Specific implementation mode
Detailed description in relation to the utility model and technology contents, cooperation description of the drawings is as follows, however attached drawing is only to refer to
With purposes of discussion, not it is used for limiting the utility model.
According to Fig. 1, a kind of layered profile control seperated layer water injection integrated pipe column, including the layered profile control being connected on oil pipe are layered
Water filling integrated tool 3, layer separating packer 2, hydraulic anchor 1, bottom sieve stifled 4, the layered profile control seperated layer water injection integrated tool is extremely
Two are arranged less, corresponds to different water filling layers respectively, the layer separating packer is also at least arranged two, is located at different injection
The layer separating packer upper end of between the layer and top of top layer's water filling layer, top layer connects hydraulic anchor, and the lowermost end of oil pipe is set
Bottom set screen blinding.
According to fig. 2, the layered profile control seperated layer water injection integrated tool, including anti-rotation positioning sleeve 301, upper joint sleeve 302,
Big compression spring 303, fixed fuse 304, rotation fuse 305, lower joint sleeve 306, the upper joint sleeve lower end and fixed fuse upper end
Screw thread type connects, and the big compression spring 303 is sleeved on fixed outside core, and big compression spring upper end withstands on upper joint sleeve lower face, the rotation
Core 305 is inserted by lower joint sleeve upper port in lower joint sleeve, and rotation fuse top surface is connected to fixed fuse lower face, described
Fixed 304 lower face of fuse and 305 upper surface of rotation fuse offer water filling water-distributing gap, and water filling water-distributing gap is to open up with one heart,
The lower joint sleeve 306 opens up radial profile control outlet, and 303 lower end of big compression spring is withstood on pressure ring, and pressure ring lower end is pressed in pressure
On cap, pressure cap is by screwed connection in the upper end of lower joint sleeve.5 bottom end of rotation fuse connects small pressure spring 7, small pressure spring lower end
It withstands in the chuck that lower joint sleeve inner wall opens up.The upper joint sleeve inner wall installs anti-rotation positioning sleeve 1.The lower joint sleeve inner wall
Installation is used for the rotary sleeve 308 of plugging and profile con-trol outlet, and the lower joint sleeve lower end connects lower contact 309, the limit of rotary sleeve lower end
In lower contact upper surface.
Rotation fuse upper end outer wall opens up upper edge, the interior chuck of pressure cap upper end inner wall setting, the upper edge
Limit is in lower joint sleeve upper surface and pressure cap between chuck.
The rotation fuse opens up radial drive connection hole, is drivingly connected hole and is used for connecting the driving machine for surveying tune tool
Structure.
The tubing string can meet simultaneously mainly using layered profile control seperated layer water injection integrated tool as profile control water injection tool
Profile control and water-filling function demand, and realize fixed tubular column switching profile control, water-filling function.Using hydraulic anchor as tubing string anchor tool
The string creep phenomenon caused by pressure oscillation can be eliminated.Simultaneously using the closed packer with self-locking function as layering
Tool, packer still keeps setting state when profile control is constructed.Backwash valve is combined with precise screen pipe, can be to entering when anti-flushing well
Height in oil pipe glues profile control agent and generates compared with Strong shear effect, avoids generating blocking to backwash valve.
After layered profile control seperated layer water injection integrated pipe column is according to the tubing string tripping in place of design, just suppressed by oil pipe
At layering packer setting, packing element is not withdrawn when oil pipe pressure release.Need to keep all layers of waterflood path and non-when profile control
Target zone profile control channel is closed, and is opened target zone profile control channel and is carried out profile control construction.When normal water filling, it is logical to close all profile controls
Waterflood path is opened, and carries out water injection rate allotment in road.Closed packer can be unsealed in anti-flushing well, disclosure satisfy that huge discharge
The demand of well-flushing.Meanwhile backwash valve connection precise screen pipe can realize compared with Strong shear the viscous profile control agent of height, it is high when preventing anti-flushing well
Viscous profile control agent blocks backwash valve.
Tool is gone into the well according to design tubing string, it is generally the case that by the rotation fuse of water distribution mechanism by water when tool is gone into the well
Mouth is adjusted to closed state, while the rotary sleeve of profile control mechanism is adjusted to closed state.In process of production, sharp as needed
Tool is adjusted with mating switch, and switch-mode regulation is carried out to layered profile control, water filling integrated tool in underground.In water filling, keep adjusting
Port closing is cutd open, tripping in surveys tune tool and adjusts rotation fuse 305, by rotating the cooperation of fuse 305 and fixed fuse 304, changes
Become throttling of the size control in water nozzle section on fixed fuse 304 to injection water, realizes switch and the water injection rate allotment of water filling port.
When needing to carry out profile control operation, filling outlet is kept to close, tune tool adjusting rotary sleeve 308 is surveyed in tripping in makes it move up, and opens
Profile control exports, and the outlet of large scale profile control will not be to the generation throttling of the profile control agent of injection, to ensure to inject after optimization design
The sealing characteristics of profile control agent.It needs to close profile control outlet after the injection for completing profile control agent and replacement slug, prevents stratum from returning and spit.
The above is only the preferred embodiment of the present invention, non-to limit the scope of the claims of the utility model,
He uses the equivalence changes of the utility model patent spirit, should all belong to the scope of the claims of the utility model.
