Abstract
The invention relates to an underground electric adjustable water injection nozzle of an oil field water injection well, and belongs to the field of oil field water drive oil extraction. The problem that an existing water injection nozzle of an oil field water injection well cannot be adjusted can be solved. The underground electric adjustable water injection nozzle is characterized by being composed of a power supply and instruction receiving port, a micro-power consumption single-chip microcomputer, a drive circuit, a micro-driving motor, a sealing baffle, an electric shaft, an execution block, a water inlet and an oil nozzle. According to the underground electric adjustable water injection nozzle, the opening of the water inlet can be controlled according to control commands received by the power supply and instruction receiving port, and then the underground water injection nozzle of the oil field water injection well can be electrically adjusted.
Description
Technical field
The present invention relates to the adjustable water-filling nozzle of a kind of water injection well in oil fields downhole electric in oilfield water flooding oil recovery field.
Background technology
Along with oil field development enters the middle and later periods, stratum energy declines, and oily well yield also declines thereupon, and now, water flooding becomes the major measure that improves recovery ratio.At present, state-of-the-art a kind of water flooding regime is exactly seperated layer water injection, by the effective control to underground different layers position injected water volume, suitably supplements stratum energy, thereby improves the crude oil recovery percent of reserves of corresponding oil well, reaches the object that improves oil recovery.In practice, along with the dynamic change of strata pressure, often need to change the size of water injection well water nozzle and adjust water injection rate, this just need to salvage out by former water nozzle, then the water nozzle that meets water filling condition is put into down-hole.If do not meet injection allocation requirement through measuring after water nozzle drops into, just need to again pull water nozzle out, then drop into new water nozzle, until meeting injection allocation, the water nozzle dropping into requires.
Summary of the invention
The object of the present invention is to provide the adjustable water-filling nozzle of a kind of water injection well in oil fields downhole electric, solve the water-filling nozzle of different opening can only be changed by salvaging water-filling nozzle in an existing oil field again difficult problem to ground, the enforcement of the method can realize and realize electronic adjustable to water injection well in oil fields underground water-injection mouth.
The technical scheme adopting is:
Adjustable water-filling nozzle is by powering and command reception port, ultra low-power microcontroller, drive circuit, micro-driving motor, sealing plate, electric drive axle, execution block, water inlet, atomizer form.The control command that this invention can receive by power supply and command reception port, controls the aperture size of water inlet, and then realizes electronic adjustable to water injection well in oil fields underground water-injection mouth.
The beneficial effect of the method is:
Solve the water-filling nozzle of different opening can only be changed by salvaging water-filling nozzle in an existing oil field again difficult problem to ground, the enforcement of the method can realize and realize electronic adjustable to water injection well in oil fields underground water-injection mouth, avoid the waste of a large amount of manpower and materials, meet the demand of field produces.
Brief description of the drawings:
Accompanying drawing 1 is the adjustable water-filling nozzle composition of water injection well in oil fields downhole electric structural representation;
In figure, 1 is power supply and command reception port; 2 is ultra low-power microcontroller; 3 is drive circuit; 4 is micro-driving motor; 5 is sealing plate; 6 is electric drive axle; 7 is execution block; 8 is water inlet; 9 is atomizer.
Detailed description of the invention:
Below in conjunction with brief description of the drawings present embodiment.It is made up of following methods: this electronic adjustable water-filling nozzle is arranged on each the water filling layer in water injection well in oil fields down-hole, by this adjustable water-filling nozzle by powering and command reception port (1), ultra low-power microcontroller (2), drive circuit (3), micro-driving motor (4), sealing plate (5), electric drive axle (6), execution block (7), water inlet (8), atomizer (9) form.When ultra low-power microcontroller (2) is powered by adjustable water-filling nozzle and command reception port (1) receives after outside fill order, give an order, directly drive micro-driving motor (4) running by drive circuit (3), determine the time of implementation of micro-driving motor (4) according to the content of instruction, micro-driving motor (4) can driving electric axle (6) in the time of forward and reverse running and execution block (7) move back and forth forward or backwards, execution block (7) can enclosure portion in motion process or whole water inlets (8), thereby reach the object of control atomizer (9) flow, this invention is also provided with sealing plate (5) and ensures that adjustable water-filling nozzle is by powering and command reception port (1), ultra low-power microcontroller (2), drive circuit (3), micro-driving motor (4) are avoided the invasion and attack of injected water in addition.The control command that this invention receives by power supply and command reception port, controls the aperture size of water inlet, and then water injection well in oil fields underground water-injection mouth has been realized to electronic adjustable function.
