Description

The invention relates to the oil and gas industry and can be used both to intensify the production of oil, natural gas and gas condensate with an increase in well production, and for resuscitation of idle and low-production oil wells, low-pressure gas or gas condensate wells with an increase in the oil recovery factor (ORF) while decreasing the water content of the pumped oil or gas-liquid mixture, as well as gas and gas condensate by electromagnetic resonance displacement of hydrocarbons from productive formation.

Currently, there are many ways to intensify and secondary oil production, which remains in the oil reservoirs. These methods are usually associated with the high energy expenditure necessary to create forces displacing oil from the formation, and to reduce the forces that retain the oil remaining in the oil-bearing formation. The most characteristic of the methods are presented as analogues of the proposed method, which allows a systematic approach to the selection of the prototype and to the presentation of the distinguishing essential features of the invention.

A known method of secondary oil production by initiating redox reactions in it (see patent RU No. 2303692, C2; published July 27, 2007) using electric current developed by American specialists from the company Electro-Petroleum, Inc. The essence of the invention lies in the fact that for the compulsory production of oil from an underground reservoir with the first and second oil-bearing areas, a first well is constructed in the first area of the formation and a second well in the second area of the formation. Electrodes are lowered into each of the wells, between which a periodic voltage difference is created by applying a DC bias voltage to them and an alternating AC component with an amplitude applied to it, which initiates redox reactions in the oil to decompose the long-chain hydrocarbons and polycyclic compounds contained in it into compounds low molecular weight and hydrogenated oil. When an electric current flows through the formation in the capillary and relict water in it, electrolysis begins, as a result of which activators are released in the groundwater that accelerate the oxidation and reduction reactions in the oil. In this case, cathodic reduction occurs on negatively charged interface surfaces of compounds contained in oil, and anodic oxidation occurs on positively charged interface surfaces. Redox reactions can be initiated in both aliphatic and aromatic oils. When oil viscosity decreases as a result of redox reactions, its mobility or fluidity increases, and oil flows from the reservoir into the production well. In addition, as a result of the mineralization of oil, which occurs when electric current is passed through the oil reservoir, carbon dioxide is formed, which, dissolving in the oil, also reduces its viscosity and increases oil production. And finally, in addition to increasing the fluidity of the oil, the known method accelerates the electrochemical reactions taking place in the oil, as a result of which the quality of the produced oil increases: when electric energy is supplied to the oil-bearing formation, hydrogen and other gases are released from the formation. So, for example, hydrogen, which at a sufficiently high hydrostatic pressure interacts with oil and partially hydrogenates it, increases the grade and quality of the produced oil, and the oxidative reactions occurring in the oil are accompanied by its oxidation, which also improves the qualitative characteristics of the oil.

However, this method has a significant drawback, which is that despite the creation of a direct electric current electroosmotic effect (dissolved electrolytes and charged particles suspended in oil along with oil molecules migrate towards the cathode), the superimposed component of the alternating current has an amplitude only to ensure of redox reactions and decomposition of long-chain hydrocarbons and polycyclic compounds contained therein into low molecular weight compounds mass. That is, the oil phase of the reservoir fluid receives some additional mobility, but does not enter the resonance at the molecular level, which stepwise increases the energy of hydrocarbons. In addition, this method includes the use of direct current at high voltages and high currents. At the same time, as you know, DC systems consume a large amount of electric energy, and with significant losses in the oil and gas reservoir, this significantly increases the cost of oil production.

Also known is a method of developing an oil reservoir (see patent RU No. 2241118, C1; published November 27, 2004), which includes injecting a working agent through injection wells, taking oil through production wells, and supplying electric current to the reservoir through a pair of wells. Through one well, an alternating or pulsed electric current is supplied to the reservoir by means of electrodes, which are made in the form of a drill for a perforator with the exception of electrical circuit with the casing and lead out of the casing of the well into the formation through additionally formed perforations. In another well, the zero phase of the current source is connected to the casing. As a result of electrical exposure to the oil-bearing formation, the formation is heated to a predetermined temperature, and the phase permeability of the oil-water fluid changes in a radius exceeding the radius of the thermal effect by several orders of magnitude.

