Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
A kind of mining device of electric submersible oil reciprocation pump on Oil/gas Well, including circulation fluid outlet 1, gate gurgle valve 2, ball-and-seat
3rd, standing valve 4, plunger strike-off steel bowl 5, travelling valve 6, plunger 7, linear electric motors 8, sand setting tail pipe 9,3 inches of oil pipes 10,1.9 inches
Pipe 14 by oil pipe 11, outer appearance sand seating nipple 12, interior pump barrel 13 and sand setting, described linear electric motors 8 and passes through pipe 14 by sand setting
Plunger pump, sand setting tail pipe 9 are connected, and plunger pump includes outer appearance sand seating nipple 12, interior pump barrel 13, plunger 7, plunger and strike-off steel bowl
5th, travelling valve 6, standing valve 4；The formation of pipe 14 one by the described bottom lock of sand setting tail pipe 9 and outer appearance sand seating nipple 12 and sand setting
Individual closed annular space；Standing valve 4 and ball-and-seat 3 are set on plunger 7, and when linear electric motors 8 are up, the well liquid in plunger 7 passes through
Open standing valve 4, ball-and-seat 3 and enter 3 inches of oil pipes 10 and 1.9 inches of oil pipes 11, outer tube valve and circulation fluid outlet 1 is then in
Close；When linear electric motors 8 are descending, ball-and-seat 3, standing valve 4 are then closed.
When linear electric motors 8 are up in process of production, the well liquid in plunger 7 is entered by opening standing valve 4, ball-and-seat 3
Enter double concentric tubes（3 inches of oil pipes 10 and 1.9 inches of oil pipes 11；）Give rise to ground well head.Now outside 24 outer tube valves 1. and 25.
Tube valve is closed.22. in tube valve 1 open toward oil transportation, feed channel conveying crude oil.The ball-and-seat 3, solid when linear electric motors 8 are descending
Determine valve 4 to close.Well liquid enters to wait in plunger 7 by Pump Suction Nozzle 8 to be lifted next time.Sub-sand in the middle part of well liquid lifting process
As well liquid gives rise to ground, heavy sand then enters linear electric motors by pipe 14 by outer appearance sand seating nipple 12 and sand setting
In 8 tail pipes.Necessarily draw after sand is heavy full by the annular space in pipe 14 and tail pipe 11 by outer appearance sand seating nipple 12 and sand setting
Dusting, which is buried, to be caused sand card or loses pump efficiency.Now opening outer tube valve 25. using ground circulating pump will be followed using ground circulating pump
Ring liquid is entered through from the circulation fluid outlet 1 of 1.9 inches of oil pipes 11 from 3 inches of oil pipes 10 enters the 1.9 inches of outflow of oil pipe 11 ground
Face（Backwash）.Or utilize ground circulating pump that circulation fluid is entered into 3 inches of oil by circulation fluid outlet 1 from 1.9 inches of oil pipes 11
Pipe 10 flows out ground from 3 inches of oil pipes 10（Just wash）.Untill being free of sand in well liquid.Thus effectively solve Oil/gas Well
Sand card, the sand occurred buries problem.Realize and take sand oil pumping technique.Realize the normal production of shake out producing well and gasser.
The main advantage of the present invention is：
1. take full advantage of electric submersible oil reciprocation pump standing valve realizes the clean-out service in oil pipe the characteristics of upper end
Excessive well-flushing pressure is not needed clean-out service is become safety work.
2. take full advantage of the straight reciprocating motion principle of electric submersible oil reciprocation pump linear electric motors 8.
3. in order to prevent sand setting from blocking plunger 7, strike-off steel bowl provided with one in the upper end of plunger 7, steel bowl is close to by elastic force
On the interior wall of pump barrel 13, prevent sand from entering the gap of plunger 7 and interior pump barrel 13.After plunger 7 reaches up stroke end points, steel bowl
The sand scraped sinks to the annular gap of outer appearance sand seating nipple 12 and interior pump barrel 13, until sinking to tail pipe.
4. tripping in concentric double pipe post in well, when oilwell produced fluid amount is very low, it is impossible to take sand out of pit shaft by oil well liquid measure
When, using the original jet pump flow in ground, start ground face-pumping, power fluid is from 3 inches of oil pipes 10 and 1.9 inches of annular spaces of oil pipe 11
Enter well, to the upper end of gate gurgle valve 2, enter 1.9 inches of oil pipes 11 from circulation fluid outlet 1 and return to ground, can be anti-by the sand setting in oil pipe
Go out pit shaft.Circulated in technique using on pump, ground face-pumping need to only overcome the water resistance of flow, and pressure is not high, safety work.
