[0042] Example 2

[0043] like Figure 7-8 As shown, on the basis of Example 1, it is further proposed that the outer surface of the outer shell 1 is detachably connected to a grouting pipe 5, the outer surface of the outer shell 1 is fixedly connected to a fixing frame 6, the outer surface of the fixing frame 6 is provided with a lifting hole 7, the spraying structure 4 includes a slurry outlet pipe 41 fixedly connected to the inner side of the outer shell 1, the inner side of the slurry outlet pipe 41 is slidably connected to a movable pipe 42, a reset spring 43 is connected between the cavity formed between the movable pipe 42 and the slurry outlet pipe 41, and the interior of the slurry outlet pipe 41 is connected to a vibration component 44.

[0044] The vibration assembly 44 includes a vibration tube 441 which is slidably connected to the inside of the movable tube 42, a sliding ring 442 is fixedly connected to the outer surface of the vibration tube 441, a fixing ring 443 is fixedly connected to the inner wall surface of the movable tube 42, a No. 2 push spring 444 is connected between the fixing ring 443 and the sliding ring 442, a vibration motor 445 is fixedly connected to the inside of the movable tube 42 through a bracket, a toggle plate 446 is fixedly connected to the output end of the vibration motor 445, and a convex ball 447 is fixedly connected to the outer surface of one end of the vibration tube 441.

[0045] The movable tube 42 slides along the length direction of the slurry outlet pipe 41, and the return spring 43 is used to push the movable tube 42 to move toward the inner side of the slurry outlet pipe 41. The return spring 43 is arranged along the length direction of the slurry outlet pipe 41, and the elastic ends of the return spring 43 are fixedly connected to the movable tube 42 and the slurry outlet pipe 41 respectively. The grouting pipe 5 is used to supply plugging slurry to the slurry outlet pipe 41.

[0046] The vibration tube 441 and the sliding ring 442 both slide along the length direction of the movable tube 42. The number of convex balls 447 is several groups and distributed in a ring array. The convex balls 447 are hemispherical structures. The vibration motor 445 drives the toggle plate 446 to rotate. The toggle plate 446 beats the convex balls 447 and the second push spring 444 cooperates to realize the vibration tube 441 moving back and forth along the length direction of the movable tube 42.

[0047] In this embodiment, when the anti-leakage liquid is poured into the cracks or holes in the leakage area, the action position of the spraying structure 4 can be automatically adjusted. At the same time, a certain vibration effect can be formed, so that the anti-leakage liquid is quickly distributed evenly in the leakage layer such as cracks or holes, thereby achieving a better plugging effect.

[0048] A method for using a drilling plugging device, the method comprising the following contents:

[0049] Step 1: lowering; using a lifting device to lift the outer shell 1 into the wellhead through the fixing frame 6 and the lifting hole 7, until the position of the outer shell 1 corresponds to the position of the crack in the well;

[0050] Step 2: Positioning and fine-tuning; lower the outer shell 1 to the position of the leakage layer in the well, and then drive the rotating shaft 31 to rotate in the positive direction through the main motor 39, so that the two sets of No. 1 movable frames 33 are close to each other, so that the surface of the roller 389 is in contact with the inner wall surface of the well. At this time, the main motor 39 stops driving the rotating shaft 31 to rotate, and the roller 389 is rotated by adjusting the operation of the motor 388, so that the action part of the shotcrete structure 4 corresponds to the leakage hole part. At this time, the horizontal angle is fine-tuned, and then the main motor 39 drives the rotating shaft 31 to rotate again until the surface of the positioning plate 36 is in contact with the inner wall of the well. At this time, the positioning is completed;

[0051] Step three: grouting and molding; supply plugging slurry to the slurry outlet pipe 41 through the grouting pipe 5, the plugging liquid enters the vibration component 44 from the movable pipe 42, generates a certain vibration through the vibration component 44, and injects the plugging liquid into the leakage layer while vibrating, and completes the plugging after solidification.

