Abstract
The utility model provides an oil field is junk in pit and is salvaged a section of thick bamboo, characterized by upper portion installs piston (2) of taking rubber ring (4) through shear pin (12) in barrel (3), and piston (2) lower extreme connects gradually cassette (5) that have jump ring (6), torsion square bar (7) and stock (8) that have the outer hook. The utility model is used for in the operation is salvaged to rope class junk in the pit, inside anchor rod (8) of accessible fluid pressure type wedged compaction fish top to can guarantee the effect of salvaging the operation.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of oil field trouble of lost tool in hole fishing socket of workover treatment.
Background technology: before the utility model, each oil field is used for the outer hook of down-hole rope class fishing junk, realizes salvaging purpose in the very difficult wedging junk when meeting the top of fish of its compacting, puies forward situations such as the junk unhook also can take place in the process and influences operation effectiveness in salvaging simultaneously.
Summary of the invention: the purpose of this utility model is: for down-hole rope class fishing junk provides a kind of oil field trouble of lost tool in hole fishing socket, because this device is the anchor pole that is provided with fluid pressure type in casing section mill, can wedge the top of fish inside of compacting, thereby guarantee the effect of fishing.
The purpose of this utility model realizes by following measure: a kind of oil field trouble of lost tool in hole fishing socket, comprise joint, piston, cylindrical shell, cushion rubber, deck, jump ring, torsion square bar, cover milling head, and the cylindrical shell inner tube wall bottom of upper end field joint, lower end installation sleeve milling head is equipped with card tooth, torsion square opening, interior hook, it is characterized in that the cylindrical shell internal upper part is equipped with the piston of a band cushion rubber by shear pin, simultaneously the piston lower end connects deck, the torsion square bar that has jump ring and the anchor pole that has outer hook successively.
The utility model is used for down-hole rope class fishing junk operation, can wedge compacting top of fish inside by the fluid pressure type anchor pole, thereby guarantee the effect of fishing.
Description of drawings: Fig. 1 is the structural representation of oil field trouble of lost tool in hole fishing socket.
The specific embodiment: oil field trouble of lost tool in hole fishing socket, the cylindrical shell 3 inner tube wall bottoms of its upper end field joint 1, lower end installation sleeve milling head 11 are equipped with card tooth, torsion square opening 9, interior hook 10, cylindrical shell 3 internal upper parts are equipped with the piston 2 of a band cushion rubber 4 by shear pin 12, and simultaneously piston 2 lower ends connect deck 5, the torsion square bar 7 that has jump ring 6 and the anchor pole 8 that has outer hook successively.
The operating principle of oil field trouble of lost tool in hole fishing socket with using method is: earlier by joint 1 this device is connected also the class junk top of fish place that restricts under the lower going-into-well with fishing string during operation, overlap to mill by cover milling head 11 then junk is introduced in the cylindrical shell 3, adding hydraulic pressure by fishing string again promotes piston 2 to overcome shear pin 12 descending, and the compacting top of fish in the drive anchor pole 8 wedging cylindrical shells 3, the torsion square opening 9 that while torsion square bar 7 enters on cylindrical shell 3 inwalls, jump ring 6 on the deck 5 is stuck in card tooth on cylindrical shell 3 inwalls and makes anchor pole 8 location, this moment just can on carry fishing string and finish fishing.
