Definitions
- the invention relates mainly to the field of water supply and, in particular, can be used for cleaning water wells.
- a drop in water production in water wells is usually caused by clogging of the wells.
- drilling of new wells is a long, expensive and often associated with environmental and legal problems process, there is a need to clean water wells.
- a device for cleaning pipes (patent USN ° 6474349), containing a mechanical device for generating acoustic waves, an electric source of high frequency and a source for polarizing the current, the electric current generated by the source is used to excite or activate a mechanical device for generating acoustic waves.
- a known method of oil production using energy of elastic vibrations (patent RUN ° 2392422), which can be used to clean water wells, is selected as a prototype, including placement in the well at the working depth of the borehole apparatus, which is connected to a ground source of power frequency and contains an ultrasonic transducer that provides the creation of elastic vibrations of high frequency, the excitation of elastic vibrations of different frequencies and, subsequently, mainly repeatedly the impact of elastic vibrations of different frequencies on the oil reservoir, characterized in that the impact of elastic vibrations on the oil reservoir is carried out by high and low frequency vibrations, and two independent vibration sources are used to create high and low frequency elastic vibrations, one of which is made in the form at least one emitting ultrasonic, mainly magnetostrictive the converter, and the second is based on an electric pulse device that provides the creation of low-frequency elastic vibrations, is connected to a ground source of industrial frequency power and includes an electrically interconnected charger, a storage capacitor block, a discharge block equipped with electrodes, and two switching means , one of
- the known method and device have a low efficiency of cleaning water wells, are difficult to manufacture and operate.
- the problem to which the invention is directed, is to increase the efficiency of cleaning water wells.
- the device comprises a downhole tool, consisting of an electro-hydraulic unit with an oscillatory circuit sequentially located in the same housing, changing the parameters of which can be used to control the pulse duration, packing frequency and signal spectrum of the electro-hydraulic unit to change the exposure zone, and ultrasonic units with electro-acoustic transducers, pressure and flow sensors, hydrophone, pump, ultrasonic and pulse generators, monitoring equipment for sensors, a control unit for a downhole tool, equipped with a synchronizer for the operation of electro-hydraulic and ultrasonic blocks, while a discharge chamber and a protective cover are located in the lower part of the downhole tool body.
- FIG. 1 and FIG. 2 shows a diagram of the proposed device.
- the device consists of a borehole and surface parts.
- the downhole part includes a downhole tool connected to the ground part of the equipment by a geophysical cable 1.
- an electro-hydraulic unit 7 and an ultrasonic unit 4 with electro-acoustic (magnetostrictive) transducers 3 are installed in series with the cable lug 2 above, and between the ultrasonic unit 4 and the electro-hydraulic unit 7 are a pressure compensator 5 and a connecting unit 6.
- a pressure compensator 5 and a connecting unit 6 6
- stream 1 1 hydrophone 12 and the pump is not shown.
- the downhole tool has a discharge chamber 8 and a protective cover 9.
- Electro-acoustic transducers 3 mounted in the ultrasonic unit 4 can be installed in parallel, parallel-perpendicular, sequentially (see Fig. 3) - in order to create the most effective radiation pattern corresponding to the conditions of mudding of the well being cleaned.
- the ultrasonic unit 4 is equipped with a device for compensating the pressure 5 (equalizing the pressure inside and outside the unit), in order to prevent cavitation inside the unit.
- Cable 1 is introduced into the electro-hydraulic unit 7 through an ultrasonic unit 4.
- This embodiment of the device is optimal for creating short discharges inside the well in order to form an effective shock wave.
- the combined ultrasonic and electro-hydraulic effects can improve the efficiency of well cleaning, since in this case the impact has a wider operating area.
- the ground part of the device includes: an ultrasonic generator 13 connected via cable 1 to the ultrasonic unit 4 of the downhole tool; a pulse generator 14 connected by a cable 1 to an electro-hydraulic unit 7 of a downhole tool; monitoring equipment for sensors 15 and a single control unit 16 of the downhole tool with a device for controlling the pulse duration, frequency of stuffing and the signal spectrum of the oscillating circuit of the electro-hydraulic unit and a synchronizer (not shown conventionally) of the operation of the ultrasonic generator 13 and electro-hydraulic unit 7.
- the device (see Fig. 1) works as follows.
- the downhole tool is lowered into the well (see Fig. 2).
- the control block of sensors 15 determine the degree (parameters) of contamination of the well.
- the control unit 16 uses the control unit 16, the signal of the corresponding frequency from the ultrasonic generator 13, through the geophysical cable 1, is fed to the electro-acoustic transducers 3 of the ultrasonic unit 4.
- the ultrasonic unit 4 is connected to an ultrasonic ground-based generator 13 with the following optimal parameters obtained experimentally:
- the frequency range is 17-24 kHz
- the generator can operate with manual and computer control.
- the signal from the pulse generator 14, through the geophysical cable 1, is supplied to the electro-hydraulic unit 7.
- the signal has the following optimal parameters obtained experimentally:
- the output amplitude of the pulse is 120-240 V
- the amplitude of the current pulse is not more than 2.5 A
- the generator can operate with manual and computer control.
- the impact of the low-frequency signal, carried out by the ultrasonic unit 4, and the high-frequency signal, carried out by the electro-hydraulic unit 7, is carried out jointly (synchronously), which leads to a change in the relative position of the particles in the gravel filling of the wells, resulting in the removal of colmatant.
- changes in the configuration of gravel particles leads to a change in the interference pattern of ultrasonic waves, and, consequently, to a shift in the maximums of ultrasonic exposure. Due to this, a more complete cleaning is achieved.
- the exposure zone of the electro-hydraulic unit 7 is varied using the parameters of the oscillatory circuit in this unit (inductance, capacitance and resistance). Due to this, the pulse duration and the packing frequency are changed, and, consequently, the signal spectrum, which leads to a change in the exposure zone. Due to this, an impact is exerted on various zones of clogging (mainly near the filter pipe and on the border of gravel filling).
- the location of the electro-hydraulic unit 7 in the lower part of the downhole tool allows you to provide a double front of the shock wave: reflected from the bottom of the well and emanating from the electro-hydraulic unit 7.
- the front is a kind of sphere.
- the proposed device with the smallest possible dimensions allows you to effectively clean the water wells.
