Abstract
The utility model relates to a water injecting valve for an electric pump well, which is suitable for a thick oil diluting water injecting electric pump oil extraction well and belongs to a tool under an electric pump oil extraction well in an oil field. The water injecting valve mainly comprises a valve body, a sliding block, a spring, a limit sleeve, a supporting seat, an adjustment nut, a lower joint and a valve ball, wherein a plurality of water injection holes are uniformly distributed on the inner wall of a working cavity of the valve body; a middle hole is formed in the middle of the sliding block; the upper part of the sliding block is positioned by a footstep; the lower part of the sliding block is positioned by the limit sleeve; the sliding block moves in the working cavity; the water injection holes are blocked by the sliding block when the sliding block moves to the upper part; the water injection holes are opened when the sliding block moves to the lower part; the spring is arranged between the sliding block and the supporting seat; the adjustment nut is arranged inside the limit sleeve; and the lower joint is arranged on the lower part of the valve body. By the water injecting valve, forward water injection of an oil extraction pipe column of an electric pump can be realized, so that a cable and a motor can be protected, a pump detection period can be prolonged, and thin oil can be saved.
Description
Technical field
The utility model relates to a kind of electric pump well water injection valve, is applicable to that oil-field thick-oil mixes rare water filling electric pump producing well, belongs to electric motor drive oil pump system down-hole, oil field instrument.
Background technology
At present, the existing electric motor drive oil pump system tubing string of ultra-deep ultra-thick oil mainly is made up of motor, protector, gs-oil separator, centrifugal pump, cable and oil pipe and wellhead assembly.Water filling is for when oil, because the electric pump runner is less, resistance is too big during positive water filling, and can cause the impeller reversing to damage electric pump, therefore can only adopt anti-water filling.During anti-water filling, the thin oil of oil jacket annular space all has been injected into the shaft bottom, after water filling is accomplished, causes stifled pump in order to prevent to return on the viscous crude, needs fill with the oil jacket annular space with thin oil again, because oil jacket annular space volume is bigger, the thin oil waste is serious.During anti-in addition water filling, exist and inject water and wash away cable, the motor cable functional performance is had certain influence, show that through statistics the pump detection period of water filling electric pump well shortens than the pump detection period of non-water filling greatly.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency of the prior art; A kind of electric pump well water injection valve is provided, when oil is replaced in water filling, can adopts the method for positive water filling, avoid injecting water and contact with the direct of motor cable; The protection motor cable; Improve its application life, prolong pump detection period, can practice thrift thin oil again simultaneously.
The technical scheme that the utility model adopts is:
A kind of electric pump well water injection valve of the utility model mainly is made up of valve body, slide block, spring, stop collar, supporting seat, adjusting nut, lower contact, valve ball; Be evenly equipped with a plurality of water injection holes on the inwall of said valve body working chamber; Be provided with interstitial hole in the middle of the said slide block, slide block top is located by step, and the slide block bottom is located by stop collar; Slide block moves in working chamber, and when slide block movement arrived top, water injection hole was by the slide block shutoff, and when slide block movement arrived the bottom, water injection hole was opened.Said spring is installed between slide block and the supporting seat, and said adjusting nut is installed in stop collar inside, and said lower contact is installed in valve body lower portion.
The beneficial effect of the utility model: 1, in existing electric pump pipe column, increase water injection valve, can realize the function of positive water filling.2, after the positive water filling of employing, only need fill with oil pipe, and the volume of oil pipe interior volume specific ratio oil jacket annular space is little a lot, therefore compares with anti-water filling, can practice thrift a large amount of thin oils with thin oil.3, positive water filling has been avoided injecting water and has been contacted with the direct of cable motor, has protected cable and motor, has prolonged pump detection period.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2, a kind of electric pump well water injection valve of the utility model mainly is made up of valve body 1, slide block 4, spring 7, stop collar 8, supporting seat 9, adjusting nut 10, lower contact 11, valve ball 12; Be evenly equipped with a plurality of water injection holes 5 on the inwall of said valve body 1 working chamber 6; Be provided with interstitial hole 3 in the middle of the said slide block 4, slide block 4 tops are by step 2 location, and slide block 4 bottoms are by stop collar 8 location; Slide block 4 moves in working chamber 6, and when slide block 4 moved to top, water injection hole 5 was by slide block 4 shutoff, and when slide block 4 moved to the bottom, water injection hole 5 was opened.Said spring 7 is installed between slide block 4 and the supporting seat 9, and said adjusting nut 10 is installed in stop collar 8 inside, and said lower contact 11 is installed in valve body 1 bottom.
Described water injection valve is installed in the centrifugal pump of existing electric pump pipe column and the centre of oil pipe; After water injection valve assembles; Slide block 4 is under the preset pressure effect of spring 7, and slide block 4 runs to top dead-centre, blocks water injection hole 5; The oil jacket annulus access is closed, thereby can realize mixing normally rare production and positive well-flushing or just annotate technology such as thin oil.When oil is replaced in the needs water filling, drop into valve ball 12 from oil pipe and be seated on the interstitial hole 3 of slide block 4 the downward pathway closure of slide block 4; Build the pressure on top then; When pressure during greater than the preset pressure value of spring 7, valve ball 12 is displaced downwardly to bottom dead centre together with slide block 4, and is as shown in Figure 2; Water injection hole 5 passages are opened, thereby can realize positive water filling.Adjusting nut 10 can regulating spring 7 preset pressure value.
