[0002] When performing well repair operations in oil fields, it is necessary to build a drilling platform on the ground. The drilling platform provides a stable working platform for the well repair operations, so that the well repair operations can be carried out in a safe and stable environment. The unbuckling devices on the overhaul operation automation system mainly include two forms: iron roughnecks and automatic hydraulic pliers. The two existing forms have problems such as complex structure and large size to a certain extent. Usually, the installation connection with the drilling platform mainly adopts flange bolt connection, insert barrel and other methods. The transportation and installation process requires trucks, cranes, special bases and multiple people to cooperate, resulting in high transportation costs, cumbersome transportation and installation, and a long time.

[0003] A patent with publication number CN112983313B discloses oilfield well repair operation equipment, wherein the main drilling platform includes a drilling platform panel, on which an avoidance hole is provided; a lifting device is installed below the drilling platform panel, the lifting device includes a platform base, a guide column group, a lifting platform and a lifting drive mechanism, the guide column group is fixedly connected between the platform base and the drilling platform panel; the lifting platform is slidably connected to the guide column group; the lifting drive mechanism is transmission-connected to the lifting platform, and the lifting drive mechanism can drive the lifting platform to rise and fall along the guide column group. Since the upper and lower buckle devices are installed on the lifting platform, the upper and lower buckle devices can be extended out of the avoidance hole when in use for easy use, and can be retracted from the avoidance hole when not in use for easy storage and transportation; no on-site installation is required when in use, thus saving installation time.

[0004] In the above-mentioned prior art, when performing well repair operations, after a section of drill pipe is drilled into the ground, it is necessary to assemble a new section of drill pipe on the upper end of the drill pipe drilled into the ground, and then rotate the drill pipe again to make the drill pipe penetrate into the ground until it reaches the standard construction depth.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figure 1-4 As shown, a hydraulic well repairing drilling platform described in an embodiment of the present invention includes a drilling platform panel 1, and a rectangular plate 13 is fixedly connected to the four corners of the lower end of the drilling platform panel 1 through a cylindrical support column 12. A first rectangular hole 11 is provided in the middle of the drilling platform panel 1, and a second rectangular hole 131 is provided in the middle of the rectangular plate 13. A first slide rail 2 is fixedly connected to one side of the first rectangular hole 11, and the lower end of the first slide rail 2 is fixed to the rectangular plate 13. A slide 21 is slidably provided on one side of the first slide rail 2, and a clamping assembly is installed on one side of the slide 21. A hydraulic system for driving the clamping assembly to move is provided at the upper end of the drilling platform panel 1, and the clamping assembly includes a U-shaped block 3 provided on one side of the slide 21, and two first arc blocks 33 are rotatably provided on one side of the U-shaped block 3, and a second arc block 331 is rotatably provided on one side of the first arc block 33, and a rotating assembly is rotatably provided on the upper end of the first arc block 33, and the rotating assembly includes arc plates 34 respectively fixed to the upper ends of the first arc blocks 33, and a fourth arc block 344 is rotatably provided inside the arc plate 34.

[0023] When the drill rig is used for well repair, the U-shaped block 3 is installed on one side of the slide 21, and the drill pipe is then placed between the two first arc blocks 33, and the two first arc blocks 33 are driven to rotate toward the side close to the drill pipe at the same time until the second arc block 331 aligns the drill pipe. The drill rod is clamped, and then the second arc block 331 is driven to rotate to drive the middle drill rod to rotate. At the same time, the slide 21 is driven by the hydraulic system to slide downward along the first slide rail 2. The slide 21 drives the drill rod clamped in the middle to move downward through the first arc block 33. At the same time, the drill rod rotates to enable the drill rod to drill into the ground. When the drill rod needs to be assembled, the two first arc blocks 33 are driven to rotate to the side away from the drill rod. Then, the drill rod is vertically hoisted between the two arc plates 34 using a crane. Then, the first arc block 33 is driven to rotate to the side close to the drill rod again. The first arc block 33 drives the arc plate 34 to clamp the lower end of the hoisted drill rod. The arc plate 34 drives the fourth arc block 344 to clamp the hoisted drill rod. Then, the fourth arc block 344 is driven to rotate and be installed on the upper end of the drill rod drilled into the ground. No manual installation is required, which solves the risk of tilting or falling of the drill rod in a hoisting state when the drill rod is manually installed, which poses a certain safety hazard.

