перфорация с ограниченным доступом для ГРП(Limited-entry strategy means choosing the perforation diameter and the number of perforations in every zone to create a certain pressure differential across the perforations, so that anticipated injection flow rate produces sufficient flow rate and fracture net pressure through each perforation to adequately stimulate every zone. Kenny Gray)
