Description

TECHNICAL FIELD

[0001] The utility model relates to a stuck tool technical field, concretely relates to a while drilling jar. BACKGROUND

[0002] For many different types of stuck drill pipe, the jar has developed so far, and there are many successful cases of stuck pipe. But for complex well conditions, the conventional jar is difficult to achieve the expected effect. For sand plug and gravel stuck drill pipe in the completion process, the conventional jar can only produce single one-way shock after being pulled or pressed, and a long time is needed for resetting and preparation before the second shock, so it is difficult to achieve the purpose of stuck pipe. For coiled tubing stuck drill pipe, the conventional jar is pulled up and pressed down many times during the stuck pipe process, which leads to fatigue failure of the coiled tubing and causes great economic loss.

[0003] After searching, a continuous while drilling jar (publication number: CN213478276U) is disclosed in the prior art. The document records "the middle part of the bottom of the bearing beam is fixedly installed with a moving guide rail, the middle part of the bottom of the moving guide rail is provided with a sleeve ring, the inner ring of the sleeve ring is fixedly connected with a spray head, the top of one side of the sleeve ring is fixedly connected with a water inlet pipe, the middle part of the top of the base is provided with a mounting bottom plate, the top of the mounting bottom plate is fixedly connected with a support column, the inner wall of the bottom of the mounting bottom plate is fixedly connected with a square column, the top of the support column is provided with a connecting rod, the top end of the connecting rod is fixedly connected with an arc-shaped supporting plate, the middle part of the connecting rod is sleeved with a threaded sleeve, and the bottom of the threaded sleeve is fixedly connected with a connecting ring." The jar clamps and fixes the while drilling jar by the hydraulic push rod pushing the buffer pad, drives the sleeve ring to move outside the while drilling jar by the moving guide rail, removes the dirt attached to the while drilling jar by the flushing of the spray head, and thus prolongs the service life of the while drilling jar and realizes unlimited use of the while drilling jar. However, the moving range of the sleeve ring in the jar is limited by the supporting components such as the mounting bottom plate and the arc-shaped supporting plate, which leads to the fact that the spray head in the sleeve ring cannot comprehensively clean the while drilling jar from beginning to end, and only most areas can be cleaned, while the areas at both ends of the while drilling jar are difficult to clean and can only be cleaned by workers again, thereby reducing the cleaning efficiency of the while drilling jar.

[0019] Reference Figures 1 to 4As shown, this utility model provides a drilling oscillator, including: a base 1, the surface of which is movably connected to the oscillator body 5 via hydraulic push rods 2 and electric push rods 20; a retaining wall 3, a fixing frame 6, and a main motor 13 are fixedly connected to the upper surface of the base 1 respectively; hydraulic push rods 2 are symmetrically connected to both ends of the retaining wall 3; a drive roller 7 is movably connected to the upper end of the inner cavity of the fixing frame 6 via a sealed bearing; the output shaft of the main motor 13 meshes with a transmission rod 15 via a bevel gear, and both ends of the transmission rod 15 are movably connected to a transmission groove 9 opened in the fixing frame 6 via sealed bearings. Inside, the transmission rod 15 and the drive roller 7 are respectively fixedly connected to the drive wheel 11 and the driven wheel 8 at one end in the transmission groove 9. The drive wheel 11 is connected to the driven wheel 8 through the toothed belt 10. At the same time, the upper end of the enclosure 3 is opened with a moving groove 21. The upper surface of the enclosure 3 is fixedly connected to the electric push rod 20. The telescopic rod of the electric push rod 20 passes through the through hole and is fixedly connected to the moving plate 19 in the moving groove 21. The lower surface of the moving plate 19 away from the electric push rod 20 is fixedly connected to the fastening frame 23. The lower surface of the fastening frame 23 is movably connected to the driven roller 16 through the sealed bearing.

