Abstract
The utility model relates to an overlength stroke downhole bailing device for oil well bailing operation comprises water connectors 1, long connecting rod 2, sealed supporting ware 3, upper and lower slot screen pipe 4, 9, the flourishing sand pipe of long pump barrel 5, piston 6, scraping ring 7, valve 8, bottom valve 10, one-way scraping leather cup 11, the ware of pounding 12. The underground bailing device has reasonable structure and reliable work, and the swabbing capacity and swabbing efficiency are obviously improved due to the adoption of the long connecting rod and the long barrel sand containing pipe, so that the bailing operation efficiency and the production time efficiency of an oil well are greatly improved, and the underground bailing device is suitable for popularization and application.
Description
The utility model relates to a kind of downhole hardware that oil well drags for the sand operation that is used for.
Oil well is in recovery process, and the sand grains in the loose oil reservoir is carried into pit shaft by oily stream inevitably, forms the sand post when serious, stops up oil flow channel, influences the oil well ordinary production.For this reason, the on-the-spot needs often carries out sand washing or drags for the sand operation oil well.At present, usually the down-hole sand pumping device stroke that adopts when dragging for the sand operation is less, thereby influence its pumping power and mulling liquid enters sand-filling cylinder in the pit shaft when dragging for sand continuity, make that to drag for the sand operating efficiency lower, all can not be satisfactory on work effect and progress, directly have influence on oil well production timeliness and economic benefit.
The purpose of this utility model is to provide a kind of ultra-long-stroke down-hole sand pumping device that can improve pumping power greatly and drag for the sand operating efficiency.
The utility model is to realize like this.This kind down-hole sand pumping device is made up of water out adapter, long connecting rod, sealing bearing apparatus, upper and lower cutting seam sieve tube, long pump barrel sand-holding tube, piston, the ring of strike-ofing, travelling valve, bottom valve, unidirectional leather cup and the rramming device of strike-ofing, its structure, assembling feature are as follows: the long connecting rod upper and lower end is respectively with water out adapter and the piston of being threaded, piston next coming in order strike-off to be threaded ring, travelling valve and following cutting seam sieve tube; Long connecting rod places in the long pump barrel sand-holding tube, long pump barrel sand-holding tube upper and lower end has last cutting seam sieve tube and bottom valve with the screw thread tipping respectively, be connected to the rramming device under the bottom valve, the bottom is pressed with the unidirectional leather cup of strike-ofing by pressure ring, and last cutting seam sieve tube upper end is connected to the outer sealing bearing apparatus of suit long connecting rod with screw thread.After this ultra-long-stroke sand pumping device finishes by above-mentioned assembling, water out adapter and wire rope or oil pipe, sucker rod are connected, and it is carried G.I.H.After the rramming device of its lower end runs into the sand face, continue to transfer tubing string, piston, long connecting rod, following cutting seam sieve tube, water out adapter etc. continue descending under action of gravity at this moment, the interior bottom valve upper liquid of long pump barrel sand-holding tube is opened travelling valve along following cutting seam sieve tube and is entered in piston cavity and the long connecting rod, upwards flow to the water out adapter place and discharge, cutting seam sieve tube enters additional on being flowed through by liquid in the pit shaft in the space at piston top and pump barrel annular space place.When cutting seam sieve tube and descent of piston are to the bottom valve position instantly, on carry wire rope or tubing string, at this moment, travelling valve is closed, and bottom valve is opened, partially liq unidirectional leather cup and the rramming device of strike-ofing of flowing through under the fluid column differential pressure action in the pit shaft, sand setting in the well is risen, enter jointly in the long pump barrel sand-holding tube.Reduction along with sand face in the pit shaft, rramming device and pump barrel etc. continue descending under action of gravity, the mulling liquid bottom valve that continues to flow through enters in the pump barrel, the liquid in piston top loop vacancy, discharge through last cutting seam sieve tube, when piston walks to sealing bearing apparatus position, blocked, finish a reciprocation cycle by the positioning joint on the bearing apparatus.Second stroke depth of setting drags for the shared volume of sand depth difference according to preceding one-stroke and is converted to sand-filling cylinder from the up shared volume of bottom valve and highly come to determine.So repeatedly, by repeatedly transferring sand pumping device (being a plurality of reciprocation cycle), eliminate or till the sand face drops to designing requirement until sand setting.
The utility model is reasonable in design, and reliable operation owing to adopted long connecting rod and long pump barrel sand-holding tube, obviously improves its pumping power and pumping efficient, drags for sand operating efficiency and oil well production timeliness thereby improved greatly, is suitable for and applies.
Accompanying drawing is general structure of the present utility model and operating principle schematic diagram.Among the figure, label " 13 " is wire rope or oil pipe, sucker rod, and " 14 ", " 15 " are respectively liquid level and sleeve pipe, and " 16 " use interior box cupling for long connecting rod connects, " 17 ", " 18 " are respectively mulling liquid and pit shaft sand setting, and " 19 ", " 20 " are respectively artificial bottom of a well and oil reservoir.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
As shown in the figure, the utility model by water out adapter 1, long connecting rod 2, sealing bearing apparatus 3, upper and lower cutting seam sieve tube 4,9, long pump barrel sand-holding tube 5, piston 6, strike-off encircle 7, travelling valve 8, bottom valve 10, unidirectional leather cup 11 and the rramming device 12 of strike-ofing form.Wherein, long connecting rod 2 is hollow round bar, and box cupling connects and composes in being adopted by the more piece short connecting rod.Upper and lower cutting seam sieve tube 4,9 is to be evenly equipped with the pipe that numerous longitudinal slots and upper and lower end are respectively equipped with screw thread on perisporium.Long pump barrel sand-holding tube 5 upper and lower ends are threaded respectively, and bottom surface central authorities are provided with double as valve seat circular hole.Piston 6 is the threaded hollow circular cylinder of upper and lower end.The unidirectional leather cup 11 usefulness rubber of strike-ofing are made, and hollow is the bowl-shape of back-off.Rramming device 12 is that a upper end is threaded, the short tube of lower end indentation.