[0052] In summary, the working principle of the present invention is as follows:

[0053] When in use, when a leakage zone is found during drilling, the outer shell 1 is first hoisted into the wellhead through the fixing frame 6 and the hoisting hole 7 by a hoisting device until the position of the outer shell 1 corresponds to the position of the crack in the well;

[0054] The outer shell 1 is lowered to the leakage layer position in the well, and then the main motor 39 is used to drive the rotating shaft 31 to rotate in the forward direction. At this time, under the action of the threaded portion 32 and the guiding action of the slide groove 2, the two groups of No. 1 movable frames 33 are close to each other toward the middle of the rotating shaft 31. At this time, the two ends of the No. 2 movable frame 35 respectively rotate with the end plate 34 and the positioning plate 36, and the positioning plate 36 will gradually approach the inner wall of the well until the surface of the roller 389 is in contact with the inner wall surface of the well, and the positioning plate 36 is not in contact with the inner wall of the well. At this time, the main motor 39 stops driving the rotating shaft 31 to rotate, and drives the No. 2 gear 387 to rotate by adjusting the motor 388. The No. 2 gear 387 drives the No. 1 gear 386 to rotate, and the No. 1 gear 386 drives the rotating shaft 385 to rotate. The roller 389 is driven to rotate. Through the rotation of the roller 389 on the inner wall of the well, the action position of the shotcrete structure 4 corresponds to the position of the leaking hole. At this time, the regulating motor 388 stops running immediately, and the horizontal action angle of the shotcrete structure 4 is fine-tuned. Then, the main motor 39 drives the rotating shaft 31 to rotate again until the surface of the positioning plate 36 fits the inner wall of the well. Under the contraction of the No. 1 push spring 382, ​​the surface of the roller 389 continues to fit the inner wall of the well, and the positioning plate 36 can fit the inner wall surface of the well. At this time, the positioning is completed; and after the positioning plate 36 is separated from the inner wall of the well, the movable block 383, the movable column 384, and other structures thereon can be pushed to a distance away from one end of the fixed block 381 through the push action of the No. 1 push spring 382;

[0055] After positioning and fine-tuning are completed, plugging slurry is supplied to the slurry outlet pipe 41 through the grouting pipe 5. The plugging liquid enters the movable pipe 42, which will push the movable pipe 42 to move a distance toward the gap or hole. Then the plugging liquid enters the vibration tube 441 of the vibration assembly 44 from the movable pipe 42 and is directly injected into the hole or gap. In the process of injecting the plugging liquid, the toggle plate 446 is driven to rotate by the vibration motor 445. The toggle plate 446 continuously hits the convex ball 447, and the reverse pushing action of the No. 2 pushing spring 444 can make the vibration tube 441 vibrate to a certain extent. While vibrating, the plugging liquid is injected into the leakage layer, so that the plugging liquid can be quickly evenly distributed in the cracks or holes, and the plugging can be completed after solidification.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

A method for using the drilling plugging device according to any one of claims 1 to 9, characterized in that: The usage includes the following: Step 1: lowering; using a lifting device to lift the outer shell (1) into the wellhead through the fixing frame (6) and the lifting hole (7), until the position of the outer shell (1) corresponds to the position of the crack in the well; Step 2: Positioning and fine-tuning; the outer shell (1) is lowered to the position of the leakage layer in the well, and then the main motor (39) drives the rotating shaft (31) to rotate in the positive direction, so that the two groups of No. 1 movable frames (33) are close to each other, so that the surface of the roller (389) is in contact with the inner wall surface of the well. At this time, the main motor (39) stops driving the rotating shaft (31) to rotate, and the roller (389) is rotated by adjusting the operation of the motor (388), so that the action part of the shotcrete structure (4) corresponds to the leakage hole part. At this time, the horizontal angle is fine-tuned, and then the main motor (39) drives the rotating shaft (31) to rotate again until the surface of the positioning plate (36) is in contact with the inner wall of the well. At this time, the positioning is completed; Step 3: grouting and molding; supplying plugging slurry to the slurry outlet pipe (41) through the grouting pipe (5); the plugging liquid enters the vibration component (44) from the movable pipe (42); a certain vibration is generated through the vibration component (44); while vibrating, the plugging liquid is injected into the leakage layer; after solidification, the plugging is completed.