However, this method also has a significant drawback, which is that despite the formation being heated, even if there is no direct current, but only with alternating current with a voltage of 220 V, the current frequency is also not resonant and fully corresponds to the industrial frequency of 50 Hz. This fact significantly limits the possibility of additional oil production.

Also known is a method of developing oil and gas condensate fields (see patent RU No. 2208141, C1; published July 10, 2003), designed to increase the degree of extraction of oil or other vaporized liquids from oil sources on land or at sea by applying high frequency electric pulses to the oil reservoir . According to this method, an electromagnetic wave emitter is placed in a well and, together with it or separately, an electrode of a high frequency electric field. They act on the oil reservoir in the initial period with electromagnetic waves of ultrahigh frequency, then with a frequency of 15-30 kHz and finally with a frequency of 0.01-15 Hz until the reservoir is partially heated. After that, the oil reservoir is exposed to a high-frequency electric field, which is phased with electromagnetic and natural electric fields, thereby ensuring the mutual induction of electromagnetic and electric fields, their resonance and the change in the physicomechanical properties of the oil reservoir. The resulting evaporation of water creates additional vapor pressure on the formation.

This known method, although it already uses the resonance effect, based on the mutual induction of the natural electric field of the formation and induced simultaneously by electromagnetic and electric fields for additional heating of the formation, however, it also significantly limits the possibility of additional oil production, because does not directly introduce hydrocarbon molecules (dipoles) into the resonance, i.e. Don't resonate with them directly.

In addition, there is a method for increasing the degree of extraction of oil or other vaporized liquids from oil reservoirs in land or at sea (see patent SU No. 1838594, A3; published August 30, 1993), developed by Norwegian specialists from Industrialcontact Ing O. Ellingsen End Co. . ". The essence of the invention lies in the fact that in the oil reservoir create a vibration with a frequency closest to the natural frequency of the reservoir to weaken the bonding forces between the reservoir and the oil. Previously, the well is filled with a metal fluid, including mercury, and the electrodes are placed in two neighboring wells. Vibration of the skeleton of the formation is carried out with its simultaneous electrical stimulation by applying alternating voltage. High-frequency vibrators can be supplied from a generator and a frequency converter both single-phase currents and three-phase currents to three neighboring wells. Resonant vibrations push oil out of the field, generating additional heat due to friction between the oil and the skeleton of the reservoir.

A significant disadvantage of this method is the use of toxic mercury. In addition, in this case, a collector skeleton is introduced into resonance, which, despite the separation of oil and reservoir phases, should inevitably lead to spasmodic clogging (clogging of the filtration channels with mechanical particles), obliteration (clogging of the pore channels with a destroyed cementitious substance located between the rock grains ), as well as clogging with clots of deposits of asphalt-resin-paraffin components of oil, salts, etc. (see Mishchenko I.T. Well production: A textbook for universities. - 2nd ed., rev. - M.: Oil and Gas Publishing House of the Gubkin Russian State University of Oil and Gas, 2007).

And finally, a known method of developing an oil and gas condensate field and equipment for its implementation (see patent RU No. 2049914, C1; published 10.12.1995), including the use of emitters and exposure to the oil reservoir by electromagnetic waves. Preliminarily determine the contour of the field (the boundary of the oil-water contact), drill rows of injection and production wells, pump water into injection wells, act on the water-oil-saturated part of the formation by ground wave energy sources, and additionally act on the circuit with electromagnetic waves having amplitudes of different magnitudes and directions in the corresponding half-periods creating a driving force directed towards the producing wells. Moreover, when extracting oil from production wells, they simultaneously automatically monitor the movement of the circuit, maintaining its similarity to the original shape. After oil production from the field, oil is extracted from rock lenses with reduced porosity and permeability coefficients, the location of which is known in the reservoir, by irradiation of part of the lateral surface of the lenses with electromagnetic waves so that the direction of oil displacement from them through another non-irradiated part of the lateral surface coincides with the direction to the producing well.

