METHOD FOR DEVELOPING OIL AND GAS FIELDS USING HIGH-POWER LASER RADIATION FOR MORE COMPLETE OIL AND GAS EXTRACTION

摘要

The invention relates to the mining industry and can be used for the more complete extraction of all types of oil and gas and other mineral resources using high-power laser radiation in the production process. In the method for developing oil and gas fields using high-power laser radiation for more complete oil and gas extraction, according to which producing formations are opened up in predetermined regions of the wellbores by means of the cutting or perforation of the material of the wellbore casing strings using high-power laser radiation with the subsequent evaporation of the solid and liquid phases of substances contained in the formations and in the matrix rock through these openings, optical fibre cables with light energy-emitting working heads on the ends thereof are used as energy transmitting devices, high-power lasers at the surface are coupled to the optical fibres (light-emitting diodes) of the optical fibre cables, and regions with a predetermined high temperature and a high pore pressure are generated in the formations in order to increase the degree of extraction of oil and gas, the process of treating the field formations with high-power laser radiation is repeated multiple times with the necessary time intervals therebetween, wherein a plurality of sectors which are mutually offset from one another by a certain angle are irradiated simultaneously, the beams in each sector diverging at a given angle,
