COPOLYMER UNDERSTANDING MONOCHERS DERIVED FROM MONOCARBOXYLIC OR POLYCARBOXYLIC ALIFATIC ACID, INHIBITIVE COMPOSITION OF INORGANIC TANKS AND INHORGANIC TANKS INHIBITION PROCESS IN A PET RESERVOIR |
| abstract |
copolymer comprising monomers derived from monocarboxylic or polycarboxylic aliphatic acid, inhibiting composition of inorganic deposits and process for inhibiting inorganic deposits in an oil reservoir the present invention relates to a copolymer comprising: a) at least one monomer unit a) derived at least one ethylenically unsaturated monocarboxylic or polycarboxylic aliphatic acid, a corresponding anhydride or a corresponding water-soluble salt; b) at least one monomer unit b) derived from a special sulfonated or sulfated ethylenically unsaturated ether or at least one monomer unit (b1) derived from an ethylenically unsaturated sulfonated monomer, other than (b), c) at least one monomer unit ( c) derived from a monomer of general formula [ch2 = ch-ch2-r6-o-] xp (= o) (om) 3-x. the invention also relates to a process for preparing such a copolymer, an inhibitory composition comprising such a copolymer and a process for inhibiting inorganic deposits within an oil reservoir with the aid of said inhibitory composition. |