The disadvantage of this method also lies in the fact that the full potential of the resonance-wave action on the hydrocarbon fluid is not used. In this case, we are talking about the simultaneous electromagnetic resonance action at several points along the contour of the proposed oil and gas bearing formation in order to create vibrational excitation of the formation fluid in individual zones of the oil-bearing reservoir with elements of the local vibro conveyor effect. As a result, impulse impulse is imparted in a certain direction to oil accumulations (layer-by-layer planing) that are trapped and captured, however, the energetically excited accumulations of oil from the reservoir are not forced to move along a closed loop from the injection (or neighboring) well directly to the producing well in a controlled mode going on.

The closest analogue is a method of intensifying oil production and resuscitation of idle oil wells by means of electromagnetic resonance effects on the reservoir (see patent RU No. 2379489, C1; published January 20, 2010), which includes generating counter electromagnetic fluxes from two or more neighboring wells as a day surface, and opposite the reservoir in the perforation zone with frequencies that resonate with the natural frequencies of the reservoir hydrocarbons. In this case, the initial point of peak resonance occurrence during the oncoming radiation is localized near the injection (or neighboring) well, tracking the peak resonance by the principle of real-time feedback by the receiver-generator on the day surface. Then, in a controlled mode, counter-radiation of modulated electromagnetic waves is continued when the frequency of natural vibrations of the formation hydrocarbons is superimposed on the carrier frequency so that the radiation power from the producing well significantly exceeds the power of the oncoming radiation from the injection (or neighboring) well. Then, due to the controlled adjustment of the generator capacities, the peak resonance together with the perturbed fluid begin to shift toward the producing well with repeated runs, thereby providing additional forced displacement of reservoir hydrocarbons.

The disadvantage of this method is that the damping process of counter-directed electromagnetic waves requires significant pulsed energy consumption, although in a periodic mode of implementing peak resonance runs from the injection (or neighboring) to the producing well.

The objective of the invention is the creation of a method devoid of the disadvantages of the prototype method and realizing the “relay effect” of counter-directed flows of modulated electromagnetic waves with minimizing the attenuation of electromagnetic waves of resonant frequency along the entire length of the reservoir between the producing well and at least one well adjacent to it , including discharge.

The present invention is directed to increasing the efficiency of resonant excitation of formation fluid hydrocarbons in individual portions of the oil reservoir by imparting a straining impulse in a certain direction and to subsequent controlled directional displacement of formation hydrocarbons by repeated runs of peak resonance with frequencies equal to the natural frequencies of the molecules (dipoles), in a closed system from an injection well (or the nearest neighboring one, or a group of nearest neighboring wells) through the flue reservoir directly to a specific production well, most carefully pushing through precisely the locations of hydrocarbon fractions blocked by formation water in traps and captures, by passing alternating electric current through mineralized formation water also with a frequency resonating with the natural frequency of formation hydrocarbon vibrations, thereby retransmitting counter-directed modulated electromagnetic fluxes over the entire length of the reservoir between adjacent wells, yvaemymi proposed method.

The technical result achieved by using the proposed invention is:

- an additional increase in the production rate of the producing well;

- a significant increase in the oil recovery coefficient (CIN) up to 50-60 percent, including due to the release of hydrocarbons from traps and captives;

- reanimation of oil and gas condensate wells, which have been idle for many years due to previously used inefficient production technologies, as well as reanimation of low-pressure gas wells;

- an increase in the energy and mobility of oil, which contributes to its displacement into the producing well, increasing the rheological properties of the reservoir fluid;

- an increase in oil temperature and, as a consequence, a decrease in its viscosity, which is especially important when developing highly viscous hydrocarbons;

- reduction of water cut in the well fluid due to priority displacement of hydrocarbon fractions from the reservoir;

- obtaining data on the geological and geophysical parameters of the developed section of the reservoir.

