Abstract
The utility model relates to an oil field borehole operation is with a multi -functional salvage section of thick bamboo. The main problem of solving flexible junks such as the unable wire rope of salvage of a current salvage section of thick bamboo. Its characterized in that: barrel (4) inside upper end is connected with inner tube (3), and inner tube (3) internal surface is equipped with the saw -tooth thread, and the side has spiral slips (5) barrel (4) middle section in, and spiral slips (5) lower part is spacing through calorie key (6), barrel (4) sub -unit connection has guide shoe (7). This oil field borehole operation is with a multi -functional salvage section of thick bamboo can salvage flexible junks such as wire rope again in order to salvage pipe pole class fish, has improved salvage efficiency and success rate.
Description
Technical field
The utility model relates to oilfield, specifically a kind of oilfield downhole operation Multifunction fishing cylinder for underground work.
Background technology
On current oil field, fishing socket is conventional underground operation tool, salvages out by down-hole fish by fishing socket.But current slip-type fishing socket is salvaged for oil pipe, beam hanger and downhole tool etc. mostly, and when wire rope, rubber flexibility junk appears in down-hole, slips cannot clamp, and makes salvaging effect bad, have impact on operating efficiency.
Summary of the invention
The deficiency of the flexible junks such as wire rope cannot be salvaged in order to overcome existing fishing socket, the utility model provides a kind of oilfield downhole operation Multifunction fishing cylinder, namely this oilfield downhole operation Multifunction fishing cylinder can salvage pipe bar class fish, can the flexible junks such as wire rope be salvaged again, improve and salvage efficiency and success rate.
The technical solution of the utility model is: a kind of oilfield downhole operation Multifunction fishing cylinder, comprise top connection, top connection bottom is connected with cylindrical shell, described inner barrel upper end is connected with inner core, and interior tube inner surface is provided with saw-tooth thread, be equipped with spiral slips inside cylindrical shell stage casing, and spiral slips bottom is spacing by card key, described cylindrical shell bottom is connected with guide shoe.
Described inner core is fixed by screws on cylinder lateral wall.
The utility model has following beneficial effect: owing to taking such scheme, spiral slips and inner core is connected with in the cylindrical shell of this fishing socket, and interior tube inner surface is provided with saw-tooth thread, like this, when fishing, spiral slips can salvage the fish such as pipe, bar, and for flexible junks such as wire rope, major part can be stuck on the sawtooth of interior tube inner surface, then by rotating fishing socket, make wirerope-winding on inner core, thus salvaged well.This fishing socket not only can salvage the fish such as pipe, bar, can also salvage the flexible junks such as wire rope, frequently change fishing tool when avoiding fishing, substantially increases and salvages efficiency and success rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-top connection in figure, 2-packing, 3-inner core, 4-cylindrical shell, 5-spiral slips, 6-card key, 7-guide shoe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of oilfield downhole operation Multifunction fishing cylinder, comprises top connection 1, and top connection 1 bottom is connected with cylindrical shell 4, and cylindrical shell 4 bottom is connected with guide shoe 7.Described cylindrical shell 4 inner upper end is connected with inner core 3, and inner core 3 inner surface is provided with saw-tooth thread, is provided with packing 2 between top connection 1 bottom and inner core 3.In order to avoid mutually rotating between inner core 3 and cylindrical shell 4, inner core 3 can be fixed by screws on cylindrical shell 4 sidewall.Cylindrical shell 4 is equipped with spiral slips 5 inside stage casing, and spiral slips 5 bottom is spacing by card key 6, by contact of incline plane between cylindrical shell 4 and spiral slips 5, and spiral slips 5 inner surface is provided with thread, like this when salvaging down-hole fish, it is inner that fish is guided to cylindrical shell 4 by guide shoe 7, is placed in spiral slips 5 inner, upper carry fishing socket time, cylindrical shell 4 moves up, spiral slips 5 moves down relative to cylindrical shell 4 under the weight of fish, inwardly shrinks along inclined-plane, thus is blocked by fish.
Described inner core 3 internal diameter is less than spiral slips 5 internal diameter, and when there is the flexible junk such as wire rope, rubber down-hole, wire rope can guide in cylindrical shell 4 by guide shoe 7, and spiral slips 5 cannot block, and wire rope then can enter in inner core 3.At this moment, rotate fishing socket, inner core 3 together can rotate with fishing socket, and the buttless thread of inner core 3 inside can block wire rope, then on carry fishing socket, wire rope can be proposed.
This underground work Multifunction fishing cylinder not only can salvage pipe, bar class fish, also can salvage the flexible trouble of lost tool in holes such as wire rope, frequently change fishing tool when avoiding fishing, improves and salvages efficiency and success rate.
Claims (2)
1. an oilfield downhole operation Multifunction fishing cylinder, comprise top connection (1), top connection (1) bottom is connected with cylindrical shell (4), it is characterized in that: described cylindrical shell (4) inner upper end is connected with inner core (3), and inner core (3) inner surface is provided with saw-tooth thread, be equipped with spiral slips (5) inside cylindrical shell (4) stage casing, and spiral slips (5) bottom is spacing by card key (6), described cylindrical shell (4) bottom is connected with guide shoe (7).
2. oilfield downhole operation Multifunction fishing cylinder according to claim 1, is characterized in that: described inner core (3) is fixed by screws on cylindrical shell (4) sidewall.
