Abstract:
The invention belongs to the oil industry and can be used for enhanced oil recovery by formations under complicated mining and geological conditions. The method of repeated completion of the production formations by helicoid perforation includes perforation, which is performed by moving the perforator along well axis and simultaneously rotating it around its axis with making perforation channels, provided that the speeds of movement and rotation of the perforator are selected based on the condition that the perforation obtained as a result is a helicoid with creation an empty space in the processed formation.