The specified technical result is achieved by the fact that in the method of producing oil, natural gas and gas condensate by electromagnetic resonant displacement of them from the reservoir, including the creation in the reservoir between the producing well and the adjacent well, including the injection, with resonance wave generators and emitters immersed in the said wells to the depth of the perforation zone, counter-directed modulated flows of electromagnetic waves resonating with the proper the oscillation frequency of the hydrocarbon fluid, the formation using the peak resonance of electromagnetic oscillations located on the surface of the equipment, and its forced movement to the production well by repeated runs along with hydrocarbons, using the real-time feedback principle, thereby providing additional forced displacement of reservoir hydrocarbons, according to the invention in the reservoir through pass-through electrodes that are opposite and isolated from the casing t mineralized formation water through the alternating electrical current as a frequency resonating with the natural frequency of oscillations of molecules (dipoles) hydrocarbon reservoir, thereby effectively relaying the modulated electromagnetic oppositely directed flows to the entire length of the seam between adjacent wells. The created additional forced electromagnetic resonant displacement of hydrocarbons ensures the achievement of the indicated technical result, namely: an increase in production efficiency, a significant increase in the production rate of produced hydrocarbons, a significant increase in oil recovery factor, an increase in energy and oil mobility, an increase in oil temperature and, as a consequence, a decrease in its viscosity, which is especially important in the development of high-viscosity hydrocarbons, reducing the water content of the well fluid due to priority displacement of the productive formation is hydrocarbon fractions.

The immersion of the electrodes to the depth of the lower part of the perforation zone in these wells ensures the location of the electrodes at the level of formation water, which lies below the formation hydrocarbons. The alternating electric current passing through the electrodes through the mineralized water with a resonant frequency creates magnetic and electric fields around it mutually inducing each other (see Kalashnikov S.G. Electricity: Textbook. - 6th ed., Stereot. - M. : PHYSIATLIT, 2008) and relaying counter-directional electromagnetic waves over the entire length of the reservoir between the wells.

The physical essence of the proposed method for reducing the attenuation of electromagnetic waves in the oil reservoir consists in applying the “relay effect” of counter-directed modulated electromagnetic waves that resonate by superimposing with the natural frequencies of the molecules (dipoles) of the reservoir hydrocarbons by passing alternating current through the mineralized water also with a frequency natural vibrations of these molecules (dipoles). In the case of the use of the so-called "relay effect", an alternating current with the frequency of natural vibrations of the molecules (dipoles) of oil flowing from injection wells to those producing through saline water will emit an additional stream of electromagnetic waves of resonant frequency. Moreover, for flooded idle oil wells, which make up the lion's share of idle stock, this is guaranteed. Thus, those that set the radiation in the opposite direction to the production well, resonating with the natural frequencies of hydrocarbons (by the principle of any terrestrial antenna, only this time in a wide sector of the reservoir) will be relayed throughout the radiation sector. In other words, mineralized formation water, which has its own vibrations at the molecular level, different from the natural vibrations of hydrocarbon molecules (dipoles), will therefore not enter into resonance and purposefully move towards production wells (except for the natural depression effect) under the influence of electromagnetic radiation, selectively targeting only residual formation oil. That is, this technology implements a selective differentiated approach to the separation of the phases of the reservoir fluid: oil molecules will move with constant adjustment of peak resonance along the forced paths of peak resonance in real time (on line), controlled by control equipment from the day surface according to the feedback principle, and the molecules of produced water and the skeleton of the reservoir will not resonate and will not take the energy necessary to displace the oil. Sub-tuning technologies are widely used in dual-use defense developments in the defense industry complex of Russia in communications and homing systems.

It is known that the vibrational movement of molecules consists in a periodic change in the relative arrangement of nuclei. An important feature of this process is that it is accompanied by a change in the total electron energy (E _EL ) of the molecule. In other words, the energy E _EL can be considered as a function of the relative coordinates of the nuclei. In the simplest case of a diatomic molecule, such a coordinate is the internuclear distance r _e . Moreover, the vibrations of diatomic molecules, including water molecules (wave number ≈3700 cm ^-1 ) and hydrocarbons (wave number ≈3000 cm ^-1 ), can have a valence nature, as well as deformation, including torsional, pendulum and other vibrations (see Pentin Yu.A. Fundamentals of molecular spectroscopy./ Yu.A. Pentin, G.M. Kuramshina. - M.: Mir; Laboratory of Knowledge, 2008).

The proposed method can also be used in special cases.

