Claims (1)

Способ относится к нефтегазодобывающей промышленности и может быть использован при проведении перфорационных работ в скважинах, вскрывших продуктивные пласты. Способ включает проходку (сверление) перфорационных каналов в стенках скважины при помощи перфоратора, снабженного механизмом проходки (сверления) с режущим элементом (сверлом). В процессе проходки (сверления) на стенки перфорационного канала наносят резьбу с помощью метчика, установленного в хвостовой части режущего элемента (сверла). По окончании проходки (сверления) каждый перфорационный канал изолируют от окружающей среды обсадным патрубком с наружной резьбой, который ввинчивают в отверстие перфорационного канала. Изоляция перфорационных каналов от окружающей среды позволяет избежать межпластовых перетоков через перфорационные каналы и трещины в цементном кольце и создать надежное сообщение продуктивного пласта с пространством внутри обсадной колонны скважины.The method relates to the oil and gas industry and can be used when conducting perforation works in wells that have revealed productive formations. The method includes penetration (drilling) of perforation channels in the borehole walls using a perforator equipped with a penetration mechanism (drilling) with a cutting element (drill). In the process of penetration (drilling) on the walls of the perforation channel is applied thread with a tap installed in the tail part of the cutting element (drill). At the end of penetration (drilling), each perforation channel is isolated from the environment by a casing nozzle with an external thread, which is screwed into the hole of the perforation channel. Isolating perforations from the environment avoids cross-flow flows through perforations and cracks in the cement ring and creates a reliable communication of the reservoir with the space inside the casing of the well.
