Shown in composition graphs 2 to Fig. 5 b, interior water nozzle 411 is provided with an interior water nozzle mouth 413, outside water nozzle 412 is provided with 2 outer water nozzle mouths 414.When water filling, rotate allotment bar 40, interior water nozzle mouth 413 is communicated with any one in two outer water nozzle mouths 414.Those skilled in the art can understand, interior water nozzle mouth 413 can be set to 2,5 or more, outer water nozzle mouth 414 also can be set to 2,5 or more, outer water nozzle mouth 414 and interior water nozzle mouth 413 also can be one-to-one relationship, those skilled in the art can select as required accordingly, as long as can when water filling, outer water nozzle 412 and interior water nozzle 411 communicate with each other.
Shown in composition graphs 1 to Fig. 4 c, outer water nozzle 412 is arranged in outer water nozzle sleeve 46, and such as outer water nozzle 412 is threaded connection and is fixed in outer water nozzle sleeve 461, also can pass through cementing agent (such as ceramic glue) and be fixed in outer water nozzle sleeve 46.In an example of the present utility model, outer water nozzle 412 is set on allotment bar main body 44 and hollow stem 45 by outer water nozzle sleeve 46, and be such as threaded connection, socket connection etc. is set in allotment bar main body 44.And be threaded connection between outer water nozzle sleeve 46 and lower contact 30, and be provided with O-ring seal in order to sealing at this connection of thread.
The annular chamber 462 that outer water nozzle sleeve 46 comprises outer water nozzle sleeve inner chamber 461 and is arranged on outer water nozzle sleeve 46.Annular chamber 462 is arranged on outside outer water nozzle sleeve inner chamber 461 along the circumferencial direction of outer water nozzle sleeve inner chamber 461, and annular chamber 462 be connected cavity 22 and be communicated with.
In an example of the present utility model, outside water nozzle sleeve 46 is provided with sleeve hole 463, the water nozzle mouth 414 of outer water nozzle 412 is communicated with annular chamber 462 by sleeve hole 463.Water nozzle mouth 414 and the sleeve hole 463 of outer water nozzle 412 are one-to-one relationship each other, namely water nozzle mouth 414 and the sleeve hole 463 of outer water nozzle 412 each other one_to_one corresponding be communicated with, certain those skilled in the art can understand, water nozzle mouth 414 and the sleeve hole 463 of outer water nozzle 412 are not one-to-one relationship each other, outer water nozzle 412 such as, arrange 2 water nozzle mouths 414, water nozzle sleeve 46 is arranged 1 sleeve hole 463 outside, when water filling, any one the water nozzle mouth 414 only taken in two water nozzle mouths 414 communicates with each other with sleeve hole 463.Certain those skilled in the art can understand, the water nozzle mouth 414 of outer water nozzle 412 can be set to 1,3 or more, sleeve hole 463 on outer water nozzle sleeve 46 also can be set to 1,4 or more, and those skilled in the art can select as required accordingly.
In another example of the present utility model, in each, the shape of water nozzle mouth 413 is the shape becoming 8-shaped to arrange be made up of with orthodrome small arc-shaped.The inflow when water filling accurately can be controlled by such design.When adjusting inflow, rotate allotment bar, by adjust orthodrome in the 8-shaped of interior water nozzle mouth 413 and small arc-shaped respectively with the adjustment coordinating to realize inflow of outer water nozzle mouth 414.Such as, when the part of the interior water nozzle mouth 413 making the small arc-shaped of interior water nozzle mouth 413 corresponding is communicated with outer water nozzle mouth 414, inflow is the little water yield; When whole interior water nozzle mouth 413 is all communicated with outer water nozzle mouth 414, inflow is maximum inflow.
The concrete structure of deployment device 100 is further illustrated below by the operating principle describing deployment device 100 in detail.
On the ground, first, regulate the adjustment screw thread of allotment bar 40 external surface, make the interior water nozzle mouth 413 of interior water nozzle 411 be in the below of the outer water nozzle mouth 414 of outer water nozzle 412, namely, water nozzle mouth 413 is in closed condition; Then, on the packer that deployment device 100 is connected to injection-production column jacket or oil pipe, and along with in the sleeve pipe entered under injection-production column jacket outside injection-production column jacket.
When seperated layer water injection, under enter measurement and adjustment instrument, measurement and adjustment instrument is made to adjust hole 43 to rotate allotment bar 40 by measurement and adjustment instrument, allotment bar main body 44 is up moved, and drive the hollow stem 45 be attached thereto up to move, thus water nozzle mouth 413 is communicated with outer water nozzle mouth 414 in realizing, the grooved through hole 42 now allocating bar 40 lower end is in air-tight state.Because outer water nozzle mouth 414 is communicated with annular chamber 462, make the water injecting allotment bar 40 inner chamber, flow in annular chamber 462 through hollow rod aperture 451, interior water nozzle mouth 413, outer water nozzle mouth 414 and sleeve hole 463 successively, along with the rising of annular chamber 462 middle water level, water in annular chamber 462 is flowed into be connected in cavity 22, flows out in connection cavity 22 finally by outlet 21.In the process of carrying out water filling, can by regulating the size of the aperture of interior water nozzle mouth 413 to regulate water injection rate.
When needs transfer drive, rotate allotment bar 40 and make allotment bar 40 continue up to move, when the grooved through hole 42 allocating bar 40 lower end fully passes over the upper end of outer water nozzle sleeve 46, deployment device 100 enters transfer drive state, and now, water nozzle mouth 413 is in closed state.Continue to rotate allotment bar 40, until through hole 42 with is connected cavity 22 and is communicated with, after injection of polymer, polymer, by through hole 42 inflow connection cavity 22, is flowed out from connecting cavity 22 by outlet 22 afterwards.
The beneficial effect of the technical scheme that the utility model provides is:
(1) deployment device that the utility model provides adopts water distribution bar lower end to be threaded with interior water nozzle hollow stem, makes water filling and transfer drive integration, facilitates water filling and transfer drive to switch back and forth, and then facilitate the oil exploitation work of current oil-field flooding and transfer drive;
