicker wall thickness and greater weight to enhance its load-bearing capacity and stability. In addition, the connection part of the weighted drill pipe is also specially designed to ensure a tight connection with the drill pipe and other drilling tools. Oil weighted drill pipe is mainly used in oil drilling operations, especially in situations where it is necessary to increase drilling pressure, reduce the contact area between the drill string and the well wall, and reduce the outer diameter wear rate.
[0003] The pre-processing stage of oil drill pipe mainly includes raw material preparation, rough joint processing and other processes. After these processes are completed, the drill pipe may bend or twist due to external forces, temperature changes and other factors during the processing. In order to ensure the straightness of the drill pipe and the quality of subsequent processing, the straightening process becomes a necessary link.
[0004] The diameter of oil weighted drill pipe is not fixed, but is selected according to specific drilling needs and operating conditions. There is a certain standard range of diameter specifications, but it also varies depending on different manufacturers and application scenarios. The diameter specifications of weighted drill pipe are usually expressed in inches. Among the common specifications, the diameter of weighted drill pipe may be 3 inches, 3.5 inches, 4 inches, etc. The selection of these specifications depends on the specific requirements of the drilling operation, such as well depth, formation conditions, drilling pressure requirements, etc.
[0005] Therefore, during the straightening operation, the drill pipe needs to be rotated and adjusted after it is fixed, so as to conduct a comprehensive inspection of the drill pipe and straighten the area to be straightened. However, the existing processing and manufacturing equipment cannot adapt to the fixation of oil weighted drill pipes with different diameters, so it is necessary to add or replace related equipment for processing operations, which greatly increases the production cost. Summary of the invention
[0006] In order to solve the technical problem proposed in the background technology that petroleum weighted drill pipe is prone to bending during its manufacturing process, it is necessary to use straightening equipment to straighten it, but the existing manufacturing equipment cannot quickly adapt to the clamping and fixing of drill pipes of different diameters, so it is necessary to replace related equipment, thereby increasing costs and reducing efficiency. The present invention provides a petroleum integral weighted drill pipe and its manufacturing equipment.
[0007] The present invention is implemented by the following technical scheme: an integrally weighted petroleum drill pipe and its manufacturing equipment, comprising a base, horizontal grooves are provided on both sides of the base, a movable frame is horizontally slidably connected in the horizontal groove, a hydraulic rod 1 is fixedly connected to the top of the movable frame, a straightening adaptation mechanism is connected to the bottom end of the telescopic end of the hydraulic rod 1, support rods are symmetrically fixedly connected to both sides of the middle of the base, a horizontal plate is fixedly connected to the middle of the base, a sliding seat is horizontally slidably connected to the horizontal plate, cross plates are symmetrically fixedly connected to both sides of the sliding seat, and the other ends of the two cross plates are fixedly connected to the inner wall of the movable frame, a supporting adaptation mechanism is connected to the top of the sliding seat, a hydraulic rod 2 is symmetrically fixedly connected to one side of the base, the outer end of the hydraulic rod 2 is fixedly connected to the support seat, and a tightening adaptation mechanism is provided in the middle of the top of the support seat.

[0009] Through the above technical scheme, the laser ranging sensor can be used to adaptively adjust the center of rods of different diameters, and the inner wall of the rod can be adaptively tightened under the action of the tightening adaptation mechanism, and stable support and rotation can be provided for subsequent detection. The support adaptation mechanism will quickly adapt to the diameter of the rod in coordination with the straightening adaptation mechanism, and can quickly straighten the scanned rod under the action of the displacement motor.
[0010] As a further improvement of the above scheme, the supporting adaptation mechanism includes four hydraulic rods symmetrically fixedly connected to both sides of the sliding seat, the middle parts of the top ends of the two hydraulic rods are vertically slidably connected with telescopic rods, the top ends of the two telescopic rods are fixedly connected with cross blocks, the middle parts of the top ends of the two cross blocks are fixedly connected with cross bars, the interiors of the two cross blocks are hollow, and the interiors of the two cross blocks are provided with inner sliding bars, and the two inner sliding bars are relatively horizontally slidably connected with inner sliding blocks.
[0011] Through the above technical scheme, the horizontal sliding connection state of the cross block and the inner sliding block is utilized to ensure that as the diameter of the rod body changes, the rotating sleeve plate of the external horizontal sliding connection can always be kept in a vertical state to meet the needs of synchronous adjustment of the upper sliding plate. Among them, the hydraulic rod four can reduce the support control of the telescopic rod during the initial adaptation support stage, and after completing the initial clamping of the rod body, it can achieve stable control of the telescopic rod to avoid instability during the straightening operation.

