Abstract

The present invention relates to a method for exploiting gas and oil fields and for increasing gas and crude oil output. This method comprises placing electrodes into the wells bored in the gas or oil field, sealing the wells with packers and supplying a high-voltage alternative, direct or pulse current to said electrodes. This method is characterised in that the wells are sealed with packers at the top of the formation. After supplying the electrical current, this method includes adjusting the current and voltage parameters and/or the mutual location of the electrodes in order to create an electrical arc between the electrodes located in one or more wells or between electrodes located in two adjacent wells.

In a well in a non-gas field, oil reservoirs are placed down to the soil of non-contaminated (gas-bearing) reservoir electrodes, then geometize the wells with the help of well-known devices - packages at the level of formations, and give to alternating electrodes, direct or pulsed electric current of high voltage. Then the parameters of the current and voltage values and/or the mutual arrangement of the electrodes are adjusted to ensure the occurrence of an electric arc between the electrodes located in at least one well or between the electrodes of two adjacent wells.

In this case, it is advisable to ignite the electric arc by melting the insert between the electrodes or by separating the contacts of the electrodes in this well with a simultaneous increase in the voltage of the supplied current. If the entire layer is being processed, then it is advisable to ignite the electric arc by slightly igniting electrical layer of the formation or by breaking the gaps between the electrodes of two neighboring wells at higher and higher altitudes tension on them.

The sequence of connecting new wells to the process of burning electric arcs in formations is determined either based on the possibility of uniform processing of the entire area of formations in a given location, or in cases of complex geological conditions of formation occurrence locations based on the features of the bedding of the layers. The amount of internal vibration of electric arcs at different locations will be different depending on the physical and mechanical characteristics, electrical analysis of plastics, composition and type of mineral, stress-depot the state of themselves layers and the rocks enclosing them, geological conditions of the layers’ occurrence and a number of other factors. In each specific case, during the burning of electric arcs between adjacent wells in the reservoirs, an experimental method is established with simultaneous measurements of internal reservoir pressure and temperature, as well as by laboratory and mathematical modeling. this process under given conditions to achieve maximum effect and increase the degree of extraction of useful minerals from the formations. In necessary cases, multiple processing of formations with electric arcs is possible through necessary time intervals after intensive extraction of minerals from formations, for example, to maintain specified or necessary pressures and temperatures of oil and gas in formations for most of them are pumped out of the field. This is especially important in the case of production from viscous oil formations or when pumping gas from moisture-saturated wells with low formation pressure, since gas wells in such cases can self-seize with water coming from the formations together with the gas. 4

In Fig. 1 digit 5 denotes packages with which wells A and B are reliably geometized to prevent access to acid air into the layer during the burning process of electric arcs. In addition, packers serve to extinguish the electrohydraulic shock in the well that occurs when an arc is ignited in each individual well. The packers are extracted from the wells after the completion of the formation treatment with electric arcs between adjacent wells, and before that they also serve as plugs for oil and gas, the pressure and temperature of the wells after the formation treatment with electric arcs increases sharply.

In these cases, the proposed method is used before the start of exploitation of the new location. Moreover, in a number of areas where the formation has already been processed by electric arcs, industrial production can begin, and in the remaining areas of the formation, processing can continue as new wells are drilled into the formation in parallel with wells already operating for oil or gas production. The second situation is when the flow rate of existing and intensively exploited wells in the past has significantly dropped at the initial site, but it is known that oil and gas reserves are still significant and it is necessary to increase the internal pressure and temperature to extract the remaining reserves from the subsoil. In both situations, wells drilled to the reservoir soil are sealed with packers 5 at the reservoir roof level and electrodes 7 are preliminarily placed in them. If it is necessary to ignite an electric arc only in one well B, then electrodes 7 are connected to each other by melting insert, designed for a certain current value, and then high voltage current is applied to them and when the voltage and current increase, after the insert melts, an arc is ignited between the electrodes. If it is necessary to ignite an electric arc between two adjacent wells of a site, then the electrodes 7 are placed in the layer of the formation that has the best electrical conductivity and provide reliable contact with this layer. In the overwhelming majority of cases, this layer is an aquifer lying in the formation soil. In this case, the electrodes 7 are placed in water filling the well in a mixture with oil and gas in a state up to the lower end of the packer. Oil, as a lighter component of the mixture, appears at the top of the liquid column, and water - at the bottom. When high-voltage current is supplied to electric wires 7 through high-voltage connecting cables 1 1 from mobile pulse voltage sources and powerful capacitors 12, in the event of ignition 7

In the case when one of the electrodes is the casing pipes 6 of the well, after high voltage current is applied to the electrode 7 They lead through the casing pipes 6 and make contact between them, as a result of which an electric arc 8 appears in the well Α. When an electric arc is ignited between two adjacent wells, the voltage on the electrodes of the adjacent wells is increased to such a degree that a breakdown of the formation occurs along the layer with maximum electrical conductivity (water layer), or pre- They heat up the most conductive layer of the formation and, while maintaining the required voltage, an electric arc 9 is also ignited between wells A and B with a plasma temperature in it of up to tens of thousands of degrees Celsius, depending on the value of the nominal currents. The rate of voltage increase and its maximum value depend on the parameters of the electric circuit. The greater the distance between the electrodes of individual wells, the greater will be the maximum value of the arc-setting voltage. With increasing pressure, the plasma temperature increases. For up to 10,000 o the arc burns in a diffuse form, and for larger arcs - in a compressed form. An electric arc is one of the types of discharge in gas or papak, which is characterized by a large density of the arc, a small voltage drop in the arc barrel and a high temperature. Since any electrical circuit has inductance and capacitance, by including additional large inductances and capacitances on the ground surface in this circuit, significant magnetic energy is stored, which is released when the circuit is opened. alternating current is released and converted into thermal energy, part of it is converted into other types of energy, and the resulting electric arc and the environment surrounding it are energy absorbers. Therefore, in the environment surrounding the arc, evaporation of liquid and solid components of the formation and the enclosing gas occurs in relatively short periods of time at very high 8

All this leads to a significant increase in the internal pressure and an even greater increase in the temperature of the plasma in the burning arc, so that arcs of very high pressure and temperature burn in the plastic, which move in the internal space in a given order and sequence, processing it over the entire or a given part of the area of the site, which leads to a sharp change in the stress-strain and temperature state of the mineral formation and the host rock. The system of cracks and cracks changes, voids and free spaces appear in the layer due to the evaporation of solid and liquid phases, which after the arcs are extinguished will lead to another transfer of stresses from the hot pressure and this will also have a positive effect on the increase oil and gas inflow into wells. Oil viscosity will be significantly reduced, resinous and paraffin components of oil in shale and cracks will be burned out.

But, in addition to this, the proposed method has a whole series of significant advantages.

It can be successfully used for underground gasification of coal seams, which will significantly increase the degree of coal extraction from the earth's interior, will significantly reduce pollution of the environment with harmful exhaust gases from the mining industry (pollution dumps, pumped-out underground waters from wells and mining operations with a high content of sulfur and other harmful impurities that fall into water bodies) and improve the ecology of territories where mineral resources are found. With the help of this method it is also possible to destroy underground burial grounds and cemeteries with wastes of harmful radioactive and chemical substances, burning and evaporating them underground in the plasma of electric arcs without access to oxygen, and thereby preventing them dispersal by underground waters to other places. The proposed method can achieve the release into underground workings from ore veins, bodies and lenses of metals, such as gold, silver and others, possessing very high electrical conductivity.
