Abstract
A kind of bleeder.Mainly solve existing drainage device easily to lose efficacy, sealing effectiveness is poor, produces easily leakage, the problem of structure and complicated operation when oil well pump normally works.It is characterized in that: activity centre pipe (1) lower slide is connected in outer tube (2), annular inner convex platform (7) is had in outer tube (2) upper end, and be fastened in outer lug boss (6), activity centre pipe (1) and outer tube (2) corresponding wall there is leakage opening (8), outer tube (2) lower end is connected with lower contact (5), slipper seal sleeve pipe (3) is placed between activity centre pipe (1) and outer tube (2), and be connected on outer tube (2) by release pin (9), jump ring (4) is embedded in outer tube (2) inner groovy of lower contact (5) upper end, jump ring (4) internal diameter matches with slipper seal sleeve pipe (3) lower end external diameter.This bleeder has safe and reliable, good sealing effect, ensures that oil well pump normally works, structure and feature simple to operate.
Description
Technical field:
The utility model relates to a kind of oil extraction in oil field downhole tool used, especially bleeder.
Background technology:
Along with today of oil field develop rapidly, safety and environmental protection and energy-conservation be the top priority of pendulum in face of us.Sump oil effluent discharge problem particularly during workover treatment is the arch-criminal of environment pollution.In addition, want profit to let out to fall in well, drainage device of need contacting on tubing string.And existing drainage device exists and just can not complete the problem of draining if there is break de-, wax deposition, fouling or viscous crude of bar.External diameter is large, necessary and casing-contact, easily midway release during lower pipe, the problem of sealing effectiveness difference.Produce leakage when oil well pump normally works, during if there is materials such as sand, dirt, rust, easily cause down-hole accidents such as separating card crash, sleeve pipe is also had to the problem of certain damage, be unfavorable for applying.
Utility model content:
Easily lost efficacy to solve existing drainage device, sealing effectiveness is poor, produces easily leakage, the problem of structure and complicated operation when oil well pump normally works.The utility model provides a kind of bleeder.This bleeder has safe and reliable, good sealing effect, ensures that oil well pump normally works, structure and feature simple to operate.
The technical solution of the utility model is: this bleeder comprises activity centre pipe, outer tube, slipper seal sleeve pipe, jump ring and lower contact.There is Taper Pipe external screw thread pipe upper end, activity centre, outer in the middle part of the pipe of activity centre have annular outer platform, sealing ring is inlaid with in activity centre pipe groove under outer lug boss, activity centre pipe lower slide is connected in outer tube, annular inner convex platform is had in outer sleeve upper, and be fastened in outer lug boss, activity centre pipe and the corresponding wall of outer tube there is leakage opening, outer tube lower end is connected with lower contact, slipper seal sleeve pipe is placed between activity centre pipe and outer tube, and be connected on outer tube by release pin, sealing ring is inlaid with in the outer groove of slipper seal casing part, jump ring is embedded in the outer tube inner groovy of lower contact upper end, jump ring internal diameter matches with slipper seal its lower end external diameter.
The utility model has following beneficial effect: this bleeder has Taper Pipe external screw thread owing to adopting pipe upper end, activity centre, outer in the middle part of the pipe of activity centre have annular outer platform, sealing ring is inlaid with in activity centre pipe groove under outer lug boss, activity centre pipe lower slide is connected in outer tube, annular inner convex platform is had in outer sleeve upper, and be fastened in outer lug boss, activity centre pipe and the corresponding wall of outer tube there is leakage opening, outer tube lower end is connected with lower contact, slipper seal sleeve pipe is placed between activity centre pipe and outer tube, and be connected on outer tube by release pin, sealing ring is inlaid with in the outer groove of slipper seal casing part, jump ring is embedded in the outer tube inner groovy of lower contact upper end, the structure that jump ring internal diameter matches with slipper seal its lower end external diameter.Utilize slipper seal sleeve pipe change in location in outer tube, realize opening and blocking of switch leakage opening, thus reach safe and reliable, good sealing effect, ensure the object that normally works of oil well pump, and structure and simple to operate.This bleeder has safe and reliable thus, good sealing effect, ensures that oil well pump normally works, structure and feature simple to operate.
Accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation.
1-activity centre pipe in figure, 2-outer tube, 3-slipper seal sleeve pipe, 4-jump ring, 5-lower contact, 6-outer lug boss, 7-inner convex platform, 8-leakage opening, 9-release pin.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this bleeder comprises activity centre pipe 1, outer tube 2, slipper seal sleeve pipe 3, jump ring 4 and lower contact 5.Activity centre pipe 1 is tubulose, there is Taper Pipe external screw thread upper end, middle part is outer annular outer platform 6, sealing ring is inlaid with in activity centre pipe 1 groove under outer lug boss 6, activity centre pipe 1 lower slide is connected in outer tube 2, activity centre pipe 1 and tubing string connection function, meanwhile, play mobile slipper seal sleeve pipe 3 and act on.Outer tube 2 is tubulose, annular inner convex platform 7 is had in outer tube 2 upper end, and be fastened in outer lug boss 6, inner convex platform 7 and outer lug boss 6 play and prevent from activity centre pipe 1 from departing from outer tube 2 acting on, activity centre pipe 1 and the corresponding wall of outer tube 2 there is leakage opening 8, outer tube 2 lower end is connected with lower contact 5 by screw thread, outer tube 2 connection functions.Slipper seal sleeve pipe 3 is tubulose, and slipper seal sleeve pipe 3 is placed between activity centre pipe 1 and outer tube 2, and is connected on outer tube 2 by release pin 9, is inlaid with sealing ring outside slipper seal sleeve pipe 3 bottom in groove, slipper seal sleeve pipe 3 on-off actions.Jump ring 4 is embedded in outer tube 2 inner groovy of lower contact 5 upper end, jump ring 4 internal diameter matches with slipper seal sleeve pipe 3 lower end external diameter, jump ring 4 is flexible, endoporus is changeable, after slipper seal sleeve pipe 3 lower end enters jump ring 4 endoporus, slipper seal sleeve pipe 3 can be blocked by elasticity by jump ring 4, is thus opened by leakage opening 8.
During actual use, first the lower contact 5 of this bleeder is connected with oil well pump upper end, the upper end of this bleeder is connected with tubing string, connect and go into the well, when tubing string transfers to artificial bottom of a well, when tubing string weight is cut off more than four ton hour release pins 9, activity centre pipe 1 drives slipper seal sleeve pipe 3 descending, slipper seal sleeve pipe 3 lower end enters in jump ring 4, four leakage openings 8 now on activity centre pipe 1 are given by slipper seal sleeve pipe 3 and are closed, in tubing string, well liquid cannot leak, and can normally recover the oil.During job execution next time, deepen oil pipe after proposing tubing hanger to tag in fact, tubing string is carried on after connecting spy three times, activity centre pipe 1 is up, bottom stayed under the effect of jump ring 4 by slipper seal sleeve pipe 3, four leakage openings 8 now on activity centre pipe 1 and four leakage opening 8 UNICOMs on outer tube 2, in tubing string, well liquid leaks, and namely completes draining.Namely this bleeder avoids the drawback of existing drainage device, and structure and operation all very simple, external diameter is 104 millimeters, and total length is less than 60 centimetres.Not only reduced manufacturing cost but also the object of draining can have been reached.
