Abstract
The utility model relates to a guide shoe for the fishing tool of a logging instrument, and the guide shoe is a cavity sleeve tube, wherein alloy teeth are uniformly distributed on a circumference surrounding one port of the cavity sleeve tube, a nick is formed in the circumferential wall of the port, the nick is provided with a larger interior and a smaller exterior, the open end is provided with a clamping ledge, and the opening of the clamping ledge is a shifting tongue; a screw thread is formed at the other end of the cavity sleeve tube, a conversion short joint is rotatably connected to the screw thread, and the other end of the conversion short joint is rotatably connected with a fishing barrel. The guide shoe disclosed by the utility model is simple in structure, easy to machine, capable of being rapidly manufactured on the scene, convenient and fast to use, and capable of greatly increasing the handling timeliness during complex logging accident handling.
Description
Technical field
The utility model relates to a kind of salvaging logging instrument instrument guide shoe that uses in petroleum works Oil/gas Well well logging accident.
Background technology
In the logging operation process, after the generation logger falls the well accident, if because deal with improperly in hole condition or early stage, cause sand setting too much to bury instrument, later stage salvaging intractability is relatively large so, and conventional well logging salvaging instrument guide shoe is horseshoe type, can not effectively process this, after can only adopting the first sand setting processing with the instrument top of casing section mill, then fishing tool is processed down, has increased the processing time.
Correlation technique content of the present utility model has no report.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to make, when sand setting is arranged at the instrument top, after can removing sand setting by this device of activity drilling well driven by rotary disc, make instrument can enter smoothly the salvaging logging instrument instrument guide shoe of fishing socket.
Technology contents of the present utility model is: salvaging logging instrument instrument guide shoe is a cavity sleeve pipe, the even circumferential distribution alloy teeth of ring one port are offered breach on the circle wall of this port, and are large outer little in described breach, this openend is provided with the card rib, and this Ka Lengkou is and dials tongue.The other end at the cavity sleeve pipe is offered screw thread, the conversion pipe nipple that spins on screw thread, and conversion pipe nipple another end and fishing socket spin.
The utility model is simple in structure, and handling ease can be made at the scene fast.It is easy to use, the processing timeliness in the time of can improving in a large number complicated well logging accident treatment.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is salvaging logging instrument instrument guide shoe structural representation.
Legend: 1. alloy teeth, 2. group tongue, 3. cavity sleeve pipe, 4. conversion pipe nipple.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
As shown in Figure 1, salvaging logging instrument instrument guide shoe is a cavity sleeve pipe 3, and the even circumferential distribution alloy teeth 1 of ring one port are offered breach on the circle wall of this port, and large outer little in described breach, this openend is provided with the card rib, and this Ka Lengkou is and dials tongue 2.The other end at cavity sleeve pipe 3 is offered screw thread, and the conversion pipe nipple 4 that spins on screw thread is offered internal thread in conversion pipe nipple 4, and conversion pipe nipple 4 another ends and fishing socket spin.
In lower brill salvaging process, if the slight phenomenon that is hampered is arranged, can rotary turnplate, rotating disk is the parts on rig, and the power of rotation is provided for fishing socket, thereby drives cavity sleeve pipe 3, utilizes 1 pair of borehole wall of alloy teeth to process; If sand setting is arranged at the instrument top, can by the mode of turn on pump and rotary turnplate, sand setting be circulated out; Simultaneously, group tongue 2 of this device also helps in big hole to be dialled in instrument in cavity sleeve pipe 3, utilizes instrument to enter fishing socket.
In addition, if the instrument body is buried by sand setting, only need to connect between this device and conversion pipe nipple 4 in the salvaging process and the sleeve pipe of cavity sleeve pipe 3 same sizes, namely can be used as the lengthening guide shoe, thereby guarantee the integrality of instrument in the salvaging process.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
