Description
Art
The utility model relate to down-hole oil production equipment, more particularly to a kind of special separate extracting pump.
Background technology
During crude oil extraction, the situation that double-deck oil is distributed up and down is frequently encountered, being exploited using common oil well pump is needed
Twice, and there is interlayer interference in lower pump, now double-deck exploitation simultaneously can improve operating efficiency and economy, can improve
Oil production, reduces interlayer interference.
Co-producing pump can realize double layer commingled production, but existing co-producing pump complex structure, cumbersome, high processing costs,
Pump detection period is long.
The content of the invention
The utility model passes through problem above, there is provided a kind of rational separate extracting pump structure, plays double-deck oil and exploits simultaneously
Effect, improve production efficiency, simple structure, good economy performance.
It is to reach above-mentioned purpose the technical solution adopted in the present invention：Including connecting rod, outer plunger, inner plunger is outer travelling
Valve, upper pump barrel, outer standing valve, interior travelling valve, lower pump barrel, packer, interior standing valve, sleeve pipe, described connecting rod with
Outer plunger is connected with one heart, and upper pump barrel is connected with lower pump barrel by the way that welding manner is concentric, and lower pump barrel is connected with packer, solid connecting rod
Concentric with inner plunger to be connected, outer plunger is connected with inner plunger by the way that solid connecting rod is concentric, and it is outer that inner plunger bottom is provided with a pair of bias
Travelling valve, upper pump barrel bottom is provided with a pair eccentric outer standing valves, and sleeve pipe is concentric with packer to be connected.
This separate extracting pump simple structure, easy construction, good reliability, good economy performance can reach point effect adopted, adaptability
It is good.

Specific embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of special separate extracting pump, including connecting rod (1), outer plunger (2), inner plunger (3), outer travelling valve
(4), upper pump barrel (5), outer standing valve (6), interior travelling valve (7), lower pump barrel (8), packer (9), interior standing valve (10),
Sleeve pipe (11), described connecting rod (1) is concentric with outer plunger (2) to be connected, and upper pump barrel (5) is same by welding manner with lower pump barrel (8)
The heart is connected, and lower pump barrel (8) is connected with packer (9), and solid connecting rod (1) is concentric with inner plunger (3) to be connected, outer plunger (2) with it is interior
Plunger (3) is connected with one heart by solid connecting rod (1), and inner plunger (2) bottom is provided with a pair eccentric outer travelling valves (4), upper pump barrel
(5) bottom is provided with a pair eccentric outer standing valves (6), and sleeve pipe (11) is concentric with packer (9) to be connected.Upper pump barrel (5) directly connects
Oil pipe is connect, connected mode is threaded connection；Packer (9) by upper and lower oil reservoir packing open, be critical component of the present utility model it
One；Outer plunger (2) is concentric with inner plunger (3) to be installed, and the volume that two plungers are surrounded is equal；Connecting rod (1) at the same with outer plunger (2) and
Inner plunger (3) is connected, and when connecting rod (1) moves up and down, can simultaneously drive outer plunger (2) and inner plunger (3) upper and lower motion, while
Realize two changes of annular seal space volume so that the change of build-up of pressure, this process be take out, the basis of oil extraction liquid；Upper pump barrel (5)
It is connected by way of welding with lower pump barrel (8)；Lower pump barrel (8) is designed to " convex " font, for the exploitation of upper oil reservoir fluid is provided
Feed pathway；There is certain interval between outer plunger (2) and lower pump barrel (8), there is gap between inner plunger (3) and upper pump barrel (5),
Ensure that outer plunger (2) can move up and down in lower pump barrel (8), inner plunger (3) can move up and down between upper pump barrel (5), otherwise
Holddown accident can be made；There is leakage fluid dram on outer plunger (2) and inner plunger (3) top, are easy to discharge opeing.
Connecting rod (1) is solid connecting rod, connection outer plunger (2) and inner plunger (3), and connecting rod (1) and outer plunger (2) and interior
Plunger (3) is connected with one heart, convenient processing.
Connecting rod (1) is moved upwards in upstroke, while drive outer plunger (2) and inner plunger (3) to move upwards, under two plungers
The annular seal space volume increase of side, pressure reduction, now interior standing valve (10) and outer standing valve (6) opening, realize two-layer oil
While drawing liquid；During down stroke, connecting rod (1) drives outer plunger (2) and inner plunger (3) to move downward, two plungers lower section annular seal space
Volume reduces, pressure increase, and outer travelling valve (4) and interior travelling valve (7) are while open, the fluid in annular seal space is respectively enterd
Two plungers, realize discharge opeing.
Fluid in inner plunger (3) can be discharged in outer plunger (2) in down stroke, and connecting rod can be simultaneously passed through in upstroke
(1) drive outer plunger (2) is moved upwards and ground is arrived in lifting, and double-deck oily the dividing of realization is adopted.
The utility model devises a kind of cleverly separate extracting pump by careful research and discussion, can realize double-deck oil simultaneously
Exploitation, improves production efficiency, it is to avoid interlayer interference, simple structure, good economy performance, good manufacturability.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all any changes done based on the utility model or modification belong to the claimed scope of the utility model.
