in the figure: the device comprises a body 1, a circulation hole 2, a hoop spring 3, a jaw shaft 4, a jaw 5, a limiting ring 6, a jaw groove 7 and a clamping groove 8.
Detailed Description
The present invention will be described below based on examples, but it should be noted that the present invention is not limited to these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. However, for parts not described in detail, those skilled in the art can fully understand the present invention.
Furthermore, those skilled in the art will appreciate that the drawings are provided for purposes of illustrating the objects, features, and advantages of the invention and are not necessarily drawn to scale.
Also, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, the meaning of "includes but is not limited to".
FIG. 1 is a schematic structural view of an oil pipe recovery supporting anchor device according to an embodiment of the present invention; FIG. 2 is a schematic view of an upper end of an anchoring suspension assembly according to an embodiment of the present invention; as shown in fig. 1 in conjunction with fig. 2: an oil pipe salvaging and supporting anchor device is connected with an oil pipe at the upper part to form an oil pipe string, and particularly comprises a clamping jaw 5, wherein the clamping jaw 5 is used for butting and meshing a clamping groove 8 of an anchoring and hanging device; after the oil pipe salvaging supporting anchor device is butted with and occluded with the clamping groove 8 of the anchoring suspension device through the clamping jaw 5, the oil pipe string is continuously lifted, and the purpose of recovering the anchoring suspension device which meets the clamping is achieved.
In fig. 1, the jaws 5 are attached to the body 1, and the upper part of the body 1 has a screw thread structure by means of which the body 1 is connected with the upper oil pipe to form a string of oil pipes.
In fig. 1, a jaw groove 7 is formed in the side wall of a body 1, a jaw 5 is fixed in the jaw groove 7 through a jaw shaft 4 and a hoop spring 3, the jaw 5 is driven to rotate around the jaw shaft 4 by the gravity of an oil pipe string, the jaw 5 rotates to a position in butt joint with a clamping groove 8, then the jaw 5 is reset through the hoop spring 3, and the jaw 5 is occluded with the clamping groove 8 after being reset.
Specifically, the jaw shaft 4 may be a strong bolt and then be connected to the body 1 by a screw.
In fig. 1, the lower part of a body 1 is connected with a limiting ring 6, the limiting ring 6 is fixed on the body 1 through welding, and a jaw 5 is limited in a jaw groove 7 through the limiting ring 6 to move.
In fig. 1, the body 1 is provided with circulation holes 2, through which circulation holes 2 downhole fluid flows during lowering of the tubing string downhole for reducing the lowering resistance of the tubing string.
Specifically, the working process of the oil pipe fishing supporting anchor device of the present invention is briefly described with reference to fig. 1-2:
the device is applied to throwing type high-energy gas fracturing construction. After construction is finished, the tool string in the well sequentially comprises an anchoring suspension device, a long-delay detonator and a gunpowder core tube from top to bottom.
When the underground tool string is blocked, the supporting anchor recovery device is lowered through the cable, and the underground tool string cannot be recovered, the supporting anchor device can be salvaged by lowering the oil pipe through the oil pipe, so that the underground tool string can be salvaged. When the claw 5 contacts the upper end of the anchoring suspension device (see figure 2), under the gravity action of the oil pipe string, the claw 5 rotates around the claw shaft 4, the upper end of the claw 5 moves outwards, the lower end of the claw 5 moves inwards, the inner diameter of the oil pipe salvaging and supporting anchor device is increased, and the upper end of the anchoring suspension device enters the anchoring suspension device. Until the oil pipe is lowered to meet the resistance. At the moment, the upper end of the clamping jaw 5 moves to the lower end of the clamping groove 8 of the anchoring and hanging device. Then, the oil pipe string is lifted, when the upper end of the jaw 5 moves into the clamping groove 8 of the anchoring suspension device, the jaw 5 rotates around the jaw shaft 4 due to the elasticity of the hoop spring 3, the upper end of the jaw 5 moves inwards, and the lower end of the jaw 5 moves outwards. At the moment, under the limiting action of the limiting ring 6, the upper ends of the clamping claws 5 are occluded with the clamping grooves 8 of the anchoring and hanging device. And continuously lifting the pipe string, and recovering the tool string meeting the card.
The above-mentioned embodiments are merely embodiments for expressing the invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, substitutions, modifications, etc. can be made without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
