Description
Technical field
The utility model is the downhole tool of oilfield production, especially a kind of novel and multifunctional suction unit.
Background technology
Currently, oil well declines with oil recovery year by year, strata pressure, escaping gas cannot be arranged effectively from fluid
Go out, gas be influence pumping efficiency of oil pump the main reason for one of, especially more gas wells on oil well pump influence bigger because gas into
Enter in pump, so that the delay of oil well pump oil inlet valve is opened, be even switched off, to reduce pumping efficiency of oil pump, cause under oil well output
Drop,；Existing air trap device has the following problems that 1, gas-tight efficiency is low in production, cannot give full play to the potential of deep well pump；
2, solid phase particles can not be detached, solid phase enters the fragile deep well pump of deep well pump；3, part air trap device, outside separating mechanism
Dew, easy to wear, the service life is shorter.
Invention content
The purpose of this utility model is to provide a kind of also to have sand control, gas-tight in addition to having the function of pumping function, from
And pumping efficiency is improved, extend the service life of the device, increases the novel and multifunctional suction unit of oil recovery economic benefit.
The technical solution of the utility model is：
Novel and multifunctional suction unit, which is characterized in that including suction assembly and gs-oil separator, suction assembly lower end is logical
Upper connector connection gs-oil separator is crossed, gs-oil separator includes top connection, and top connection upper end connects connecting tube, top connection lower end
Outer tube is connected, outer tube top is provided with sieve pore, and top connection lower end is also associated with internal core pipe, and internal core pipe is located in outer tube, interior
Flight is provided on portion's core pipe excircle, flight is located at the lower section of outer tube sieve pore, and internal core pipe is arranged below flight
There are inlet opening, internal core pipe lower end to seal, wire-wrapped screen is cased with outside internal core pipe lower part, outer tube lower end connects valve seat, valve
Spring is fixed in seat, spring upper end compresses valve ball, and valve seat outer wall connects lower connector, and plug is arranged in lower connector lower end.
The top connection top is provided with inclined hole, and inclined hole is connected to annulus and the sky outside outer tube between outer tube and internal core pipe
Between.
The wrapping wire of the wire-wrapped screen is made of stainless steel, and wire-wrapped screen cross sectional shape is T-type, gap 0.02
To 0.5 centimetre.
The utility model uses in the oil well containing sand, gassiness, and in aspiration procedure, suction assembly completes oil pumping function,
Gs-oil separator realizes that gas, sand, liquid are automatically separated, and realizes sand control, the function of gas-tight extends the dress to improve pumping efficiency
The service life set increases oil recovery economic benefit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
15 outer tube of suction assembly 2 upper connector, 3 gs-oil separator, 4 top connection, 6 inside core pipe 7

Specific implementation mode
Novel and multifunctional suction unit, including suction assembly 1 and gs-oil separator 3,1 lower end of suction assembly pass through upper connection
Pipe 2 connects gs-oil separator 3, and gs-oil separator 3 includes top connection 4, and 4 top of top connection is provided with inclined hole 8, and inclined hole 8 is connected to outer tube 5
Annulus and the space outside outer tube 5 between internal core pipe 6.
4 upper end of top connection connects connecting tube, and 4 lower end of top connection connects outer tube 5, and 5 top of outer tube is provided with sieve pore 7, above connects
First 4 lower end is also associated with internal core pipe 6, and internal core pipe 6 is located in outer tube 5, and flight 9 is provided on 6 excircle of internal core pipe,
Flight 9 is located at the lower section of 5 sieve pore 7 of outer tube, and internal core pipe 6 is provided with inlet opening, 6 lower end of internal core pipe below flight 9
It seals, is cased with wire-wrapped screen 10 outside 6 lower part of internal core pipe, the wrapping wire of wire-wrapped screen 10 is made of stainless steel, is unlikely to deform, wrapping wire
10 cross sectional shape of screen casing is T-type, and gap is 0.02 to 0.5 centimetre, is not easy to plug, intensity is good；Blocking can be removed
Gap；Reduce secondary pollution.
5 lower end of outer tube connects valve seat 11, spring 13 is fixed in valve seat 11,13 upper end of spring compresses valve ball 12, all
Your 11 outer wall of seat connects lower connector 14, and plug 15 is arranged in 14 lower end of lower connector.
The operation principle of the utility model is：Fluid is entered by 5 aperture of device outer tube in the present apparatus, realizes gas, sand, liquid
It is automatically separated, the gas isolated is discharged into oil jacket annular space by top inclined hole 8；The sand isolated is sunk in tail pipe or oil well；Point
Enter pumping unit from internal core pipe 6 from rear fluid.Since liquid enters internal core pipe 6 through flight 9, it is clear to may also function as self
The effect washed washes away the sand of 10 remaining of wire-wrapped screen.There are three zones in the process, is oil pumping respectively, gas-tight, prevents
Sand function.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
