Abstract
A kind of spray-sucking type smallclothes collector, comprise alloy block, cover milling short circuit, junk basket assembly, outer cylinder body, inner barrel, smallclothes collecting board, spray seat, baffle and top connection, if alloy block side is top, top connection side is bottom; Alloy block is embedded on cover milling short circuit, cover milling short circuit is connected to outer cylinder body top, inner barrel is connected to baffle top, baffle establishes spray seat in top, junk basket assembly is arranged between cover milling short circuit and inner barrel, smallclothes collecting board is welded on inner barrel at a certain distance, and top connection is connected with outer cylinder body.The utility model is the underground work fishing tool of petroleum industry, and the small falling object for oilfield well is salvaged, and possesses cover milling function simultaneously, realizes cover and grind the technology measure dragged for.
Description
Technical field
The utility model belongs to the field of oil extraction in oil field engineering workover treatment instrument and technological measure, is applied in the small falling object salvage of oil gas water well, particularly relates to a kind of spray-sucking type smallclothes collector.
Background technology
In oil well technique, smallclothes fisher kind is a lot, the smallclothes fisher of current employing venturi principle design is comparatively applicable, but smallclothes are salvaged effect and are limited to, the suction that simple employing negative pressure causes is very limited, when therefore salvaging small falling object, less small falling object can salvage, and large small falling object just can not be salvaged out, Given this this spray-sucking type smallclothes collector designed mainly adopts water conservancy spray cycle, smallclothes circulation is come up, and produces suction, the small falling object in well is all salvaged out.
Utility model content
The utility model relates to the underground work fishing tool of petroleum industry, and the small falling object for oilfield well is salvaged, and possesses cover milling function simultaneously, realizes cover and grind the technology measure dragged for.For this reason, a kind of spray-sucking type smallclothes collector is designed.
A kind of spray-sucking type smallclothes collector, comprise alloy block, cover milling short circuit, junk basket assembly, outer cylinder body, inner barrel, smallclothes collecting board, spray seat, baffle and top connection, if alloy block side is top, top connection side is bottom; Alloy block is embedded on cover milling short circuit, and cover milling short circuit is connected to outer cylinder body top, and inner barrel is connected to baffle top, baffle establishes spray seat in top, junk basket assembly is arranged between cover milling short circuit and inner barrel, and smallclothes collecting board interval is welded on inner barrel, and top connection is connected with outer cylinder body.
Further, between inner barrel and outer cylinder body, O-ring seal is set.
Further, spray seat top arranges screen pack, prevents booty from entering spray chamber.
Further, spray seat bottom arranges inner nozzle.
Further, in baffle bottom, outer nozzle is set.
Further, top connection is connected outside baffle bottom.
The utility model spray-sucking type smallclothes collector can be collected the small falling object differed in size simultaneously, effectively can carry out cover milling to bottom small falling object, utilize spray cycle active force that smallclothes are suspended, principle of negative pressure is adopted to collect the small falling object suspended, the junk of entering tool adopts twin-stage to collect, make collecting effect good, while adopting guide functions power to make liquid cause hydro-peening, inner chamber produces suction again, the smallclothes that can be used for all kinds of oil gas water well are salvaged, also be applicable to horizontal well simultaneously, nozzle diameter can be changed, thus control spray chamber suction and flow, the distance controlling spray chamber suction of interior outer nozzle can be adjusted, adopt contrainjector structure, circulating effect is good, simplify, labyrinth is changed one.
Accompanying drawing explanation
Fig. 1 is spray-sucking type smallclothes collector structure figure;
Wherein: 1, alloy block; 2, cover milling short circuit; 3, junk basket assembly; 4, O-ring seal; 5, outer cylinder body; 6, inner barrel; 7, smallclothes collecting board; 8, screen pack; 9, spray seat; 10, inner nozzle; 11, baffle; 12, outer nozzle; 13, top connection.
Detailed description of the invention
Shown in Fig. 1, the utility model comprises alloy block 1, cover milling short circuit 2, junk basket assembly 3, O-ring seal 4, outer cylinder body 5, inner barrel 6, smallclothes collecting board 7, screen pack 8, spray seat 9, inner nozzle 10, baffle 11, outer nozzle 12 and top connection 13.
If alloy block 1 side is top, top connection 13 side is bottom; Alloy block 1 is embedded on cover milling short circuit 2, compress with cover milling short circuit, cover milling short circuit 2 is connected to outer cylinder body 5 top, inner barrel 6 is connected to baffle 11 top, baffle 11 establishes spray seat 9 in top, junk basket assembly 3 is arranged between cover milling short circuit 2 and inner barrel 6, and smallclothes collecting board is welded on inner barrel 6 at a certain distance, and top connection 13 is connected with outer cylinder body 5.O-ring seal 4 is set between inner barrel 6 and outer cylinder body 5.Spray seat 9 top arranges screen pack 8, prevents booty from entering spray chamber.Spray seat 9 bottom arranges inner nozzle 10.Baffle 11 arranges outer nozzle 12 in bottom.Baffle 11 connects top connection 13 outside bottom.
Operating principle: alloy block can milling smallclothes; Cover milling short circuit compresses junk basket assembly, can change after the wearing and tearing of bottom alloy block; Smallclothes can be carried during junk basket assembly liquid-circulating to pass through, stop the bailer grab in circulation time junk basket to make bailer grab return by self eccentric gravity and spring force, block smallclothes; Sealed outer cylinder body and inner barrel, complete circulation; Outer cylinder body, connects top connection and cover milling short circuit, sets up circulation; Inner barrel sealing inner/outer tube, installs smallclothes collecting board; Smallclothes collecting board plays the effect of collecting broken smallclothes; Screen pack blocks nozzle after preventing smallclothes from sucting; Spray seat installs inner nozzle, and adjustment inner nozzle distance, installs screen pack, set up circulating system; Inner nozzle is jet blower, forms high pressure jet stream; Baffle installs spray seat and outer nozzle, and make the liquid of 1/3 enter nozzle, the liquid of 2/3 enters casing annulus by the eyelet of outer cylinder body, plays guide functions; Outer nozzle is fanging noz(zle), has certain angle of incidence, at utmost makes to form negative pressure around; Top connection connects outer cylinder body and installs baffle, connects top drilling tool, set up the effect of circulation.
During work, be connected to the bottom of drilling tool according to the fish depth data determination spray-sucking type smallclothes collector depth of setting provided; Go into the well to after subscribing position, turn on pump cyclic flusher.The construction of cover milling operation can be carried out if necessary.After fully circulating, above carry drilling tool and can complete smallclothes collection.Trip out after in well, take collector apart, after pouring out the smallclothes in two-stage collection, can go into the well and carry out again smallclothes salvaging.
