| titleOfInvention | Novel method for the treatment of rock formations and novel polyampholytes |
| abstract | The invention relates to a method for the treatment of rock formations which may or may not be underground and, more particularly, of oil or gas production wells, water-injection wells intended to flood hydrocarbon (oil or gas) reservoirs or gas mines or gas storage wells. The invention is characterized in that it includes a step comprising the injection, into said rock formation or well, of a microgel obtained by dilution in water of a self-invertible inverse latex or of a self-invertible inverse microlatex of a crosslinked polyelectrolyte, obtained by copolymerization, in the presence of a crosslinking agent of partially- or totally-salified free 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid, with at least one cationic monomer chosen from: 2,N,N,N-tetramethyl-2-[(1-oxo-2-propenyl)amino]propanammonium chloride; N,N,N-trimethyl-3-[(1-oxo-2-propenyl)amino]propanammonium chloride; diallyldimethylammonium chloride; N,N,N-trimethyl-2-[(1-oxo-2-propenyl)]ethanammonium chloride; N,N,N-trimethyl-2-[(1-oxo-2-methyl-2-propenyl)]ethanammonium chloride; or N,N,N-trimethyl-3-[(1-oxo-2-methyl-2-propenyl)amino]propanammonium chloride; and with at least one neutral monomer chosen from: acrylamide; N,N-dimethylacrylamide; N-[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]propenamide; or 2-hydroxyethyl acrylate. |
