Description
Technical field
The utility model provides a kind of field produces device, and one contributes to maintaining electric submersible pump quantity-produced electric submersible pump reflux specifically.
Background technology
Along with the prolongation of the time of oil recovery, intermediate zone casing damaged well district water injection well shakes out seriously, if constantly water filling; down-hole pressure can be caused excessive, if be interrupted water filling, electric pump well is underload outstanding problem; and after long-time stoppage in transit; very easily there is holddown accident, frequent start-stop, easily cause the malfunctioning and burn-down of electric motor of protector; cause all will changing or repairing submersible electric pump every year; both caused cost of production to increase, and oil well continuous seepage cannot have been ensured again, affect well yield.And the conventional method solved the problem at present installs electric pump well reflux at well head, realize electric pump well quantity-produced object, but existing reflux complex structure, manufacturing cost is higher, complex operation.
Summary of the invention
In order to solve the problem of the higher and complex operation of existing reflux complex structure, manufacturing cost, the utility model provides a kind of electric submersible pump reflux.This apparatus structure is simple, with low cost, simple to operate.
The technical solution of the utility model is: a kind of electric submersible pump reflux, comprise the valve body with cavity, the lower end of described valve body is fluid inlet, with fluid issuing on sidewall, with axial step hole on the inwall of fluid inlet and fluid issuing, the upper hole of valve body is built-in with valve gap and is fixedly connected with valve body, described valve cover hole be built-in with valve rod and with its threaded engagement, the stomidium of valve gap connects door; The main body of described valve rod is multidiameter, large footpath, middle part section coordinates with the inner hole thread of valve gap, and the lower end of valve rod is cone seals end, forms all linear sealings with the shoulder hole in above-mentioned valve body, top small axle diameter section is supported by the endoporus of door, and the upper end of valve body is stretched out valve gap and pulled mouth for square.
The path section wall of above-mentioned valve rod is fixed with indicating graduation board; Above-mentioned valve body and valve gap, between valve gap and valve rod, be provided with sealing ring.
The beneficial effects of the utility model are: this device is mainly arranged on well head, electric pump well oil pipe is communicated with tubing and casing annular space, when a part of liquid measure in electric pump unit discharge opeing by the import in reflux with outlet from reentering oil sets annular space, another part enters metering room through ground oil return pipeline becomes oil well output, can control capacity of returns easily by the valve rod in this device.In use, first adjust the original oil nozzle of electric pump well, control oily well yield, secondly regulate the backflow valve rod on this device, control the Liquid output being back to oil jacket space, coordinate adjustment by the two, namely can reduce down-hole pressure, can ensure that again electric pump unit continuous and steady operation is produced.

1-valve body in figure, 2-valve gap, 3-valve rod, 4-indicating graduation board, 5-door, 6-sealing ring, 7-sealing ring, 8-fluid inlet, 9-shoulder hole, 10-fluid issuing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this electric submersible pump reflux comprises the valve body 1 with cavity, wherein, the lower end of described valve body is fluid inlet 8, with fluid issuing 10 on sidewall, with axial step hole 9 on fluid inlet 8 with the inwall of fluid issuing 10, the upper hole of valve body 1 is built-in with valve gap 2 and is fixedly connected with valve body 1 screw thread, described valve gap 2 hole is built-in with valve rod 3, and the stomidium screw thread of valve gap 2 is fixedly connected with door 5; The main body of described valve rod 3 is multidiameter, the large-diameter section at middle part coordinates with the inner hole thread of valve gap 2, the lower end of valve rod 3 is cone seals end, circumferential sealing is formed with the shoulder hole 9 in above-mentioned valve body, the endoporus of top small axle diameter section and door 5 is that work claims isometrical and supported by the endoporus of door 5, the upper end of valve body 1 stretch out valve gap and for can with pull that mouth coordinates square.
The path section outer wall of above-mentioned valve rod 3 is with fluted, groove inner bolt is fixed with indicating graduation board 4, and indicating graduation board 4 forms smooth, cylindrical peripheral surface with the path section of valve rod 3, does not affect valve rod 3 relative movement in door 5.
Be provided with sealing ring 6 between above-mentioned valve body 1 and valve gap 2, between valve gap 2 and valve rod 3, be provided with sealing ring 7.
This device is mainly arranged on well head, and electric pump well oil pipe is communicated with tubing and casing annular space, and original position is closed state, and the shoulder hole 9 namely in the conical surface of the cone seals end of valve rod 3 and valve body forms circumferential sealing; During work, the square mouth of pulling blocking valve rod 3 upper end with interior square head wrench pulls valve rod 3 counterclockwise, thus the conical surface on valve rod and the shoulder hole in valve body 9 are separated from, and fluid enters in valve body chamber by fluid inlet 8; Owing to being provided with sealing ring 6 between valve body 1 and valve gap 2, be provided with sealing ring 7 between valve gap 2 and valve rod 3, fluid can only flow out from fluid issuing 10, and fluid issuing 10 is communicated with oil sets annular space, fluid can be made to enter oil sets annular space, thus contribute to electric pump well continuous seepage; And the size of flow is shown by the graduation position of the scale-board 4 on valve rod, and the adjustment stroke of valve rod is limited by door 5, so just make a part of liquid measure in electric pump unit discharge opeing by the import in reflux and export from reentering oil sets annular space, another part enters metering room through ground oil return pipeline becomes oil well output, can control capacity of returns easily by the valve rod in this device.In use, by the original oil nozzle of adjustment electric pump well, oily well yield is controlled, again by regulating the backflow valve rod on this device, controlling the Liquid output being back to oil jacket space, coordinating adjustment by the two, namely can reduce down-hole pressure, can ensure that again electric pump unit continuous and steady operation is produced.
