Description

A kind of rod-pulling type bleeder
Technical field:
The utility model relates to a kind of mud oil technical field, particularly a kind of rod-pulling type bleeder.
Background technology:
On high angle hole and horizontal well, normally used bleeder is rod-pulling type bleeder at present.Along with the increase of horizontal well and high angle hole lower-continuous mapping, bleeder is the corresponding increase degree of depth also, residing down well placement gradient increases sharply, rod string kit (friction prevention device, anti-dropping device etc.) increases simultaneously, conventional tie rod formula bleeder is made to be difficult to adapt with it, after existing rod-pulling type bleeder is used for horizontal well or high angle hole, the subject matter of generation is when bleeder does not need to open, and is opened by rod string or fluid column pressure reduction; When needs are opened, sometimes can not open, draining difficulty, draining are not thorough.The problems such as low and operational failure of existing bleeder life-span, cause oil well pump detection period short and bring certain difficulty to workover treatment, not only increase operating cost, and easily cause well head to pollute.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of rod-pulling type bleeder, the arrangement achieves safe and reliable, life-span is long, meet the technical requirements of horizontal well and high angle hole production, make high angle hole and the effective draining of horizontal well, extend pump detection period, prevent well head from polluting, reduce operating cost.Overcome existing rod-pulling type bleeder and easily operational failure occurs, the deficiency that the life-span is short.
Technical solution adopted in the utility model is: a kind of rod-pulling type bleeder, is made up of work in combination cylinder and lifting rod; Work in combination cylinder comprises outer tube and guide pipe, guide pipe is connected on outer tube wall, guide pipe upper portion side wall axially evenly has many guide channels, outer tube wall is provided with pressure release pin, pressure release pin lower end is provided with shearing snap, shearing snap is placed in a passage on guide pipe sidewall, the outer tube wall of pressure release pin upper end has groove, the outer tube wall of shearing snap lower end has groove, back-moving spring is provided with in the groove shearing snap lower end, back-moving spring upper end is provided with a grade ring, and back-moving spring lower end withstands on guide pipe end face; Lifting rod by center-pole, rotate sliding sleeve and retainer ring and form, rotate sliding sleeve and to be sleeved on center-pole and to be fixed by retainer ring, rotate sliding sleeve outer wall and be provided with the convex key of guiding matched with guide pipe sidewall upper channel.
The beneficial effects of the utility model are: the utility model is safe and reliable, and the life-span is long, meet the technical requirements of horizontal well and high angle hole production, make high angle hole and the effective draining of horizontal well, extend pump detection period, prevent well head from polluting, reduce operating cost.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the structural representation of work in combination cylinder.
Fig. 2 is the structural representation of lifting rod.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, a kind of rod-pulling type bleeder, is made up of work in combination cylinder and lifting rod, work in combination cylinder comprises outer tube 1 and guide pipe 6, guide pipe 6 is connected on outer tube 1 inwall, guide pipe 6 upper portion side wall axially evenly has many guide channels, outer tube 1 sidewall is provided with pressure release pin 2, pressure release pin 2 lower end is provided with shears snap 3, shearing snap 3 is placed in a passage on guide pipe 6 sidewall, outer tube 1 inwall of pressure release pin 2 upper end has groove, outer tube 1 inwall of shearing snap 3 lower end has groove, back-moving spring 5 is provided with in the groove shearing snap 3 lower end, back-moving spring 5 upper end is provided with grade ring 4, back-moving spring 5 lower end withstands on guide pipe 6 end face, lifting rod by center-pole 7, rotate sliding sleeve 8 and retainer ring 9 and form, rotate sliding sleeve 8 and to be sleeved on center-pole 7 and to be fixed by retainer ring 9, rotate sliding sleeve 8 outer wall and be provided with the convex key of guiding matched with guide pipe 6 sidewall upper channel.
During use, work in combination cylinder along with under oil pipe lower going-into-well, about 30 meters places more than oil well pump usually, lifting rod is along with entering under sucker rod in oil pipe, when lifting rod arrives work in combination cylinder position, enter guide pipe 6, under the effect of guide pipe 6 guide channel, the convex key of guiding rotating sliding sleeve 8 is introduced in guide pipe 6 guide channel, the convex key of guiding rotating sliding sleeve 8 promotes downwards to shear the descending compression reseting spring 5 of snap 3, shearing snap 3 enters in the groove of lower end, shear snap 3 to expand outwardly, lifting rod is made to arrive design attitude (below usual distance work in combination cylinder 20 meters) by work in combination cylinder, shear snap 3 up lower end groove that leaves under back-moving spring 5 acts in addition to reset, enter under completing bleeder.When oil well needs draining, when lift sucker rod drives lifting rod to arrive work in combination cylinder position, enter guide pipe 6, under the effect of guide pipe 6 guide channel, lifting rod is introduced in guide channel, and rotating the convex key of guiding of sliding sleeve 8, upwardly to shear snap 3 up, continues up shearing pressure release pin 2, make the inside and outside communication of oil pipe, realize draining; Lifting rod continues up, enters in outer tube 1 upper recess, shears snap 3 and expands outwardly, make lifting rod by work in combination cylinder, complete bleeder and all work.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
