Abstract

Procédé perfectionné pour traiter des solutions aqueuses de polyacrylamides partiellement hydrolysés destinées à être injectées dans des gisements de pétrole pour l'exraction par noyage. On expose les solutions de polyacrylamides à une concentration inférieure à 1 kg/m**3 à des gradients de cisaillement de 20 000 à 50 000 s-**1. Les solutions traitées conformément à l'invention ont des propriétés de viscosité beaucoup plus favorables que les solutions non traitées.An improved process for treating aqueous solutions of partially hydrolyzed polyacrylamides intended for injection into petroleum fields for flooding extraction. Polyacrylamide solutions at a concentration of less than 1 kg / m ** 3 are exposed to shear gradients of 20,000 to 50,000 s - ** 1. Solutions treated in accordance with the invention have much more favorable viscosity properties than untreated solutions.
