Abstract

L'INVENTION A TRAIT AU FORAGE. ELLE CONCERNE UNE COMPOSITION AQUEUSE DE LIQUIDE DE FORAGE, UN AGENT LIMITANT LA FILTRATION DESTINE A ETRE UTILISE DANS CE LIQUIDE AQUEUX DE FORAGE ET UN PROCEDE DE PRODUCTION D'UN DEPOT FILTRANT SUR LA PAROI D'UN PUITS EN VUE DE REDUIRE LA PERTE PAR FILTRATION DU LIQUIDE DE FORAGE. ON UTILISE, CONFORMEMENT A L'INVENTION, UN COPOLYMERE 1 D'UN ACIDE (METH)-ACRYLAMIDO-ALKYL-SULFONIQUE OU D'UN SEL DE METAL ALCALIN DE CET ACIDE ET 2 D'UN (METH)-ACRYLAMIDE OU D'UN N-ALKYL-(METH)-ACRYLAMIDE. LE COPOLYMERE PEUT ETRE RETICULE AVEC UN SEL D'AMMONIUM QUATERNAIRE.THE INVENTION IS ABOUT DRILLING. IT CONCERNS AN AQUEOUS COMPOSITION OF A DRILLING LIQUID, AN AGENT LIMITING FILTRATION FOR USE IN THIS AQUEOUS DRILLING LIQUID AND A PROCESS FOR PRODUCING A FILTERING DEPOSIT ON THE WELL WALL WITH A VIEW TO REDUCING LOSS BY FILTRATION DRILLING FLUID. IN ACCORDANCE WITH THE INVENTION, A COPOLYMER 1 OF A (METH) -ACRYLAMIDO-ALKYL-SULPHONIC ACID OR OF AN ALKALINE METAL SALT OF THIS ACID AND 2 OF A (METH) -ACRYLAMIDE OR A N-ALKYL- (METH) -ACRYLAMIDE. THE COPOLYMER MAY BE CROSS-LINKED WITH A QUATERNARY AMMONIUM SALT.
