Abstract
The utility model discloses a logging cable fishing spear with a wall hook. The logging cable fishing spear with the wall hook is reasonable in structure and can be used for effectively fishing a logging cable. The logging cable fishing spear with the wall hook comprises a fishing spear body, wherein screw threads are arranged at one end of the fishing spear body, the wall hook is arranged at the other end of the fishing spear body, a plurality of spear hook protrusions are arranged on the fishing spear body, and the wall hook is of a C-shaped bent structure with a parallel line in the length direction of the fishing spear body as the central axis. The logging cable fishing spear with the wall hook is reasonable in structure, simple to manufacture, convenient to use, and high in cable fishing efficiency.
Description
Technical field
The utility model relates to a kind of fishing device of the logging cable with wall hook.
Background technology
In the logging operation process, when the logging cable fracture occurs after, if fracture attempts existing with high-tension trial unfreezing or Open-Hole Section the sandstone well section of thick-layer early stage, can make the cable of fracture be close to the borehole wall, conventional logging cable fishing spear is due to the impact of lance hook design, thereby can not reach, the cable of being close to the borehole wall is peeled off to the purpose that is wrapped in the fishing spear body, increased the processing time.
The utility model content
For the problems referred to above, it is a kind of rational in infrastructure, easy to make that the utility model provides, and can effectively salvage the fishing spear of the logging cable with wall hook of the cable be attached on the borehole wall.
For achieving the above object, the logging cable fishing spear of the utility model band wall hook, comprise the fishing spear body, described fishing spear body one end is provided with screw thread, the other end is provided with wall hook, described fishing spear body is provided with some lance hook projections, the C shape bending structure that wherein said wall hook is axle centered by the parallel lines of described fishing spear body length direction.
Further, the arc groove structure that described fishing spear body is strip, be provided with some lance hook projections at the cell wall top of described groove, be provided with some lance hook projections in the inside of described groove.
Further, the inside of the lance hook at the cell wall top of described groove projection and described groove is provided with the top of some lance hook projections on same horizontal plane.
Especially, described lance hook projection is triangular structure.
Preferably, the circumferential size of the size of the described wall hook of C shape bending and described well is suitable.
Further, described fishing spear body and described wall hook and described screw thread are structure as a whole.
The logging cable fishing spear of the utility model band wall hook, with rotation drilling tool, be connected, rotation drilling tool drives this fishing spear and rotates, owing to having designed the wall hook structure, by wall hook, cable is peeled off from the borehole wall, and under the drive of rotation drilling tool, this fishing spear rotates, cable winding is on the fishing spear body, described lance hook projection is for attached cable, logging cable with wall hook fishing spear described in the utility model, rational in infrastructure, easy to make, scene just can be made, processing timeliness while having saved complicated well logging accident treatment, improved operating efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of the logging cable fishing spear of the utility model band wall hook.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
The logging cable fishing spear of the utility model band wall hook, comprise the fishing spear body, described fishing spear body one end is provided with screw thread, the other end is provided with wall hook, described fishing spear body is provided with some lance hook projections, the C shape bending structure that wherein said wall hook is axle centered by the parallel lines of described fishing spear body length direction.
As shown in Figure 1, the logging cable fishing spear of the present embodiment band wall hook, comprise fishing spear body 3, described fishing spear body one end is provided with screw thread 4, the other end is provided with wall hook 1, described fishing spear body is provided with some lance hook projections 2, the C shape bending structure that wherein said wall hook is axle centered by the parallel lines of described fishing spear body length direction.
Further, for convenient, make, the arc groove structure that described fishing spear body is strip, be provided with some lance hook projections at the cell wall top of described groove, be provided with some lance hook projections in the inside of described groove.
Further, in order to facilitate the fixing of cable, the lance hook projection at the cell wall top of described groove and the inside of described groove are provided with the top of some lance hook projections on same horizontal plane.
Especially, described lance hook projection is triangular structure.
Described fishing spear in the present embodiment is connected with the conversion pipe nipple by screw thread 4, and the conversion pipe nipple is connected with drilling tool.Salvage in the cable process at lower brill, drive this device by rotation drilling tool and rotate, the wall hook 1 of front end by cable from the borehole wall is peeled off, in rotation process by cable winding on this device body 3, after fixing by lance hook 2, cable can be salvaged out from well.
The logging cable fishing spear of the present embodiment band wall hook, with rotation drilling tool, be connected, rotation drilling tool drives this fishing spear and rotates, owing to having designed the wall hook structure, by wall hook, cable is peeled off from the borehole wall, and under the drive of rotation drilling tool, this fishing spear rotates, and cable winding is on the fishing spear body, and described lance hook projection is for attached cable, the described fishing spear of the logging cable with wall hook of the present embodiment, rational in infrastructure, easy to make, scene just can be made, processing timeliness while having saved complicated well logging accident treatment, improved operating efficiency.
Can be in the following ways in the making of the fishing spear of the logging cable with wall hook described in above-described embodiment, by the short sleeve matched with borehole size, make, sleeve pipe screw thread end portion is cut to 2/3, cut respectively the lance hook projection of some triangular structures in residue 1/3 body part left and right, and weld some triangle steel plates in the inside middle position, as lance hook projection.After cutting casing shoe along circumference, as wall hook, described fishing spear body and described wall hook and described screw thread are structure as a whole, and the size of the described wall hook of C shape bending and the circumferential size of described well are suitable.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