So, in order to clarify the geological and geophysical parameters of the considered section of the productive formation using the receiver-generator on the surface, in the proposed method, an alternating electric current with a frequency resonating with the natural vibration frequency of the molecules is passed through the mineralized formation water between the neighboring wells in the proposed formation ( dipoles) of reservoir hydrocarbons, and only then counter-modulated electromagnetic waves begin to radiate.

To increase the efficiency of the method, modulated electromagnetic oscillations from a producing well are radiated with a controlled decrease in power from a nominal economically feasible value to zero, and modulated electromagnetic waves from an injection (or neighboring) well are radiated with a controlled increase in power from zero to a nominal economically feasible value.

It is possible to use two or more phases of an alternating current resonant frequency, when each of the electrodes is placed in different, closest to the producing wells, or two electrodes and more multiphase alternating current are placed in one well closest to the producing, while the electrode of the zero phase of alternating current is installed in production well, and all other electrodes are set so that they are directed towards the producing well.

The proposed method can also be used in other special cases:

- in the process of resuscitation of wells with periodic runs of peak controlled resonance towards the producing well, the power transmitted through the mineralized formation water of an alternating electric current having a frequency resonating with the natural vibration frequency of the molecules (dipoles) of the formation hydrocarbons is increased to economically feasible values during passage of accumulation sites residual oil or oil isolated by produced water in traps and captives;

- radiation of counter-directed modulated electromagnetic waves and the transmission of an alternating electric current having a frequency resonating with the natural frequency of the molecules (dipoles) of the reservoir hydrocarbons, consistent with it, is carried out periodically as the previously achieved production rate of the production well decreases;

- when implementing the method in a producing well and in more than one neighboring well, radiation of counter-directed modulated electromagnetic waves and the transmission of an alternating electric current having a frequency resonating with the natural frequency of the molecules (dipoles) of the formation hydrocarbons, consistent with it, is carried out fan-shaped or by clockwise or counterclockwise for uniform coverage of the entire area of the developed reservoir adjacent to the producing well;

- fan-shaped relative to the producing well, the movement of the zone of electromagnetic resonance effects on the reservoir is slowed down or stopped at the places of accumulation of residual oil, and then again continue in the optimal mode to achieve the most effective oil recovery rate;

- electromagnetic resonant effect on the molecules (dipoles) of reservoir hydrocarbons is carried out, gradually destroying cluster macromolecular formations from long-sized chains of hydrocarbons with high molecular weight in interaction with molecules of mineralized formation water to form short-sized chains of hydrocarbons with a lower molecular weight while minimizing interaction with molecules of mineralized water in frequency range from 10 ⁶ Hz to 10 ¹⁴ Hz.

The proposed method is illustrated in graphic material, which presents:

figure 1 - diagram of the implementation of the method, side view;

figure 2 is a horizontal section aa in figure 1.

The method of intensification of oil production is as follows.

In the production well 1 (Fig. 1), limited by the casing string 2, the production pump 3 (in this case, the deep-well sucker-rod pump SHGN), connected to the string of tubing 4 (tubing), is lowered and installed at a depth H of the _pump . On the surface of the wellhead, placed power station 5 which feeds a generator of electromagnetic waves 6, the descent into the wellbore before lowering extractive pump 3 and fixed in the perforation zone of _perforations at a depth H anchor 7. As an alternative, the generator of electromagnetic vibrations emitter can be placed on the surface near the well 1. Even before the installation of the electromagnetic oscillation generator 6, in the same well 1, in the lower part of the perforation zone, an electrode 8 of the zero phase of alternating current from the power station 9 is installed by a frequency generator (not shown), passing the electrode 8 through the perforation hole of the casing string 2 deep into the reservoir by the size of the bullet or torpedo perforator in the direction of the adjacent well 10, limited by the casing string 11. In this case, the electrode 8 is isolated from the casing string 2 for reduce energy losses and direct the alternating electric current exclusively through the mineralized formation water 12 of the reservoir. On the day surface, the zero phase from the electrode 8 is connected to the power plant 9 with a frequency converter (not shown) by a wire 13.

