PERFORATING GUN ASSEMBLY WITH AUGER TO CONTROL WELLBORE FLUID DYNAMICS

摘要

A downhole tool used in the pressure isolation of adjacent subterranean f ormations. The downhole tool may comprise flow restriction devices along the outer circumference for impeding flow along the length of the tool. The too l may further comprise a perforating gun and an accumulator. Impeding flow a long the length of the tool provides a dynamic flow restriction within the w ellbore that precludes fluid flowing from one subterranean zone to an adjace nt zone.
