POLYMÈRES SÉQUENCÉS POUR LE CONTRÔLE DU FILTRAT
The present invention relates to the use of a block polymer as fluid loss control agent in a fluid injected under pressure into an oil-bearing rock, where:the fluid comprises solid particles and/or is brought into contact with solid particles within the oil-bearing rock subsequent to its injection,the polymer comprises:a first block which is adsorbed on at least a portion of the particles; anda second block with a composition distinct from that of the first and with a weight-average molecular weight of greater than 10 000 g/mol, for example of greater than 100 000 g/mol, and which is soluble in the fluid.
