    Abstract: The invention relates to a copolymer having: A) at least one monomer unit a) derived from at least one ethylenically unsaturated aliphatic monocarboxylic or polycarboxylic acid, a corresponding anhydride, or a corresponding water-soluble salt; B) at least one monomer unit b) derived from a particular sulfonated or sulfated ethylenically unsaturated ether or at least one monomer unit (b′) derived from a sulfonated ethylenically unsaturated monomer other than (b), C) at least one monomer unit (c) derived from a monomer with the average general formula [CH2═CH—CH2—R6—O—]xP(═O)(OM)3-x. The invention also relates to a method for preparing such a copolymer, an inhibitor composition including such a copolymer, and a method for inhibiting inorganic deposits in a petroleum reservoir by means of said inhibitor composition.

    Abstract translation: 本发明涉及一种共聚物,其具有:A)至少一种衍生自至少一种烯属不饱和脂族一元羧酸或多元羧酸的单体单元a),相应的酸酐或相应的水溶性盐; B)至少一种单体单元b)衍生自特定的磺化或硫酸化烯属不饱和醚或至少一种源自除(b)以外的磺化烯键式不饱和单体的单体单元(b'),C)至少一种单体单元 c)衍生自具有平均通式[CH 2 = CH-CH 2 -R 6 -O] x P(= O)(OM)3-x)的单体。 本发明还涉及一种制备这种共聚物的方法,包括这种共聚物的抑制剂组合物,以及通过所述抑制剂组合物抑制在石油储存器中的无机沉积物的方法。
