摘要：Suppressing passage of an aqueous fluid in a subterranean formation inpreference to passage of an oleaginous fluid can often be desirable. Methods forsuppressing the passage of an aqueous fluid in a subterranean formation, particularly acarbonate formation, can comprise: providing a treatment fluid comprising a carrier fluidand a relative permeability modifier comprising a reaction product of 1) an acrylamidepolymer, any copolymer thereof, any derivative thereof, any salt thereof, or anycombination thereof, and 2) a plurality of amine-containing compounds or any saltthereof, each amine-containing compound containing a primary amine, a secondary amine,or any combination thereof, and the amine-containing compounds being randomlyreacted with at least a portion of the amide groups of the acrylamide polymer; andintroducing the treatment fluid into a subterranean formation.