[0020] In this embodiment, the main body 5 of the drilling shock generator is first placed on the upper surface of the active roller 7. Then, the hydraulic push rod 2 is activated, and its extension rod abuts against both ends of the main body 5 via the limiting plate 4, achieving initial positioning of the main body 5. Next, the electric push rod 20 is activated, and its extension rod pushes the moving plate 19 downwards. The moving plate 19 then drives the fixedly connected fastening frame 23 downwards synchronously. Subsequently, the driven roller 16, movably connected within the fastening frame 23, abuts against the upper surface of the main body 5, thus cooperating with the active roller 7 to complete secondary positioning of the main body 5. Afterwards, the main motor 13 is activated, and its output shaft, via a cone... The gear drives the transmission rod 15 to rotate, and the driving wheel 11, which is fixedly connected to both ends of the rotating rod, can drive the corresponding driven wheel 8 to rotate through the meshing toothed belt 10. Then, the driven wheel 8 can drive the corresponding driving roller 7 to rotate, so that the driving roller 7 can drive the drilling oscillator body 5 to rotate at a uniform speed. When the switch of the external high-pressure water source (not shown in the figure) is turned on, the liquid from the external high-pressure water source can be injected into the diversion box 24 through the infusion pipe. The liquid in the diversion box 24 can be sprayed onto the surface of the drilling oscillator body 5 through the high-pressure nozzle, thereby achieving a comprehensive cleaning of the drilling oscillator body 5, improving cleaning efficiency, reducing the labor intensity of workers, and helping to extend the service life of the drilling oscillator body 5.

The telescopic rods of the hydraulic push rods 2 are movably connected to the limiting plate 4 through the sealed bearing. The limiting plate 4 has a square structure, and the movable groove 21 opened on the surface of the enclosure 3 has a rectangular structure.

[0022] In this embodiment, asFigure 1 and Figure 3 The setting of the limiting plate 4 can not only help to clamp and position the shock absorber body 5, but also ensure that the shock absorber body 5 can rotate normally, thereby facilitating the improvement of the cleaning effect of the shock absorber body 5 during drilling.

[0023] As a preferred embodiment, main slide grooves 22 are symmetrically opened on both sides of the movable groove 21. Both sets of main slide grooves 22 are elongated structures, and the movable plate 19 is rectangular. The size of the movable plate 19 is adapted to the movable groove 21, and the positions of the two sides of the movable plate 19 relative to the main slide grooves 22 are connected to the main sliders, which are square structures.

[0024] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The dimensions of the main slide 22 and the main slider are matched, which helps to enhance the stability of the moving plate 19 when it moves in the moving groove 21. At the same time, the dimensions of the moving plate 19 and the moving groove 21 are matched, which helps to reduce the probability of the moving plate 19 shaking during movement.

At the same time, the fastening frame 23 fixedly connected to the lower surface of the movable plate 19 has a U-shaped structure.

[0026] In this embodiment, as Figure 3 , Figure 4 and Figure 5 The auxiliary plate 17 and the reinforcing plate 18 can help improve the overall structural strength of the moving plate 19, thereby reducing the probability of the moving plate 19 bending and deforming unexpectedly when it comes into contact with the shock absorber body 5 by the driven roller 16.

[0027] As a preferred embodiment, the fixed frame 6 has a square cylindrical structure. Two sets of driving rollers 7 are symmetrically connected to the upper end of the inner cavity of the fixed frame 6.

[0028] In this embodiment, as Figure 1 and Figure 2Anti-slip sleeves are fixedly connected to the surfaces of the active roller 7 and the driven roller 16. The anti-slip sleeves are made of soft rubber material, which can help enhance the clamping and rotation effect of the active roller 7 and the driven roller 16 on the main body 5 of the drilling oscillator. At the same time, the cooperation of the toothed belt 10, the active wheel 11 and the driven wheel 8 enables the active roller 7, which is movably connected in the fixed frame 6, to rotate synchronously, thereby improving the stability of the main body 5 of the oscillator when it rotates.

[0030] In this embodiment, as Figure 1 and Figure 3 The baffle plate 12 and the side baffle plate 14 allow the bevel gears that mesh between the main motor 13 and the transmission rod 15 to be in a relatively enclosed environment, thereby preventing external debris from getting stuck in the tooth grooves of the bevel gears and reducing the probability of bevel gear transmission failure. At the same time, the main motor 13 is equipped with a waterproof shell.

[0031] In a preferred embodiment, the inner side of the enclosure 3 is fixedly connected to the diversion box 24 relative to the position of the shock absorber body 5 by a snap fastener. The diversion box 24 has a long strip structure and a cross-section with a U-shape. Multiple high-pressure nozzles are fixedly connected to the surface of the diversion box 24 at equal intervals along the length direction. At the same time, the surface of the high-pressure nozzles is screwed with sealing caps.

[0032] In this embodiment, as Figure 2 and Figure 3 The fixing method of the diversion box 24 allows the position of the diversion box 24 to be easily adjusted according to actual needs. At the same time, the sealing cap of the high-pressure nozzle screwed on prevents the unused high-pressure nozzle on the surface of the diversion box 24 from spraying liquid, thus helping to reduce resource waste.
