More than the oil well pump of higher level's pipe aperture.At this moment the plunger of oil well pump can only be with pump barrel tripping in or proposition simultaneously.Sucker rod and post
On-off connector is installed between plug, achieves a butt joint or disengages by being axially moved.
, it is necessary to block pipeline under pump during well workover, completely cut off the inside and outside pressure source of pipeline.Avoid in work progress, underground
Medium sprays, and causes energy waste, environmental pollution, or security incident.
It can meet requirements above currently without similar products, typically use well killing fluid during well workover, pour into, limit out of oil pipe
Down-hole pressure.Duty cycle is grown, and cost is high.
Utility model content
The purpose of this utility model is to provide a kind of down-hole plugging device of uncoupling plunger tubing pump snubbing serving, its
It is rational in infrastructure, dependable performance, down-hole pressure can be repeatedly blocked, the workover treatment of actuating oil-pumping unit, oil pipe with pressure can be from well
Lower blocking pipe, completely cut off pipe external and internal pressure, save the energy, environmental protection, improve safety coefficient, improve production efficiency, reduce into
This.
What the purpose of this utility model was realized in：A kind of down-hole plugging dress of uncoupling plunger tubing pump snubbing serving
Put, including the sucker rod in the tubing string on pump is connected to plunger pump, is connected to release in the lower port of tubing string on pump
Pipe is put, the lower port for discharging pipe is connected to pump barrel, and the lower end in pump barrel sets seal boss, and pump barrel is connected to oil pipe under pump
Post, the lower end closed of tubing string under pump, coordinates the plunger pump being arranged in pump barrel, its upper end is connected to take out by plunger on-off connector
Beam hanger, the lower end of plunger pump are connected to standing valve, the block machine front cover and seal boss of standing valve upper end by standing valve on-off connector
It is engaged, the lower end of standing valve is connected to inner tube assembly by inner tube on-off connector, and tubing string internal upper part is set spacing under pump
The internal diameter of land is less than the external diameter of inner tube assembly inner tube.
Operation principle of the present utility model：
1, when tubing string is installed, plugging device is in sealed condition, plunger and fixed valve assembly discharge pipeline section in pump.
Tubing string installs, it is possible to pressure testing, after checking sealing is qualified, then transfers rod string.
By plunger on-off connector top, it is connected on rod string, transfers together.
Rod string is encountered assembly for plunger, fixed valve assembly, inner tube assembly together, plunger on-off connector, standing valve uncoupling
Device, inner tube on-off connector achieve a butt joint simultaneously.
Fixed valve sealing surface 1 and the fitted seal of sealing surface 2, while inner tube comes downwards to open position.
Here half meter of sucker rod is above carried, then is transferred, opens standing valve on-off connector.Dead space can be adjusted, starts to pump.
2, during oil recovery, plugging device is in open mode, and the fluid outside tubing string can enter, and inside and outside medium can pass through
Oil inlet comes in and goes out, and can normally pump；
3, before well workover, first transfer sucker rod, dock standing valve on-off connector, then above carry, standing valve by inner tube on-off connector, on
Put forward inner tube.
The sealing ring at two in inner tube, under pump during tubing string oil inlet both sides, plugging device is closed, oil
Tubing string is inside and outside to be completely cut off.
Continue above to carry, inner tube reaches limiting stand, on-off connector release, and standing valve and plunger are up to release pipeline section simultaneously.Again
Above propose sucker rod, the release of plunger on-off connector.
After pressure testing checking sealing, the work-over operations such as sucker rod, oil pipe can be above carried；
Continue above to carry sucker rod, miscellaneous part is all stayed in pump barrel.
The utility model is rational in infrastructure, dependable performance, and down-hole pressure can repeatedly be blocked by realizing, with pressure to remove oil pumping
The workover treatment of bar, oil pipe, realize and can completely cut off pipe external and internal pressure from down-hole plugging pipeline, saved the energy, protected ring
Border, safety coefficient is improved, improve production efficiency, reduce cost.
