Inorganic deposit inhibitors, in particular in oil wells, particularly in high pressure/high temperature conditions |
| abstract |
The invention concerns inorganic deposit inhibitors, in particular in oil wells. Said inhibitors comprise a water soluble copolymer consisting of (in mol % of polymerised monomers): a) 5 to 95% of styrenesulphonic acid or one of its salts; b) 5 to 95% of vinylsulphonic acid or one of its salts; c) 0 to 20% of one or several non-ionizable unsaturated monomers. They are particularly efficient against calcium carbonate and/or barium sulphate deposits. They are capable of being used in accordance with a so-called squeeze process in HP/MT conditions with desorption compatible with the desired treatment duration. |
