Description
Technical field
The utility model is related to Oil-Gas Field Development Engineering technology, more particularly to a kind of oil well pump crosses pump well washing apparatus.
Background technology
During oil exploitation, due to the influence of factors, the reservoir sand in reservoir often enters pit shaft, and with
Oil pipe is recycled to ground.In this course, formation sand, because particle diameter is larger, jam can so influence in oil well pump
The efficiency of oil well pump and life-span, can also oil well pump be set to fail when serious.This problem is solved at present, is typically had in actual production
Three kinds of modes:
Reservoir sand is blocked in outside pit shaft by first way, underground sand-prevention using screen casing or other instruments and technology.
However, using which kind of sand control technique and instrument, the sand grains particle diameter of stop has certain scope, has a critical grain size, is less than
The reservoir sand of the critical grain size can enter pit shaft.If during sand control, critical grain size is set into too small, although sand controlling result is more preferable,
But screen casing or other sand preventing tools can be caused easily to be blocked, and small particle sand concentrates near wellbore zone influence stratum infiltration
Rate, so as to influence oil well output.Therefore underground sand-prevention should be " sand control ", " anti-row's combination ", and the sand of bulky grain is stopped
Sand bridge is formed outside pit shaft, fine silt can enter pit shaft by sand bridge gap, ground is returned to crude oil.These fine silts day
The tired jam for also resulting in oil well pump of the product moon.In addition, operating mode of the sand preventing tool in underground is more responsible for and severe, it is used for a long time,
It can be corroded or damage, such sand controlling result will be deteriorated, more accelerate the sand card of oil well pump.Therefore underground sand-prevention measure, only
The sand card of oil well pump can be delayed, but can not fundamentally solve the problem.
The second way, overhauls oil well pump.When discovery oil well pump is by reservoir sand blocked portion, during pump efficiency degradation, it will pump
Pump is proposed from pit shaft, removes reservoir sand and necessary maintenance, then by pump tripping in pit shaft.This measure is although easy and effective,
But it is time-consuming, when particularly the pump overhaul period is shorter, oil well pump tripping in is deeper, the rod tube in well-sinking is frequently played, is not only subtracted
Small effective recovery time of oil gas, influences the oil production of oil well, and has increased considerably operating cost.Therefore maintenance oil pumping
Pump not solves the ideal measure of oil well pump sand card.
In summary, in the several ways provided at present, well mouth of oil well or oil well pump easily occur blocking (upper wellbore temperature
It is relatively low, easily there is oily thick, wax deposition or sand plug), along with reservoir is missed, then being pumped into flushing fluid from oil jacket annular space will be from reservoir
Middle leakage is fallen, it is impossible to which setting up sand card in pit shaft circulation, pump can not also remove.

Structural representation when middle valve plate is closed.As shown in Figures 2 and 3, housing is connected two outer ends with oil pipe string respectively about 1；
Set housing on 3 or multiple attachment screws be connected with valve seat 3, valve module is fixed on housing 1；Set on housing 1
There is a perforate, hole shape is consistent with the shape of valve plate 3, in normal recover the oil, the perforate on housing 1 can accommodate valve plate 3, keep away
Exempt from valve plate 3 and take asphalt channel in oil pipe, reduce crude oil and return out resistance, when needing pump well-flushing, valve plate 3 is closed by flushing fluid
Close, the perforate of housing 1 provides passage of the flushing fluid from oil jacket annular space to oil pipe interior circulation.Valve plate 3 passes through connecting pin 4 and valve seat
2 are connected, and valve plate can be that axle is rotated with connecting pin 4, and two reverse torsion springs 5 are respectively placed in the two ends of connecting pin 4,5 liang of torsion spring
End is separately fixed on valve seat 2 and valve plate 3, in normal recover the oil, is supported valve plate 3, valve plate 3 is in the perforate intracavitary of housing 1,
Normal oil producing operation is not influenceed, and during well-flushing, the pressure of flushing fluid promotes valve plate 3 to rotate, and torsion spring is compressed, and oil pipe leads to stratum
Runner separated so that flushing fluid will not be missed in reservoir, oil jacket annular circulation can be set up, build the pressure washing
Well, after well-flushing is finished, torsion spring 5 is that the valve plate 3 being closed provides restoring force, valve plate 3 is recovered to initial open mode,
Carry out normal oil producing operation.It can be seen that the device can smoothly realize that recovering the oil and cross pump clean-out service freely changes, it is particularly pair
Carrying out pump well-flushing in leakage reservoir has significant effect.
On the basis of above-described embodiment, seal is provided with around the valve plate 3, for inciting somebody to action described in annular space well-flushing
Sealed between valve plate 3 and the side wall of the housing 1.
It is preferred that, the seal is rubber seal.
Generally, the number of the torsion spring 5 is two, is nested with respectively at the two ends of the connecting pin 4, each torsion spring
One end be fixed on valve seat 2, the other end is fixed on valve plate 3.
In a kind of specific implementation, it is preferred that the shape of the valve plate 3 is identical with the shape of the perforate, and institute
The area for stating valve plate 3 is more than or equal to the area of the perforate, can prevent crude oil from leaking to when oil extraction is carried out
Outside pipeline.
The oil well pump that any of the above-described implementation is provided crosses pump well washing apparatus, in normal oil producing operation, in the work of torsion spring
Under, valve plate is to open, i.e., the passage in oil pipe is unimpeded, if necessary to carry out clean-out service, on ground to oil jacket ring
Sky injection detergent remover, valve plate overcomes the support force of torsion spring under the promotion of flushing fluid, is rotated by 90 ° and valve base sealing, isolation leakage
Reservoir is lost, while opening the passage of oil jacket annular space and oil pipe, the circulation canal of oil jacket annular space and oil pipe is set up, you can to clean
Oil well pump on oil pipe.Valve plate is fixed on shell with valve seat combination body further through connecting pin, and housing side is provided with
One special-shaped through hole, main function is to accommodate valve plate, connecting pin and torsion spring (when normally recovering the oil) when valve plate is opened, and is closed in valve plate
When closing (during well-flushing), the passage of oil jacket annular space and oil pipe is set up, the passage of oil pipe and reservoir is closed, cannot be introduced into flushing fluid
Reservoir is missed, pump clean-out service was carried out in the case of reservoir leakage so as to realize, and can realize that pit shaft was followed by this kind of mode
Ring, it is possible to realize that silt is removed by annular space well-flushing mode.
The oil well pump provided by flushing fluid combination such scheme crosses pump well washing apparatus, sets up the oil pumping of pit shaft wash cycles
Pump, is pumped into flushing fluid, flushing fluid can circulate through oil well pump, and oil well pump is cleaned to oil jacket annular space, will be poly- in pump
Long-pending reservoir sand is removed and returns to ground, easy and effective, and the activity duration is shorter.
Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