[0024] like Figure 4 As shown, a plurality of elastic components are respectively provided on one side of the interior of the second arc block 331 and the fourth arc block 344, and the elastic components include a first rectangular block 332 fixed at both ends of one side of the second arc block 331, and a second rectangular block 334 is slidably provided inside one side of the first rectangular block 332, and the second rectangular block 334 is fixed to one side of the interior of the first rectangular block 332 through a first spring 333.

[0025] Specifically, when the first arc block 33 is driven to move toward the drill rod side, the second arc blocks 331 on both sides respectively drive several second rectangular blocks 334 to be close to the side wall of the drill rod, so that the second rectangular blocks 334 slide toward the inside of the first rectangular block 332 and squeeze the first spring 333 to prevent excessive squeezing of the drill rod.

[0026] like Figure 4As shown, a third arc block 343 is slidably provided on one side of the interior of the arc plate 34, and the fourth arc block 344 can rotate on one side of the interior of the third arc block 343. A cylindrical bar 3431 is fixedly connected to the upper end of the third arc block 343. The cylindrical bar 3431 slides through the upper end of the arc plate 34, and the upper end of the cylindrical bar 3431 is fixedly connected to the arc plate 34 through a second spring 3432.

[0027] Specifically, when the fourth arc block 344 clamps the drill rod and rotates, the fourth arc block 344 drives the third arc block 343 to move downward, and at the same time the third arc block 343 drives the cylindrical bar 3431 to move downward and stretch the second spring 3432 to install the two sections of the drill rod together. When the drill rod is assembled, the slide 21 is driven to slide upward on one side of the first slide rail 2, and then the upper end of the drill rod is clamped, and the assembled drill rod is drilled into the ground again until it reaches a suitable depth.

[0028] like Figure 5 As shown, a third rectangular hole 341 is respectively provided in the middle of the arc plate 34, a fourth rectangular hole 3433 is respectively provided in the middle of the third arc block 343, and a plurality of teeth 3441 are respectively provided on the side of the fourth arc block 344 close to the third arc block 343, and the teeth 3441 are respectively meshed with gears 345, and the gears 345 respectively pass through the third rectangular hole 341 and the fourth rectangular hole 3433.

[0029] Specifically, when it is necessary to drive the fourth arc block 344 to drive the drill rod to rotate, the driving gear 345 rotates, and the gear 345 drives the fourth arc blocks 344 on both sides to rotate in the third arc block 343 respectively through the teeth 3441. The fourth arc block 344 can drive the middle drill rod to rotate, so that the two sections of drill rod are installed together.

[0030] like Figure 5 As shown, the two sides of the gear 345 are rotatably connected with fixing bars 3451 through pins, and the fixing bars 3451 are fixedly connected with U-shaped plates 3452. The two ends of the outer side of the arc plate 34 are fixedly connected with second slide rails 3453, and the U-shaped plates 3452 can slide in the second slide rails 3453.

[0031] Specifically, when the driving gear 345 rotates and drives the fourth arc block 344 to rotate, when the fourth arc block 344 drives the drill rod at the upper end to rotate, the upper drill rod rotates and moves a distance to the lower end at the same time, and is assembled with the drill rod drilled into the ground. At this time, when the fourth arc block 344 moves downward, it drives the third arc block 343 to slide downward along one side of the arc plate 34. At this time, the gear 345 drives the U-shaped plate 3452 to move downward in the second slide rail 3453 through the fixing bar 3451, so that the gear 345 always follows the movement of the fourth arc block 344.

