Description
Relate to the field
The utility model relates to kind of the instrument in cleaning shaft bottom, oil field, specifically, is two cone fishers.
Background technology
At present, the fisher that use the cleaning in shaft bottom in each oil field is single salvaging, waste time and energy, and complex operation, and not thorough to the cleaning in shaft bottom, efficiency is low.
Technology contents
The purpose of this utility model is to provide a kind of collection fishing cup, strong magnetic die and " tackling all problems at once " three kinds of functions be one, compact conformation, easy to operate, can purify the shaft bottom by high-efficiency multi-function, but also the two cone fishers with the function that can salvage a plurality of gear wheels.
The utility model is achieved in that and comprises body 1, outer dipper 2, interior six square joints 3, outer six square joints 4, hang pin 5, the urceolus 6 of coring, interior gland 7, inner shield ring 8, magnet 9, sheath 10, the inner core 11 of coring, core grabber 12, milling shoe 13, steel ball 14, sealing ring 15, telescopic 16, spring 17, outer dipper 2 is enclosed within on the body 1, body 1, interior six square joints 3, outer six square joints 4, the urceolus 6 of coring connects successively, in outer six square joints 4 telescopic 16 is housed, the inner core 11 of coring in the urceolus 6 of coring, in interior six square joints 3, steel ball 14 is equipped with at the top of telescopic 16, the bottom of this device is provided with core grabber 12, milling shoe 13 has sealing ring 15 between interior six square joints 3 and the telescopic 16.
The utility model also adopts following technical scheme:
In six square joints, 3 usefulness suspension pin 5 be connected with outer six square joints 4.
Between outer six square joints 4 and the telescopic 16 spring 17 is housed.
The bottom of spring 17 is provided with interior gland 7, inner shield ring 8.
Drag for bucket 2 and body 1 outward with bolt.
The bonding surface of interior six square joints 3 and outer six square joints 4 is regular hexagon structures.
Spring 17 is installed in interior six square joints 3, and is fixed by interior gland 7.
Telescopic 16 internal diameters are less than body 1 internal diameter.
Advantage of the present utility model is: the collection fishing cup, strong magnetic die and " tackling all problems at once " three kinds of functions are one, compact conformation, easy to operate, can efficiently purify the shaft bottom, but also have the function that to salvage a plurality of gear wheels, realize inside and outside with dragging for, size is dragged for entirely, two a kind of new-type fishing tools that gear wheel can drag for to reducing exoil field cost, improve a fishing success ratio and play an important role.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a local enlarged diagram of the present utility model.
Concrete enforcement
As shown in Figure 1 and Figure 2, mainly form by body 1, outer dipper 2, interior six square joints 3, outer six square joints 4, suspension pin 5, the urceolus 6 of coring, interior gland 7, inner shield ring 8, magnet 9, sheath 10, the inner core 11 of coring, core grabber 12, milling shoe 13, steel ball 14, sealing ring 15, telescopic 16, spring 17
Body 1 upper end processing criterion drill rod thread is connected with drilling rod, and hypomere is connected with outer six square joints 4, mainly is to transmit torque and the outer bucket 2 that drags for is installed.Dragging for bucket 2 outward and install on the body 1, mainly is the smallclothes junk in shaft bottom when salvaging direct circulation by the reducing of its position body 1.
Outer six square joints 4 mainly are to transmit torque and transmit the pressure of the drill.Torque is passed to interior six square joints 3 and the pressure of the drill is passed to inner core 11, the inside mounting spring 17 of outer six square joints 4, this device is fixed on it.
Interior six square joints 3 mainly are that transmission torque and outer six square joints 4 play guide effect together.
The urceolus 6 of coring mainly is to transmit torque and protect core grabber, be not damaged.
Core grabber 12 main effects are to salvage gear wheel and fish for the bulk bottom hole falling article.
The main effect of milling shoe 13 is when fishing tool is gone into the well, and stirs the central authorities that bottom hole falling article is assembled well when meeting obstructions the salvaging of carrying out reaming expansion well.
The inner core 6 main effects of coring are to drive magnet 9 by stretching out of telescopic 16 to move down, and near the junk the shaft bottom that reaches milling shoe 13 inlets holds, and resets by spring 17 junk is brought into inner core 11.Steel ball 14 mainly is 16 pressurizations of sealing telescopic, makes telescopic 16 actions.
Its operating principle is according to fishing cup, and magnetic drags for the working condition of device and (tackling all problems at once), cleverly in conjunction with the three.During work, instrument is little of the shaft bottom, the turn on pump circulation, rotation is also gone up among a small circle, following active tool, the shaft bottom is bored and is taken out of from the instrument outer annular space by drilling fluid, when arriving cup nozzle portion, because it is big that annular space becomes suddenly, the drilling fluid flow velocity descends, and heavier mincing just falls in the cup tube.Termination of pumping, low speed rotation instrument be down to the shaft bottom, stirs through mud flush with milling shoe 13 and bear against gear wheel at the borehole wall, bulk junks such as pincers tooth drop into steel ball 14 back turn on pumps to well central authorities, send steel ball 14 to telescopic 16 end face seals place, after steel ball 14 falls into, the pump pressure 1-2MP that can rise suddenly.Spring 17 moves downward under the effect of fluid power, drives magnet 9 and moves downward to milling shoe 13 entrance, treat that magnet 9 is drawn onto the gear wheel of well after, termination of pumping.After treating that spring 17 resets, the shaft bottom gear wheel that magnet 9 is inhaled is also together followed telescopic 16 and is raised.
After the process for the treatment of is finished, press down drilling tool, at this moment outer six square joints 4 are cut off suspension pin 5 and are pressed down the inner core 6 of coring, and the inner core 6 of coring transmits satin to outer the pressure of the drill and forces core grabber 12 to curve inwardly for core grabber 12, core grabber 12 is just held junk tightly like this, has realized the salvaging of second gear wheel.So just, can carry and having bored.
Use this kind fisher can salvage 1-2 gear wheel and general common fisher can only be salvaged a gear wheel, and common cone fisher has just lost to act on and can only adopt junk mill to grind a kind of method when two gear wheels fall well.This pair cone fisher can be saved the trip time 2-3 time when two gear wheels of salvaging fall well, can save 2-3 junk mill, and economic benefit is considerable, fully can be at alternative other conventional fishing tool in ordinary circumstance.