Above the mouth of a nearby (including injection) well 10, bounded by a casing string 11, a power station 14 is also located, which feeds the electromagnetic oscillation generator 15, which is fixed at the _perforation depth H using the armature 16 before the tubing string 17 (tubing) is lowered. Alternatively, the generator-emitter of electromagnetic waves can be placed on the day surface near the well 10. As for the production well 1 in the neighboring injection well 10, before installing the generator 15 of the electromagnetic waves in the lower part of the perforation zone, an alternating current phase electrode 18 is installed from the power station 9, passing it through the perforation hole of the casing string 11 deep into the reservoir by the size of a bullet or torpedo perforator in the direction of the producing well 1. When em electrode 18 is also isolated from the casing 11 to reduce energy losses and direction to alternating electric current exclusively through the mineralized formation water 12 producing formation.

In this case, the reservoir, as a conditional example, contains hydrocarbon fluid 19 (oil fraction or gas condensate), separated from the reservoir water 12 by the oil-water contact (WOC) 20.

The generators 6 and 15, included in the production process, create counter-directional oscillatory flows in the reservoir with a frequency equal to the natural frequency of the formation hydrocarbons 19. Moreover, the electromagnetic wave 21 generated by the generator 6 is directed through the reservoir from the producing well 1 towards the flow of electromagnetic waves 22 from the generator 15 located in the neighboring well 10.

On the day surface, at approximately equal distance from wells 1 and 10, control equipment (not shown) and a scan-receiver 23 are located 24. To increase the efficiency, several receiver-generators can be used along the entire length from neighboring wells to production well 1. Specified the equipment superimposes the frequencies of counter-directed oscillatory flows 21 and 22 and the natural frequency of reservoir hydrocarbons 19. In this case, the oscillation generators 6 and 15 emit counter-directed e modulated electromagnetic oscillations 21 and 22, formed by special equipment by superimposing on the carrier frequency the resonating frequencies equal in magnitude to the natural frequencies of the molecules (dipoles) of the reservoir oil 19.

In addition, alternating electric current 25 is also passed through mineralized formation water 12 from an alternating current power plant 9 with a frequency converter (not shown) also with a frequency equal to the natural frequencies of formation oil molecules (dipoles) from electrode 18 to electrode 8 with zero phase. In turn, an alternating electric current 25 with a resonant frequency, like any conductor, begins to create magnetic 26 and electric 27 fields around itself, mutually inducing each other and relaying the opposite direction electromagnetic (across the production well 1) and injection (or neighboring) well 10 fluctuations 21 and 22.

Moreover, an alternating electric current 25 with a resonant frequency passes from the phase electrode 18 to the zero phase electrode 8 (FIG. 1) not only throughout the reservoir between the production well 1 and the injection (or neighboring) well 10 below the BHC, but also between isolated clusters or residual oil 31, penetrating between them and bending them along lines 25 (Figure 2).

As a result of superposition of frequencies of counter electromagnetic radiation 21 and 22 and electromagnetic waves relaying them from passing an alternating electric current 25, which also emits resonant frequencies corresponding to the natural frequencies of the molecules (dipoles) of the reservoir oil, the peak resonance of electromagnetic waves and its controlled forced movement occur with hydrocarbons themselves 19 repeated runs to production well 1, using the principle of feedback to the mode real-time, thereby providing additional forced displacement hydrocarbon reservoir 19.

And finally, in the production process, carried out in the traditional way, into the injection well 10 using the injection pump 28 (Fig. 1) located on the surface, a stream of mineralized water 29 is injected into the reservoir through the perforations in the casing 11, reusing including formation water 12 in a closed cycle. With the established mode of production in the production well 1 in the space between the casing string 2 and the tubing string 4 at a depth of H _din installed column of borehole fluid. The indicated depth is the dynamic level of the produced fluid, which is selected using the production pump 3, receiving, in this example, reciprocating movement from the rocking machine 30.

In addition, first in the reservoir between adjacent wells 1 and 10 an alternating electric current is passed through the saline reservoir water 12 with a frequency resonating with the natural frequency of the formation hydrocarbons 19, in order to clarify the geophysical parameters of the considered section of the reservoir using the receiver-generator 23 on day surface, and then counter-modulated electromagnetic waves 21 and 22 begin to radiate.