[0032] like Figure 3As shown, a first cylindrical rod 32 is fixedly connected to the middle of the U-shaped block 3, and the first arc block 33 can rotate outside the first cylindrical rod 32. Electric telescopic rods 35 are rotatably connected to both sides of the U-shaped block 3, and the output ends of the electric telescopic rods 35 are rotatably connected to the first arc block 33.

[0033] Specifically, when the drill rod needs to be clamped, the electric telescopic rod 35 is driven to extend to drive the two first arc blocks 33 to approach each other until the two first arc blocks 33 are close to each other to clamp the drill rod in the middle.

[0034] like Figure 2 As shown, first fixing blocks 22 are fixedly connected to both ends of one side of the slide 21 , bolts are installed between the two first fixing blocks 22 , and a first circular hole 31 is provided in the middle of the U-shaped block 3 .

[0035] Specifically, the first circular hole 31 provided in the middle of the U-shaped block 3 can be installed in the middle of the two first fixed blocks 22 by bolts, and installed on one side of the slide 21 through the first fixed block 22. The slide 21 can drive the clamping assembly provided on one side of the U-shaped block 3 to drive the drill rod to move downward, so that the drill rod can drill into the ground.

[0036] like Figure 1 As shown, crawlers 132 are respectively installed on both sides of the lower end of the rectangular plate 13, and support rods 14 are respectively fixed to the four corners of the drilling platform panel 1.

[0037] Specifically, when performing well repair work, the lower ends of the support rods 14 provided around the drilling platform panel 1 are in a state of being tilted outward, which can keep the drilling platform panel 1 stable. When the drilling platform needs to be moved, the driving track 132 is rotated to drive the upper drilling platform panel 1 to move, without the need to disassemble and rebuild the drilling platform.

[0038] Embodiment 2 like Figure 6 As shown, compared with Example 1, another embodiment of the present invention is: a support assembly is provided at the upper end of the drilling floor panel 1, and the support assembly includes two arc-shaped clamping plates 4 respectively located at the upper ends of the arc-shaped plates 34, and one side of the arc-shaped clamping plates 4 is rotatably connected to a second cylindrical rod 42, and the second cylindrical rod 42 is fixedly connected to one side of the inside of the cylinder 422 through a third spring 421, and the second cylindrical rod 42 can slide inside the cylinder 422, and the cylinder 422 is rotatably connected to the drilling floor panel 1 through a third fixing block 43.

[0039] Specifically, when installing the drill rod, it is necessary to keep the drill rod lifted at the upper end in a vertical alignment with the drill rod drilled into the ground. Since the upper drill rod is generally lifted by a crane, it may shake and the upper drill rod cannot be kept still. It is troublesome to align it with the drill rod drilled into the ground during installation, and it is necessary to constantly correct the position of the upper drill rod. Two arc-shaped clamping plates 4 are provided on the upper end of the drilling platform panel 1. The lifted drill rod is placed between the two arc-shaped clamping plates 4. The arc-shaped clamping plates 4 are supported by the second cylindrical rod 42 and the cylinder 422. The cylinder 422 is connected to the third fixed block 43 through a torsion spring. The cylinder 422 drives the two arc-shaped clamping plates 4 to approach the middle at the same time through the second cylindrical rod 42, so that the arc-shaped clamping plates 4 are close to the surface of the drill rod, and the lifted drill rod is clamped by the arc-shaped clamping plates 4 to keep the lifted drill rod still, which is convenient for installing the drill rod.

[0040] like Figure 6 As shown, the upper ends of the arc-shaped clamping plates 4 are respectively fixedly connected with conical arc-shaped plates 41 .

