Abstract
The utility model provides an oil well tubular column bleeder includes: center tube (1), top connection (2), intercommunication cap (3), let out oil pipe (4), pin (5), piston (6), silk braid (7), lower clutch (8), oil well tubular column bleeder be the tubular structure, on center tube (1), both ends are equipped with top connection (2) of external screw thread respectively down, lower clutch (8), the lower part symmetry of top connection (2) is equipped with two intercommunication caps (3), the lower extreme screw thread of intercommunication cap (3) is ined succession and is let out oil pipe (4), let out oil pipe (4) inside be equipped with piston (6), be equipped with pin (5) between oil pipe (4) and piston (6) letting out, silk braid (7) at the bottom threaded connection who lets out oil pipe (4). The utility model is suitable for an oil field beam -pumping unit sucker rod pump oil well tubular column operation draining, self sealing performance is good, and the draining success rate reaches 100%, satisfies oil field work production needs.
Description
Technical field
This utility model relates to oil-field oil pumper sucker-rod pump oil well tubing string operation draining instrument, specifically a kind of oil well pipe bleeder.
Background technology
At present oil-field oil pumper sucker rod pump in operation time, need to lay down the crude oil liquid in tubing string, to prevent crude oil pollution well head and surrounding, at present pumpingh well oil-line pump bleeder mainly has four kinds of modes: one is rotary oil drain, there is the tight draining of self seal, righting slide block rotational resistance does not opens the problem of draining sliding sleeve；
Two is that on pin oil drain under pump, rod string and piston, valve cover is had no progeny, it is impossible to open draining；Three is that pump upper sliding sleeve bleeder rushes open by instrument, and success rate is relatively low only
50%
's.Oil field operation can not be met and produce needs.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, a kind of oil well pipe bleeder of design.
This utility model is realized by following technical proposals:
Oil well pipe bleeder includes: central canal, top connection, connection cap, drain mast, pin, piston, silk braid, lower contact.Described oil well pipe bleeder is tubular structure, central canal upper/lower terminal is respectively equipped with externally threaded top connection, lower contact, the bottom of top connection is arranged with two connection caps, the lower end screw thread of connection cap is ined succession drain mast, piston it is provided with inside drain mast, being provided with pin between drain mast and piston, the bottom thread at drain mast is connected to silk braid.
It is provided with oil-in in connection cap in above-mentioned oil well pipe bleeder.
The top of the drain mast in above-mentioned oil well pipe bleeder is positioned at piston position and is provided with oil leak hole.
Silk braid in above-mentioned oil well pipe bleeder is provided with liquid outlet.
The beneficial effects of the utility model are: being applicable to oil-field oil pumper sucker-rod pump oil well tubing string operation draining, self seal performance is good, and draining success rate reaches
100%
, meet oil field operation and produce needs.
