The present invention concerns a method for inhibiting the permeation of water in an extraction well of a hydrocarbon fluid from an underground reservoir which comprises: a) injecting into said reservoir, at least one treatment fluid comprising at least one emulsion or one dispersion in an organic solvent of at least one copolymer from: - a first monomer selected from an acrylic monomer or methacrylic monomer, and - a second monomer comprising at least one ethylene unsaturation and at least one polyoxyethylene chain. The present invention also concerns emulsions and dispersions of copolymers usable in the above-mentioned method. 本发明涉及种抑制水渗透到来自地下储层的烃类流体的抽提井中的方法，该方法包括：a)向所述储层中注入至少种处理流体，所述处理流体包含至少种共聚物在有机溶剂中的至少种乳液或种分散体，所述共聚物来自：-选自丙烯酸类单体或甲基丙烯酸类单体的第单体，和-包含至少个乙烯不饱和度和至少个聚氧乙烯链的第二单体。本发明还涉及可用于上述方法的共聚物的乳液和分散体。
