Description
Technical field
The utility model is related to the underground water-injection equipment in oil field, especially ground to control time-sharing layered water filling cable control water distribution dress
It puts.
Background technology
With deepening continuously for the fine waterflooding extraction in oil field, in water injection well the injecting process, there are same water injection well have it is high,
The larger difference of low-permeability layer water suction, causes interlayer water injection rate difference big.Particularly some oil wells have been enter into ultra-high water-containing and open at present
Late period is sent out, each oil reservoir interlayer contradiction of oil well is more prominent, and injection water is preferentially advanced by leaps and bounds along high permeability zone passage, so as to influence to inject water
Involve oil-bearing layer volume, reservoir water flooding is serious, and comprehensive water cut increases, and increases the Tapping Residual Oil of less permeable layer in oil well
Difficulty, oilfield exploitation difficulty constantly increase, and conventional zonal injection technology is taken not adapt to the needs of water flooding.It is another
Aspect, at present oil field conventional injection well downhole flow regulator mostly using regular tripping in wireline test allocate, such as test allotment workload it is too late
When, for conventional injection well downhole flow regulator water nozzle during high permeability formation injection rate is controlled, water nozzle aperture is easily big by thorn, surpasses high permeability formation
Note, low-permeability layer is shorted while wellbore pressure is caused to reduce.
In addition, subdivision injection technique is controlled each layer water using conventional injection well downhole flow regulator water nozzle, is tested using tripping in wire Launching and Bailing
Technique is surveyed and work is adjusted also to be subject to hole deviation and scale effect, when hole deviation is more than 50 ° or serious pit shaft fouling, instrument tripping in
Difficulty, which can not be completed to survey, to be adjusted or even pulling can be caused to be hampered or meet card, is caused underground work or is done over again, the labor intensity of worker
Greatly.The above problem has become the restraining factors for improving water flooding effect.
The Chinese invention patent specification for the Application No. 201010285066.1 that on December 04th, 2013 authorizes discloses
A kind of automatic cycle derailing switch and seperated layer water injection system and automatic cycle water-filling method, the seperated layer water injection system is in underground water-injection

Keying sequential is set with respectively, and each automatic cycling switch device is opened and closed by the sequential automatic alternate of setting, to each oil reservoir
Cycling water filling is carried out, realizes underground oil reservoir recurrent pulses water filling.This flood pattern and its water-filling method on ground once set
After the fixed specific time cycle, water injection cycle cannot be changed in the injecting process, can not be met in production process because note adopts adjustment
It needs and adjusts the requirement of water injection cycle.Simultaneously because being limited be subject to the powering quantity of underground automatic cycle derailing switch, switch follows
Ring number is limited, it is impossible to adapt to long-term, more rounds, time-sharing layered water filling, can not meet the needs of long-acting waterflooding extraction in oil field, mesh
The waterflooding extraction technology of preceding oil reservoir still needs to improve.
The content of the invention
The utility model is in view of the deficiencies of the prior art and shortcoming, to provide ground and control time-sharing layered water filling cable control water distribution
Device only needs tripping in one to plow downhole water injection string, can be on ground according to the needs of reservoir waterflooding, and setting loop cycle is divided
Layered water filling overcomes each oil reservoir interlayer contradiction distinct issues of oil well.Exempt using measurement and adjustment instrument device allocate water injection rate, solve by
It is surveyed caused by this and adjusts the problems such as workload rapid growth is with equipment and undermanned contradiction, improve the effect of waterflooding extraction.
To reach above-mentioned purpose, the utility model employs following technical solution：Ground controls time-sharing layered water filling cable control
Water dispensing apparatus includes microprocessor and motor, is connected by top connection, clamping cap, outer tube and lower contact and note is equipped in the tube body formed
Aquaporin and biasing control passage, water inlet are arranged in the next door between waterflood path and biasing control passage, and water outlet is set
It puts in the biasing control passage lower end of lower contact；Microprocessor is with motor by controlling cable series connection, leading to mounted on biasing control
In road, by the way that cable is controlled to be connected with ground control box.
Compared with prior art, the utility model has following significant effect：The utility model is on the ground of water injection well
Volume control device is installed to be connected with ground control box in surface current journey, is separated water filling layer with layer separating packer, by cable control water distribution
Device corresponds to water filling layer in the downhole water injection string, in downhole water injection string with the corresponding cable control water distribution of each water filling layer
Device is by controlling cable to be connected with ground control box；Ground control box controls the injection water of each water filling layer on ground in real time
Amount and injection length, the cable control water dispensing apparatus of each water filling layer in underground according to the program of ground control box setting and instruction,
