In petroleum production engineering the injecting process, conventional injection well downhole flow regulator is mainly divided into retrievable type injection well downhole flow regulator, survey limit, limit water flow regulator, ground water pressure generation wireless regulation and control injection well downhole flow regulator etc. at present.Although these several injection well downhole flow regulator costs are low, pulling and running tool is simpler, but there is larger defect at aspects such as layering water allocation efficiency, layering water distribution precision, long-term water distribution monitoring and direct-reading two-way communications, particularly current most downhole water flow regulator does not possess independently flow meter, cannot to flow, survey tune in real time for a long time, thereby determine accumulative total injection flow.
Choke valve on retrievable type injection well downhole flow regulator easily stings damage, does not have throttling action, does not reach the object of seperated layer water injection.Meanwhile, once distributing tap is selected, water injection rate just cannot need to regulate in time according to stratum water filling, and both off-energy, more easily damaged choke valve.
ZL201220056520.0 discloses a kind of automatic survey and has adjusted and monitoring dispensing injection well downhole flow regulator, comprise water injection pipe, flow meter pipe nipple, underground water-injection layer position status data collecting unit, control circuit, motor and water nozzle, this injection well downhole flow regulator can realize the real-time automatic governing of each layer of down-hole bit traffic, down-hole pressure, temperature and flow parameter Real-Time Monitoring and storage, the transmission of non-contact data and instruction and down-hole are automatically tested the automatic survey tune of the functions such as envelope and monitor dispensing injection well downhole flow regulator.But for the larger oil well of upper and lower pressure reduction, the switch of the water nozzle of this injection well downhole flow regulator can not arrive precalculated position under differential pressure action, thereby cause the signal of telecommunication and the actual water injection rate of transmission to have deviation.
Utility model content
The purpose of this utility model is to cause the problems such as quantitative injection is accurate not in order to solve pressure differences that existing injection well downhole flow regulator exists, and then a kind of automatic adjustable injection well downhole flow regulator is provided.
The purpose of this utility model is achieved in that
The utility model is by top connection, main body, lower contact forms, top connection, main body and lower contact are threaded successively, wherein main body is by plug, battery, control circuit, motor, driving shaft, adjustable water nozzle, baffle ring, turbine flowmeter and holding wire form, main body has two axial lines parallel axial counterbore and axially extending bore, the top of main body has connection shaft to the radial communication hole of counterbore and axially extending bore, bottom has connection shaft to counterbore, the fluid hole of axially extending bore and main body outer wall, battery, control circuit, motor, driving shaft is connected successively with adjustable water nozzle and is arranged in the axial counterbore of main body, adjustable water nozzle middle part has the radial hole corresponding with the fluid hole of main body, plug is arranged on the axial counterbore upper end of main body by screw thread, turbine flowmeter is arranged on the shoulder of axially extending bore internal upper part of main body, baffle ring is fixed on turbine flowmeter in the axially extending bore of main body, holding wire connects battery and turbine flowmeter by intercommunicating pore.
The beneficial effects of the utility model are: the utility model can be used for flushing, not affected by differential pressure, and long service life is accurately allocated water injection rate, and energy loss is little, can keep for a long time accurate layered quantitative water filling, and reaching waterflooding extraction should produce effect; When layered waterflooding quantity is manually adjusted, do not need to sit layer, reduced to survey and adjusted workload, easily realize; Only need a tubing string construction, just can complete meticulous dispensing and control, without later stage manual intervention and measurement, save a large amount of manpower and materials; Do not need pulling water nozzle, shorten the allotment time, reduce labour intensity, at high angle hole and horizontal well, can be widely used yet; Need to not use cable in down-hole, reduce the various downhole water flow regulator problems that cause because of cable fault.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the utility model is by top connection 1, main body 4, lower contact 12 forms, top connection 1, main body 4 and lower contact 12 are threaded successively, and wherein main body 4 is by plug 2, battery 5, control circuit 6, motor 7, driving shaft 8, adjustable water nozzle 9, baffle ring 13, turbine flowmeter 14 and holding wire 15 form, and main body 4 has two axial lines parallel axial counterbore 18a and axially extending bore 18b, and the top of main body 4 has connection shaft to the radial communication hole 17 of counterbore 18a and axially extending bore 18b, and bottom has connection shaft to counterbore 18a, the fluid hole 10 of axially extending bore 18b and main body 4 outer walls, battery 5, control circuit 6, motor 7, driving shaft 8 is connected successively with adjustable water nozzle 9 and is arranged in the axial counterbore 18a of main body 4, adjustable water nozzle 9 middle parts have the radial hole corresponding with the fluid hole 10 of main body 4 11, plug 2 is arranged on the axial counterbore 18a upper end of main body 4 by screw thread, turbine flowmeter 14 is arranged on the shoulder of axially extending bore 18b internal upper part of main body 4, baffle ring 13 is fixed on turbine flowmeter 14 in the axially extending bore 18b of main body 4, and holding wire 15 connects battery 5 and turbine flowmeter 14 by intercommunicating pore 17.