[0018] Through the above technical scheme, the spring is used to realize elastic support for the inner slide plate. On the one hand, it ensures that the inner slide plate can always slide vertically with the upper slide plate. On the other hand, as the straightening downward operation proceeds, the inner slide plate will contact with the inner side of the upper slide plate and push the spring to contract without affecting the normal operation of the straightening operation.

[0021] As a further improvement of the above solution, the top ends of the two support rods are semicircular rings with a diameter of 4 inches.
[0022] Through the above technical solution, 4 inches is the largest diameter among the commonly used rod diameters, which can well adapt to the support of common rods.

[0025] As a further improvement of the above solution, a baffle is provided at the connection between the telescopic outer rod and the telescopic inner rod, and the baffle blocks one end of the telescopic inner rod away from the rotating rod.
[0026] The above technical solution can prevent the telescopic outer rod from falling off due to excessive displacement of the telescopic inner rod.

[0029] (ii) The linkage between the straightening adaptation mechanism and the supporting adaptation mechanism of the present invention can always ensure the relative vertical sliding connection between the upper slide plate and the inner slide plate, and can rely on the stable support of the hydraulic rod four to further ensure that the equipment can still perform a stable clamping operation on the rod body during the straightening operation, thereby ensuring the supporting and fixing effect of the equipment.
[0030] (III) The present invention utilizes the cooperation of the displacement motor, the support adaptation mechanism and the straightening adaptation mechanism to perform reciprocating displacement and synchronous scanning in the base, analyzes the scanned data, and cooperates with the rotation of the motor to achieve comprehensive correction of the rod body, effectively improving the correction efficiency and effect.

[0048] The implementation principle of an integrally weighted oil drill pipe and its manufacturing equipment in the embodiment of the present application is as follows:
[0049] After these processes are completed, the processed rod body 7 is transported to the top of the two groups of support rods 6 by means of conveying equipment, the center of the rod body 7 is positioned by means of a laser distance sensor, and the hydraulic rod three 10 is driven to adjust the height as needed, so that the tight adaptation mechanism is at the center of the rod body 7, and then the hydraulic rod two 8 is started to shrink and send the tight adaptation mechanism into the rod body 7, the motor two 15 is started to use the rotating shaft 24 and the gear two 25 to fix, so that the gear two 25 rotates and the gear two 25 is meshed and connected with multiple gears one 20, so that multiple rotating drums 19 rotate synchronously, at this time, multiple threaded rods 21 will be threadedly connected with the rotating drum 19, and the telescopic tube body 23 connected with the limit position on both sides can be synchronously displaced and expanded outward, and finally the outer walls of multiple abutment plates 22 are tightly pressed against the inner wall of the rod body 7.

