Description
Technical field:
The utility model relates to a kind of spiral groove type fishing cup that oilfield well milling fishing is used.
Background technology:
The fishing cup that uses in present most of oil field milling workover treatment process all adopts single tubular strainer formula structure, makes landwaste up at the bottom of elder generation's turn on pump flushing manhole during use, and termination of pumping then relies on action of gravity to make landwaste sink to dropping in the fishing cup.Gap between its external diameter of the dipper of this kind structure and pit shaft or the internal surface of sleeve pipe is less, and difficult being rinsed by annular clearance of bulk landwaste that produces in the milling process and milling tool cast returned fishing cup top.In addition, fall into the restriction that the interior probability of fishing cup is subjected to the dipper diameter again in the landwaste precipitation process, the part landwaste sinks to the shaft bottom again, and often salvaging is not thorough, and effect is relatively poor, even dipper place lock of tool drilling easily takes place.Therefore be necessary to design a kind of simple in structure, make full use of the fluid flushing effect and improve the novel practical fishing cup of salvaging effect.
The utility model content:
The purpose of this utility model provides a kind of spiral groove type fishing cup, this fishing cup has solved the tubular strainer formula structure fishing cup of the routine usefulness that exists in the prior art, the gap is less between its external diameter and pit shaft or the internal surface of sleeve pipe, and bulk landwaste in the milling process and junk are difficult for being rinsed and return fishing cup top; Often salvaging is not thorough, and effect is relatively poor, even the problem of dipper lock of tool drilling easily takes place.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spiral groove type fishing cup by drill pipe nipple, trip bolt, fishing cup lid, fluid passage district, enclosed area, fan-shaped dipper wall, slot type at the bottom of cup, connect pipe nipple, stirring sheet is formed; The drill pipe nipple upper and lower side all has screw thread, slot type base ring to be made of a plurality of secter pats, and is welded on the drill pipe nipple bottom; The welding of the secter pat of fan-shaped dipper wall bottom and slot type base ring annular external diameter, and the quantity of the quantity of secter pat and fan-shaped dipper wall is identical, and to be generally 3-5 individual; Be distributed with the space on the covering of the fan of dipper wall, be convenient to fluid and pass through; Fan-shaped dipper wall forms two sidewalls of sector drum along dotted line bending back; Fan-shaped dipper wall left side wall is provided with the inlet that a plurality of breach form dipper, entity part and drill pipe nipple welding between breach; The right side wall of fan-shaped dipper wall and drill pipe nipple welding back form the enclosed area; What two sidewalls of adjacent two fan-shaped dipper walls formed enough spaces revolves the type runner, the fishing cup lid is installed dipper top early, its end face forms circle, fishing cup covers fluid passage district and the enclosed area that distributes with dipper wall same number, the entity in fluid passage district is provided with bar shaped or circular hole, forms on the fluid and returns passage; The enclosed area of fishing cup lid covers the top of spiral fluid passage, forces fluid to enter in the dipper by the dipper sidewall; The fluid passage district covers the top port of export of dipper wall, guarantees to return and landwaste and other bulk cast are limited in the dipper from the space outflow of top fishing cup lid; The fishing cup lid is fixedlyed connected with drill pipe nipple by trip bolt, adjusts opening and sealing of fishing cup lid, and agitator is a spiral groove type fishing cup annex, constitutes by connecting pipe nipple and stirring sheet, and is provided with high speed nozzle, can cooperate the spiral groove type fishing cup to use.
During construction, spiral groove type fishing cup top is connected with drilling tool, and the bottom connects milling tool.The shaft bottom landwaste returns under the high speed flushing action of fluid and enters in the spiral groove type runner, and when drilling tool clockwise rotated, under fluid flow fields and landwaste effect of inertia, the bulk landwaste entered in the dipper by the breach on runner right side.Fluid is by the up outflow dipper in fluid passage district of dipper lid, and landwaste is blocked in the dipper.When treating that construction finishes, take out dipper, the trip bolt of removal spiral groove type fishing cup is also gone up the bailing bowl cover makes the upper end of dipper open, taking-up landwaste after fishing cup is inverted.
In addition, also spiral groove type fishing cup and its annex agitator can be coupled together, special boring down salvaged.Shaft bottom landwaste and milling tool cast are carried by turbulent fluid and enter the spiral groove type fishing cup returning on rapidly under the effect of rapid impact of the rotation stirring of stirring sheet and high speed nozzle, and it is better to salvage effect.
The beneficial effects of the utility model are that this use new structure is simple, and is easy to use, can use separately also to cooperate milling tool to use; This fishing cup flow channel space is big, makes full use of the runner characteristic, has significantly improved the salvaging effect, salvages thoroughly, salvages especially obvious for the bulk landwaste.
