Embodiment
The technical solution of the utility model is elaborated in conjunction with accompanying drawing, but the utility model be not limited only to it is following
Embodiment.
Referring to Fig. 1 and 2, the multimedium integration injection allocation apparatus of the present embodiment includes anti-return and tells component 2, injection allocation supervisor 3, goes out
Hydropexis disk 4, regulation activity valve module 5.Wherein injection allocation is responsible for 3, water outlet fixed disk 4 and regulation activity valve module 5 from top to bottom
Connection forms injection allocation main body.In use, by the top of injection allocation main body by top connection 1 and other pipeline communications, under the connection of bottom
Joint 6, it is arrived by injection allocation layer with lower after other pipeline communications by lowering-in operation construction, corresponding one of an injection allocation layer matches somebody with somebody filling
Put, isolated between different injection allocation layers using packer, realize multi-zone flow regulating.
The present embodiment it is anti-return tell component 2 be sleeved on injection allocation supervisor 3 outside, valve is told using anti-return of sleeve type structure, its
Stratum and injection allocation supervisor 3 can be separated, when the pressure on stratum is more than pressure in injection allocation supervisor 3, stratum water, gas will not return tell to
In note supervisor 3；And during normal injection allocation, in injection allocation supervisor 3, injection allocation pressure is more than strata pressure, and compression, which is returned, tells valve spring, prevents returning telling
Valve moves up, you can normal injection allocation.The upper end of injection allocation supervisor 3 is connected with top connection 1, is machined with its tube wall and is run through from top to bottom
Bridge-type annular flow channels d, to ensure not influenceing the normal injection allocation of other layer of position when envelope is tested in injection allocation.3 are responsible in injection allocation
Bottom side of the wall on avoid bridge-type annular flow channels d place offer injection allocation outlet c, for injection allocation fluid to be exported.
Internal thread is machined with the lower port of injection allocation supervisor 3, is threadedly connected with water outlet fixed disk 4.
Referring to Fig. 3 and 4, described water outlet fixed disk 4 is the hollow dish structure of a stepped construction, with injection allocation supervisor 3
The top ladder external diameter of connection is smaller, and internal diameter is identical with the internal diameter of injection allocation supervisor 3, processing and external screw thread and injection allocation in its outer surface
The internal thread matching of 3 lower ports is responsible for, is threadably linked into an integrated entity.It is connected in water outlet fixed disk 4 and injection allocation supervisor 3 upper
Portion ladder top is machined with Circular buffer groove a, for fluid to be collected before output.The lower end of corresponding water outlet fixed disk 4
External diameter is larger, forms hierarchic structure with its top, that is, forms lower step, processed in the lower step side wall of water outlet fixed disk 4
Have two penetrate from top to bottom cross chute b, this crosses the special-shaped groove that chute b is made up of rhombus groove and U-lag, along counterclockwise
Direction, chute b U-lag is crossed on the right side of rhombus groove, chute b section is formed by small progressively to one to diminish again greatly
Variable cross-section, it is easy to low discharge to be precisely controlled.Cross the enlarging groove that chute b can also be circumferencial direction, or other variable cross-sections is different
Shape groove, and the number for crossing chute b can also be 1 either 4 or 6, is preferred with even number, and on same circumference
Even distribution, ensure that pressure distribution is uniform on same section and water outlet is uniform.Pass fluid through chute b lower end enter after under
Collect on and in Circular buffer groove a, when injection allocation is responsible for 3 internal pressures and is more than external pressure, fluid is filled with anti-return and tells component 2
Sealing cavity in, force the anti-spring-compressed for returning and telling component 2, anti-return is told the overcoat of component 2 and moved up, the injection allocation of injection allocation supervisor 3
C and ft connection are exported, through injection allocation outlet c outputs under the fluid that cache slot a collects pressure effect internally, ensures that injection allocation is suitable
Profit；On the contrary, when injection allocation is responsible for 3 internal pressures and is more than external pressure, anti-to return the spring recovery for telling component 2, anti-return tells component 2
Overcoat moves down, and injection allocation outlet c closure effectively prevents from returning telling.
Need to further illustrate, in order to ensure fluid flow be precisely controlled on the basis of pressure it is evenly distributed, cross chute b's
U-lag width should be less than the width of rhombus groove, and be the 1/5~1/2 of rhombus groove Breadth Maximum.
Regulation activity valve module 5 is connected with the lower end of water outlet fixed disk 4, referring to Fig. 5, the regulation activity valve module 5 wraps
5-1 containing valve body, regulation movable valve seat 5-2 and regulation movable spring 5-3, valve body 5-1 are responsible for by water outlet fixed disk 4 and injection allocation
3 connections, offer multiple bar holes in valve body 5-1 side wall, by internal and valve body 5-1 ft connections, valve body 5-1 top
Turned up the flange to be formed and be made up of multiple blades at edge, and disk seal structure, flange are used between the flange and water outlet fixed disk 4
Blade number be 3~6, and uniform on same circumference, the width of a blade and an adjacent blade in circumferencial direction
Do not wait and a blade and a relative blade are symmetrical on circle center.Regulation moving valve is installed in valve body 5-1 bottom
Seat 5-2, regulation movable valve seat 5-2 are that steel ball rolls valve seat, and regulation activity bullet is set with regulation movable valve seat 5-2 bottom
Spring 5-3.
In order to adapt to the performance of various injection allocation fluids, the service life of extension fixture, above-mentioned injection allocation main body and anti-return are told
Component 2 is made of inconel718 alloy materials, and it has preferable high temperature resistant, corrosion resistance characteristic, makes entirely to match somebody with somebody filling
Put and disclosure satisfy that water distribution, the requirement of distribution and service life are grown.
In order to ensure the requirement of the relatively high sealing of whole injection allocation apparatus, above-mentioned injection allocation supervisor 3 with it is anti-return tell component 2 it
Between, between injection allocation supervisor 3 and water outlet fixed disk 4, the junction of injection allocation main body and external pipe be mounted on FFKM sealing
Circle, it both has preferable high temperature resistant, acid-alkali-corrosive-resisting performance and vacuum enhancing, and good sealing effect, is directed to when special
For the preferable gas of mobility, its air-tightness is good compared with usual silicone rubber sealing ring.
In use, after arriving injection allocation layer below the injection allocation apparatus, generally first carry out testing envelope, whether the injection allocation in testing well reaches
Expected effects.When being allocated with fluence, integrated measurement and adjustment instrument is transferred to pit shaft with cable, integrated measurement and adjustment instrument will currently match somebody with somebody
Fluence is sent into ground system by cable and shown, ground is as requested to send instructions with fluence to downhole measurement adjusting instrument, measurement and adjustment instrument
Regulation motor, which rotates, drives the valve body 5-1 of regulation activity valve group to rotate, because vane type flange rotational angle is different, corresponding top
Water outlet fixed disk 4 crosses that chute b apertures are different, and so as to which adjust this layer of position matches somebody with somebody fluence, the injection allocation flow after regulation is passed simultaneously
It is sent to ground system to show, such as not up to demand matches somebody with somebody fluence, can continue to adjust, and matches somebody with somebody fluence until reaching predetermined, that is, completes
Regulation.
