Abstract
The technical scheme that this utility model is taked by the above-mentioned technical problem of solution is: a kind of oil well pump blanking plug, it is connected with oil-well pump bottom, it includes shell, push rod and blocking device from top to bottom it is provided with in shell, the top of push rod contacts with the valve ball of the standing valve assembly of oil-well pump bottom, and making the valve ball of the standing valve assembly of oil-well pump bottom be in normally open, push rod sidepiece is connected with shell by cutting off pin, is connected with described blocking device bottom push rod.Before going into the well, first passing through push rod by valve ball jack-up, make standing valve be in normally open during going into the well, blocking device plays the effect sealing and stopping foreign material during going into the well；When under oil well pump to operating position, by ground pressure system, will cut off pin and cut off, blocking device and push rod fall into shaft bottom, and valve ball enters operating position and starts working, and during finally realization prevents blowout and lower pump, shaft bottom foreign material enter the purpose of pump barrel.
Description
Technical field
This utility model belongs to oil drilling field, is specifically related to a kind of oil well pump blanking plug.
Background technology
Jianghan Oil-field exploitation middle and late stage, all there is the problems such as pit shaft is dirtier, shaft bottom foreign material are more in many oil wells, under enter to take out
During oil pump, the problem that foreign material entrance pump barrel causes oil well pump to lose efficacy happens occasionally, and the lighter causes extending the activity duration, sternly
Cause during weight repeating operation.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of oil well pump blanking plug, it is possible to realize preventing blowout and
During lower pump, shaft bottom foreign material enter the purpose of pump barrel.
The technical scheme that this utility model is taked by the above-mentioned technical problem of solution is: a kind of oil well pump blanking plug, and takes out
Connect bottom oil pump, it is characterised in that: it includes shell, is from top to bottom provided with push rod and blocking device, the top of push rod in shell
Portion contacts with the valve ball of the standing valve assembly of oil-well pump bottom, and the valve ball of the standing valve assembly of oil-well pump bottom is in often
Open state, push rod sidepiece is connected with shell by cutting off pin, is connected with described blocking device bottom push rod.
By such scheme, described shell is threaded connection with the standing valve assembly of oil-well pump bottom.
By such scheme, described blocking device is piston, and piston base connects back of the body cap.
By such scheme, described outer casing inner wall is provided with back-up ring, and back-up ring is provided with gland, and described push rod is by described
Cut off pin to be connected with back-up ring.
The beneficial effects of the utility model are: before going into the well, and first pass through push rod by valve ball jack-up, make standing valve during going into the well
Being in normally open, blocking device plays the effect sealing and stopping foreign material during going into the well；When arriving working position under oil well pump
When putting, by ground pressure system, will cut off pin and cut off, blocking device and push rod fall into shaft bottom, and valve ball enters operating position
Starting working, during finally realization prevents blowout and lower pump, shaft bottom foreign material enter the purpose of pump barrel.
Accompanying drawing explanation
Fig. 1 is the axial section of this utility model one embodiment.
1-push rod, 2-gland, 3-back-up ring, 4-cuts off pin, 5-piston, 6-shell, and 7-carries on the back cap, 8-standing valve assembly, 9-
Valve ball.
Detailed description of the invention
Below in conjunction with instantiation and accompanying drawing, this utility model is described further.
This utility model provides a kind of oil well pump blanking plug, as it is shown in figure 1, be connected with oil-well pump bottom, it includes shell
6, from top to bottom it is provided with the valve of the standing valve assembly 8 of push rod 1 and blocking device, the top of push rod 1 and oil-well pump bottom in shell 6
Ball 9 contacts, and makes the valve ball 9 of the standing valve assembly 8 of oil-well pump bottom be in normally open, and push rod 1 sidepiece passes through break pin
Nail 4 is connected with shell 6, is connected with described blocking device bottom push rod 1.
Preferably, described shell 6 is threaded connection with the standing valve assembly 8 of oil-well pump bottom.
It is further preferred that described blocking device is piston 5, connects bottom piston 5 and have back of the body cap 7.Blocking device also may be used
To be other the device that can seal, and on oil field, piston 5 is optimal structure, can ensure that when maintaining static
And the sealing between shell 6, thus avoid blowout and stop foreign material；To cut off pin 4 when cutting off, piston rod again can be rapid
Fall into shaft bottom under gravity, it is ensured that the normal work of oil well pump.
Refining further, described shell 6 inwall is provided with back-up ring 3, and back-up ring 3 is provided with gland 2, and described push rod 1 leads to
Cross described pin 4 of cutting off to be connected with back-up ring 3.This structure can be when cutting off pin 4 and cutting off, it is ensured that shell 6 is not damaged,
Shell 6 can also continue complete to be connected to oil-well pump bottom, carries out recycling next time.
Under pump, blanking plug is the effective tool preventing blowout and shaft bottom foreign material from entering pump barrel, it should be noted that following thing in using
: 1, install well control device, under enter pumping pipe string, under before complete tubing string, forbid pressure testing, the pump testing of pouring water.2, complete rod string under
After, visit pump three times, calculate the degree of depth, carry out mark, above carry sucker rod 2～3, with the special good back seat of side's card card in tubing hanger
On, install well head and suppress pin is cut off, and pressure testing；Enter down sucker rod, polished rod, to good dead space, examination is taken out normal, complete
Well.