[0051] Example 2: Combination Figure 2 , Figure 6 and Figure 7 Based on Example 1, this embodiment is further improved in that:
[0052] The supporting adaptation mechanism includes hydraulic rods 29 symmetrically fixedly connected to both sides of the sliding seat 5, and the middle parts of the top ends of the two hydraulic rods 29 are vertically slidably connected with telescopic rods 30, and the top ends of the two telescopic rods 30 are fixedly connected with cross blocks 31, and the middle parts of the top ends of the two cross blocks 31 are fixedly connected with cross bars, the interiors of the two cross blocks 31 are hollow, and the interiors of the two cross blocks 31 are provided with inner slide bars 32, and the two inner slide bars 32 are relatively horizontally slidably connected with inner sliders 33, wherein the telescopic rods 30 will follow when adapting to the diameter of the rod body 7, and when the clamping operation is completed, the hydraulic rods 29 will keep the telescopic rods 30 in a locked state in height to avoid displacement changes of the upper supporting arc plate 40 during the straightening operation.
[0053] The other ends of the two inner sliders 33 are rotatably connected to the lower supporting arc plate 34 , and the inner sliders 33 are arranged in the middle of the top end of the lower supporting arc plate 34 , and the bottom ends of the two lower supporting arc plates 34 are rotatably connected to the top of the sliding seat 5 .
[0054] The outer sides of the top ends of the two lower supporting arc plates 34 are rotatably connected with rotating sleeve plates 35. The outer sides of the two rotating sleeve plates 35 are relatively horizontally slidably connected with the cross block 31. The top ends of the two rotating sleeve plates 35 are connected with the straightening adaptation mechanism.
[0055] The implementation principle of an integrally weighted oil drill pipe and its manufacturing equipment in the embodiment of the present application is as follows:
[0056] When the rod body 7 is transported to the middle of the support rod 6 and the two rotating sleeves 35, when the diameter of the rod body 7 is 4 inches, the lower supporting arc plate 34 does not need to change and can stably clamp and fix the rod body 7. When the diameter of the rod body 7 is reduced, the two sets of lower supporting arc plates 34 will achieve synchronous diameter clamping changes under the connection between the straightening adaptation mechanism and the support plate 11, so as to quickly realize that when the straightening extrusion action is performed, the contact between the bottom end and the rod body 7 can maintain its own stability to ensure the straightening effect.
[0057] Example 3: Combination Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown in FIG. 3 of the hydraulic rod 10, the present embodiment is further improved on the basis of the embodiments 1 and 2 in that:
[0058] The straightening adaptation mechanism includes a top plate 41, which is fixedly connected to the bottom of the telescopic end of the movable frame 2. The bottom end of the top plate 41 is symmetrically rotatably connected to the upper supporting arc plate 40. The bottom ends of the two upper supporting arc plates 40 are both rotatably connected to the upper slide plates 39. The bottom ends of the two upper slide plates 39 are both convex-shaped openings, and the top ends of the convex characters are set outward. The bottom ends of the two upper slide plates 39 are both vertically slidably connected to the inner slide plate 38, and the bottom ends of the inner slide plates 38 are both slidably connected to the lower slide plate 36.
[0059] A spring 37 is elastically connected between the inner bottom end of the lower slide plate 36 and the middle of the inner slide plate 38 , and the bottom ends of the two lower slide plates 36 are fixedly connected to the rotating sleeve plate 35 .
[0060] The two upper slides 39 are fixedly connected to the telescopic outer rod 28 on the same side, and the two telescopic outer rods 28 are relatively horizontally slidably connected to the telescopic inner rod 27 on the side away from the upper slide 39. The outer walls of the two telescopic inner rods 27 are horizontally slidably connected to sliding sleeve blocks, and the bottom ends of the two sliding sleeve blocks are elastically connected to strong springs, and the bottom ends of the two strong springs are fixedly connected to rotating rods 26. The two rotating rods 26 are rotatably connected to both sides of the support plate 11. Specifically, when the diameter of the rod body 7 is adapted, the telescopic outer rod 28 can be pulled under the support of the strong spring, and the clamping diameter change adaptation can be achieved through the fixed connection state of the telescopic outer rod 28 and the upper slide 39, and because the upper supporting arc plate 40 is rotatably connected to the upper slide 39, the movement trajectory of the telescopic outer rod 28 is arc-shaped, so that it can adapt to changes under the rotation connection of the rotating rod 26.
[0061] A baffle is provided at the connection between the telescopic outer rod 28 and the telescopic inner rod 27 , and the baffle blocks one end of the telescopic inner rod 27 away from the rotating rod 26 .
[0062] The implementation principle of an integrally weighted oil drill pipe and its manufacturing equipment in the embodiment of the present application is as follows:
[0063] After the laser ranging sensor drives the hydraulic rod three 10 to drive the support plate 11 to perform a vertical displacement change, the two upper slide plates 39 will drive the entire upper slide plate 39 to move vertically downward under the connection between the telescopic inner rod 27 and the telescopic outer rod 28, and the upper slide plate 39 will drive the two upper support arc plates 40 to flip inward around the rotation connection between the top end and the top plate 41 by utilizing the rotation connection between the upper slide plate 39 and the upper support arc plate 41. At this time, as the upper slide plate 39 moves inward inward, the inner slide plate 38 will be synchronously driven to move inward by utilizing the rotation connection between the rotating sleeve plate 35 and the lower support arc plate 34, and the inward displacement of the upper support arc plate 40 is consistent with that of the lower support arc plate 34, and matches the current diameter of the rod body 7. As the displacement of the rotating sleeve plate 35 changes, the sliding connection between the rotating sleeve plate 35 and the cross block 31 will drive the two telescopic rods 30 to adapt to the change, thereby achieving auxiliary support.
[0064] After the information is confirmed, the entire movable frame 2 and the sliding seat 5 are moved to the required position by using the displacement motor, and then the motor 13 is used to rotate the rod body 7 to the area to be straightened, and the hydraulic rod 3 is started to drive the top plate 41 to be pressed vertically down to the top of the outer wall of the rod body 7. As the top plate 41 moves downward, the two upper slides 39 will move vertically downward with the inner slide 38, and complete the straightening of a single area of the rod body 7. When other areas still need straightening operations, repeat the above operations, and after completing the straightening operation, perform a comprehensive scan of the rod body 7 again to ensure the straightening effect of the rod body 7.