[0041] Specifically, when the drill rod needs to be assembled, a new drill rod needs to be installed on the upper end of the drill rod drilled into the ground, and the new drill rod needs to be hoisted and placed between the two arc-shaped clamping plates 4 to be aligned with the drill rod drilled into the ground. Since the two arc-shaped clamping plates 4 are always in a state of being close to each other, in order to keep the drill rod in a centered state, conical arc-shaped plates 41 are respectively provided at the upper ends of the arc-shaped clamping plates 4. The upper ends of the conical arc-shaped plates 41 have a larger diameter than the lower ends, which facilitates the lower end of the hoisted drill rod to enter between the two arc-shaped clamping plates 4.

[0042] Working principle: by driving the crawler 132 to rotate, the drilling platform panel 1 is driven to move to the upper end of the position where the well repair operation is required. The lower ends of the support rods 14 provided around the drilling platform panel 1 are respectively in a state of tilting outwards, which can keep the drilling platform panel 1 stable. Then, the U-shaped block 3 is installed between the two first fixed blocks 22 through the first circular hole 31 provided in the middle by bolts, and is installed on one side of the slide 21 through the first fixed block 22. Then, the drill rod is vertically lifted between the two first arc blocks 33 by a crane, and the two first arc blocks 33 are driven to approach each other by driving the electric telescopic rod 35 to extend, until the two first arc blocks 33 are close to each other to clamp the drill rod in the middle, and then the second arc block 331 is driven to rotate to drive the drill rod in the middle to rotate, and at the same time, the slide 21 slides downward along the first slide rail 2, and the slide 21 drives the drill rod clamped in the middle to move downward through the first arc block 33. At the same time, the drill rod rotates, so that the drill rod can drill into the ground; When the drill rod needs to be assembled, a new drill rod needs to be installed on the upper end of the drill rod drilled into the ground. The new drill rod needs to be hoisted and placed between the two arc-shaped clamping plates 4 to align with the drill rod drilled into the ground. Since the two arc-shaped clamping plates 4 are always in a state of being close to each other, in order to keep the drill rod in a centered state, a conical arc-shaped plate 41 is provided at the upper end of the arc-shaped clamping plate 4. The upper end of the conical arc-shaped plate 41 has a larger diameter than the lower end, which is convenient for the lower end of the hoisted drill rod to enter The suspended drill rod is placed between the two arc-shaped clamping plates 4. The arc-shaped clamping plates 4 are supported by the second cylindrical rod 42 and the cylinder 422. The cylinder 422 is connected to the third fixing block 43 through a torsion spring. The cylinder 422 drives the two arc-shaped clamping plates 4 to approach the middle at the same time through the second cylindrical rod 42, so that the arc-shaped clamping plates 4 are close to the surface of the drill rod. The suspended drill rod is clamped by the arc-shaped clamping plates 4, so that the suspended drill rod remains stationary, which is convenient for installing the drill rod. Then the driving gear 345 rotates, and the gear 345 drives the fourth arc blocks 344 on both sides to rotate in the third arc block 343 respectively through the teeth 3441. The fourth arc block 344 can drive the drill rod in the middle to rotate, so that the two sections of the drill rod are installed together. When the driving gear 345 rotates to drive the fourth arc block 344 to rotate, when the fourth arc block 344 drives the drill rod at the upper end to rotate, the upper end of the drill rod rotates and moves a distance to the lower end at the same time, and is assembled with the drill rod drilled into the ground. At this time, when the fourth arc block 344 moves downward, it drives the third arc block 343 to slide downward along one side of the arc plate 34. At this time, the gear 345 drives the U-shaped plate 3452 to move downward in the second slide rail 3453 through the fixing bar 3451, so that the gear 345 always follows the movement of the fourth arc block 344; When the fourth arc block 344 clamps the drill rod and rotates, the fourth arc block 344 drives the third arc block 343 to move downward. At the same time, the third arc block 343 drives the cylindrical bar 3431 to move downward and stretches the second spring 3432 to install the two sections of the drill rod together. When the drill rod is assembled, the slide 21 is driven to slide upward on one side of the first slide rail 2, and then the upper end of the drill rod is clamped to drill the assembled drill rod into the ground again until it reaches a suitable depth.