Alternatively, the modulated electromagnetic oscillations 21 from the production well 1 emit with a controlled decrease in power from the nominal economically feasible value to zero, and the modulated electromagnetic oscillations 22 from the injection (or neighboring) well 10 emit with a controlled increase in power from zero to the same nominal value.

Further, during periodic runs of the peak controlled resonance towards the producing well 1, the power transmitted through the mineralized formation water 12 of an alternating electric current 25 having a frequency resonating with the natural frequency of the formation hydrocarbons 19 is increased to economically feasible values during passage of residual oil accumulation sites or oil, isolated formation water in traps and captures 31 (Figure 2).

Then the radiation of counter-directed modulated electromagnetic waves 21 and 22 and the transmission of an alternating electric current 25 having a frequency resonating with the natural oscillation frequency of the formation hydrocarbons 19 are coordinated with it, periodically as the production rate of the production well 1 decreases earlier.

Moreover, either one phase of an alternating electric current 25 (FIG. 1) of a resonant frequency is used, or two or more phases. So, for example, each of the electrodes 18 of three-phase alternating current resonant frequency is placed in different neighboring wells 10 with producing 1, or three electrodes 18 of three phases of alternating current 25 are installed through the perforations of the casing 11 of the injection (or neighboring) well 10 in the direction of producing 1 and one electrode 8 of the zero phase of alternating current 25 is installed through the perforation hole of the casing 2 of the producing well 1 in the direction of the injection (or neighboring) 10 so that each of them it penetrates into the reservoir by the size of a bullet or torpedo shot of a standard perforator, and each of the electrodes is guaranteed to be isolated from the casing due to its own diameters, smaller diameters of the perforations.

In addition, the radiation of counter-directed modulated electromagnetic waves 21 and 22, as well as the transmission of an alternating electric current 25 having a frequency resonating with the natural oscillation frequency of the reservoir hydrocarbons 19, when more than two adjacent wells 10 are involved, one of which is producing 1, they are carried out fan-shaped either clockwise or counter-clockwise to uniformly cover the entire area of the developed deposit adjacent to the production well 1. Alternatively, fan-shaped relative to the production of the well 1, the movement of the zone of electromagnetic resonance exposure to the reservoir is slowed down or stopped at the places of accumulation of residual oil 31 (Figure 2), and then it is continued again in the optimal mode to achieve the most effective oil recovery rate.

This method is implemented using a voltage of 380 V and a current strength of 20 A to values that are cost-effective in the development of each specific field in periodic and pulse mode. The electromagnetic resonant effect on the molecules (dipoles) of reservoir hydrocarbons is carried out, gradually destroying the cluster macromolecular formations from long-sized chains of hydrocarbons with high molecular weight in interaction with the molecules of mineralized formation water to form short-sized chains of hydrocarbons with a lower molecular weight while minimizing the interaction with the molecules of mineralized water in the next frequency range (see table):

Spectra Frequency Hz Wavelengths Accepted Units NQR 10 ⁶ ... 10 ⁹ 30 ... 300 m MHz NMR 10 ⁷ ... 10 ⁸ about 5 m MHz EPR 10 ⁹ ... 10 ¹¹ about 3 cm MHz Rotational 10 ¹⁰ ... 10 ¹² 3 cm ... 0.03 mm MHz Vibrational 10 ¹² ... 10 ¹³ 3 microns ... 3 mm cm ^-1 Electronic 10 ¹⁴ ... 10 ¹⁶ 3 ... 700 nm nm

After the separation of hydrocarbons in reservoir conditions under the influence of electromagnetic resonance radiation, further action is carried out in the frequency range corresponding to a wave number of the order of 3000 cm ^-1 , which corresponds to the eigenfrequencies of hydrocarbon molecules (dipoles).

As a result of the impact on the reservoir, the oil recovery coefficient (CIN) increases from the initial 30% to 50-60%, depending on the individual geological and geophysical features of the developed reservoir.
