Abstract
The invention discloses a water injection flow controller which belongs to the technical field of petroleum machinery. The round inner hole of an annular valve holder is provided with a conical incline; the valve holder is pressed and fixed in an inner cavity of the controller through a puller sleeve; a valve core is fixed at the front end of a guide sleeve; the rear end of the guide sleeve is matched with a screw rod by threads; the outer end of the screw rod is fixed with a handwheel; the valve core is formed by the combination of a cylinder with an incline and a conical body; the cylinder with the inclined of the valve core can be inserted into the round inner hole of the valve holder; the incline of the conical body of the valve core is contacted, matched and sealed with the incline of the conical inner hole of the valve holder; and the screw rod is rotatably matched with a shell through a rotary bearing and a compressing cap. The water injection flow controller has the beneficial effects that: water passing flow is adjusted; the conical hole of the valve holder and the conical body of the valve core realize the stop function; therefore, the water injection flow controller has the advantages of excellent impurity pass and long service life; moreover, all the spare parts in a bearing cavity are arranged from a water inlet end; and the hidden safety trouble of pressing out the spare parts from the sealing end of the screw is avoided.
Description
Technical field
The invention belongs to the petroleum machinery technical field, relate to of the improvement of a kind of oil field at distributing room for water injection regulation and control individual well injection flow device.
Background technology
In oilfield development process, for keeping strata pressure, make steady output of oilwell, generally adopt water injection method to replenish strata pressure at present and reach the stable yields purpose.Because the difference of each well water injection rate, the injection flow majority of every mouthful of well is regulated and control at distributing room for water injection, and the oil-field flooding flow uses high pressure sluice valve or throttle valve control injection flow at distributing room for water injection now.Use high pressure sluice valve control water injection rate exist application life short, adjust water injection rate shortcoming such as waste time and energy, valve is not closed completely after damaging, it is frequent to cause changing valve, increases trouble to production management, has also strengthened cost of production simultaneously.Use choke valve to result in blockage easily water injection rate to occur and reduce phenomenon gradually owing to conical valve seat and spool gap are little, for keeping the regulation water injection rate, need often to adjust valve discharge area size and control water injection rate, can not guarantee that water injection rate is stable, increase intensity of workers again.Form because valve and valve gap are two bodies, have unsafe factor.
Summary of the invention
The objective of the invention is: a kind of injection flow regulation device is provided, this device has to be regulated and by the effect of individual well injection flow, and long service life, impurity trafficability characteristic are good, because this crust of the device is an one, and part is all packed into from water inlet in the pressure pocket, has improved safety in utilization.
Technical scheme of the present invention is: the circular inner hole of ring-shaped valve seats has tapered slope, valve seat is fixed in the device inner chamber by the tight sleeve roof pressure, spool is fixed on the fairlead front end, the fairlead rear end cooperates with threads of lead screw, the external end head and the handwheel of leading screw are fixed, spool is combined by band surface cylinder body and bullet, its band surface cylinder body can insert the circular inner hole of valve seat, the inclined-plane of spool bullet contacts fitted seal with the inclined-plane of valve seat cone-shaped inner hole, and leading screw is rotatably assorted with clamping cap and housing by vicarious.
Whole housing is a metal integral, and the whole parts in the pressure pocket are all packed into from the water inlet end.
External end head at housing is provided with lockhole, and the anti-rotation lock pin is installed on the handwheel.
The invention has the beneficial effects as follows: 1, because valve seat takes straight circular port and bellmouth to form, spool is taked to form with the cylinder on inclined-plane and bullet, the band surface cylinder body of spool inserts the circular port diverse location of valve seat and realizes the water amount adjusting, the bellmouth of valve seat and the bullet of spool are to realize by effect, therefore both had good impurity trafficability characteristic, had long-life advantage again.2, since the accessory size of this device in chamber all greater than leading screw sealed end size, so the interior whole parts of pressure pocket all pack into from the water inlet end, do not have the potential safety hazard that is forced out from the leading screw sealed end.
Description of drawings:
Fig. 1 is the structure sectional view of closed condition of the present invention.
Fig. 2 is the structure sectional view of opening of the present invention.
The specific embodiment
Embodiment 1
Below in conjunction with accompanying drawing the present invention is described further:
As shown in the figure, the 1st, tight sleeve, the 2nd, sealing ring, the 3rd, valve seat, the 4th, spool, the 5th, fairlead, the 6th, directed pin, the 7th, leading screw, the 8th, vicarious, the 9th, seal, the 10th, clamping cap, the 11st, handwheel, the 12nd, acorn nut, the 13rd, anti-rotation lock pin, the 14th, housing.
Valve seat 3 takes straight circular port and bellmouth to form, be fixed in the housing 14 with tight sleeve 1, spool 4 is taked to form with the cylinder on inclined-plane and bullet, spool 4 is combined into one with fairlead 5, fairlead 5 is threaded with leading screw 7, and the water intake end aperture size of housing is big, and leading screw sealed end aperture size is little, accessory size in this device chamber is packed into from the water inlet end all greater than leading screw sealed end size.Handwheel heart portion is provided with and prevents rotating mechanism voluntarily after handwheel is vibrated---and anti-rotation lock pin, an end of stop pin can insert housing end face lockhole intraocular and prevent that handwheel from rotating.The band surface cylinder body of spool inserts the circular port diverse location of valve seat and realizes different water amounts, and the bellmouth of valve seat and the bullet of spool are to realize blocking current to use.For improving the accuracy of adjusting water injection rate, fairlead adopts fine pitch to cooperate with leading screw, and water injection rate is easily realized fine setting.
During operation injection flow regulation device, clockwise rotating handwheel is to close, rotate counterclockwise and be out, because area change that the leading screw of this device and fairlead are fine pitches when cooperating leading screw rotation one to enclose between valve seat and the spool is less, like this, help trace adjustment water amount and reach waterflooding requirement, use gate valve adjusting water amount time saving and energy saving than present oil field.Valve seat and spool adopt high-abrasive material, and long service life reduces the production maintenance cost.
