Abstract

1, СПОСОБ ОТБОРА КЕРНА в монолитных , ненарушенных горных породах, включающий разрушение пород по кольцу с помощью электроимпульсных разр дов, последующий срыв керна и извлечение его на поверхность, отличающийс  тем, что, с целью повышени  надежности отбора керна , срыв производ т путем повышени  энергии электроимпульсных разр дов не менее, чем на 30%, посравнению с энергией , необходимой дл  разрушени  пород по кольцу. 2.Способ .по п,1, от ли на ю щ и и с   тем, что повышение энергии электроимпульсных разр дов осуществл ют. путём формировани  электроимпульсных разр дов с замедленной скоростью выделени  энергии. 3.Способ по П.2, отличающийс  тем. что формирование электроимпульсных разр дов с замедленной скоростью выделени  энергии осуществл ют путем повышени  емкости в разр де не менее чем на 30% по сравнению с первоначальной. «1, CORRECTION METHOD in monolithic, undisturbed rocks, including destruction of rocks in a ring with the help of electric pulse discharges, subsequent disruption of the core and its extraction to the surface, characterized in that, in order to increase the reliability of coring, the disruption is performed by increasing energy electrical pulse discharges of not less than 30%, in comparison with the energy required to destroy rocks in a ring. (2) The method according to claim 1, is independent of the fact that the energy of the electric pulse discharges is increased. by generating electropulse discharges with a slower rate of energy release. 3. The method according to claim 2, characterized in that. that the formation of electropulse discharges with a slower rate of energy release is carried out by increasing the capacitance in the discharge by at least 30% compared to the initial one.
