Abstract
A water injection speed regulator is provided. The generally used separate injection well water distribution blanking plug water nozzle at present can not meet the injection distribution requirements of precise separate layer due to the fluctuation of the separate layer water injection after the distribution caused by the changes of the work system of the adjacent well and other factors. The water injection speed regulator includes: a speed regulating core 2, the outer end of the speed regulating core 2 is equipped with a speed regulating sleeve 4, one end of the speed regulating sleeve 4 is fixedly connected with a speed regulator cap 1, the other end of the speed regulating sleeve 4 is connected with a catch sleeve 7, the interior of the speed regulating sleeve 4 is provided with a speed regulating spring 3, a pin shaft 5 is arranged on the catch sleeve 7, a pin shaft spring 11 and a cam 6 are arranged on the pin shaft 5, a catch cap 8 is arranged on the inner cavity of the catch sleeve 7, a catch spring 10 and a catch shaft 9 are arranged on the inner cavity of the catch cap 8, a water nozzle 13 is arranged on the speed regulating sleeve 4, and a choke 12 is arranged on the speed regulating sleeve 4. The product is used for oilfield exploitation machinery.
Description
Technical field:
The utility model relates to the water filling governor that use in a kind of oil field.
Background technology:
The present separate water injection well water distribution plug water nozzle that generally uses, because of the change of offset well working system, offset well just in factors such as operation, changing of water injecting pump Hair Fixer, water injection rate of interval after the allotment still produces fluctuation, do not satisfy accurate multi-zone flow regulating requirement, and then influence oil well recovery ratio and moisture index.
Summary of the invention:
The technical problems to be solved in the utility model: provide a kind of accurate control hierarchy water injection rate, the oil field of stability of flow water filling governor.
The technical scheme that addresses the above problem:
The water filling governor, its composition comprises: the speed governing core, the speed governing cover is equipped with in the outer end of described speed governing core, end at described speed governing cover is fixedlyed connected with the governor cap, the other end links to each other with fishing sleeve, governor spring is equipped with in inside at described speed governing cover, on described fishing sleeve, bearing pin is housed, bearing pin spring and cam are housed on described bearing pin, on the inner chamber of described fishing sleeve, fishing bell is housed, on the inner chamber of described fishing bell, be equipped with and salvage spring and salvage axle, put in described speed governing water nozzle is housed, put in described speed governing and have restriction.
Above-mentioned water filling governor is fixedlyed connected by screw thread between described governor cap and the speed governing cover.
Above-mentioned water filling governor, the center internal diameter of described speed governing core are Φ 4-Φ 10.
Fixedly connected with screw thread between the above-mentioned water filling governor, described fishing bell and fishing sleeve.
Above-mentioned water filling governor, described bearing pin is fixed on the fishing sleeve.
Beneficial effect compared with prior art:
1. water filling governor of the present utility model, replace the separate water injection well water distribution plug after injection allocation is thrown in accordance with regulations, the flow of water filling governor of flowing through does not change with the variation of above factor, characteristic with regime flow, energy is the control hierarchy injected water volume accurately, improve field output, reach the development effectiveness of " steady oil control water ".
2. the speed governing core of this product can freedom move in the speed governing cover vertically, flow through when liquid and to produce sharp-tongued pressure reduction when the speed governing core flows out again, the restoring force of this pressure reduction and spring balances each other, and the weighing apparatus of spring restoring force guarantees that surely sharp-tongued pressure reduction weighing apparatus is fixed, and then guarantees liquid stream stability of flow.
3. this product can reach more stable constant current effect, and the flow and the water filling governor front and back pressure differential that promptly flow through the water filling governor after the plug structure fixed size are irrelevant, have accurately satisfied the seperated layer water injection requirement.
Description of drawings: accompanying drawing 1 is the assembling drawing of this product.
Accompanying drawing 2 is that the speed governing core center internal diameter of this product is the structural representation of Φ 4.
Accompanying drawing 3 is that the speed governing core center internal diameter of this product is the structural representation of Φ 10.
Concrete embodiment:
The water filling governor, its composition comprises: speed governing core 2, speed governing cover 4 is equipped with in the outer end of described speed governing core 2, end at described speed governing cover 4 is fixedlyed connected with governor cap 1, the other end links to each other with fishing sleeve 7, governor spring 3 is equipped with in inside at described speed governing cover 4, on described fishing sleeve 7, bearing pin 5 is housed, bearing pin spring 11 and cam 6 are housed on described bearing pin 5, fishing bell 8 is housed on the inner chamber of described fishing sleeve 7, on the inner chamber of described fishing bell 8, be equipped with and salvage spring 10 and salvage axle 9, on described speed governing cover 4, water nozzle 13 is housed, on described speed governing cover 4, have restriction 12.
Above-mentioned water filling governor is fixedlyed connected by screw thread between described governor cap 1 and the speed governing cover 4.
Above-mentioned water filling governor, the center internal diameter of described speed governing core 2 are Φ 4 or Φ 10.
Fixedly connected with screw thread between the above-mentioned water filling governor, described fishing bell 8 and fishing sleeve 7.
Above-mentioned water filling governor, described bearing pin 5 is fixed on the fishing sleeve 7.
