| titleOfInvention | AQUEOUS POLYMER SOLUTIONS VISCOSING REVERSIBLY OR TRANSFORMING IN REVERSIBLE GEL UNDER THE EFFECT OF A SHEAR |
| abstract | Water-based fluids which are of a nature to viscosify under shear or to gel or form a gel under shear, which are obtained by dissolving polymers in an aqueous phase, these polymers comprising 3 types of sites: non- sites ionic water-soluble at the temperature considered, ionic sites and hydrophobic sites at the temperature considered. These three types of sites must be distributed or distributed according to a random distribution along the polymer chain. A slight "block" distribution is acceptable although it is not preferred, but a true "block" distribution of the above sites is not suitable. A particularly preferred characteristic, for oil well applications, resides in the use of sites having an LCST (“Lower Critical Solution Temperature”) behavior (that is to say a low critical solution temperature) instead of hydrophobic sites. At temperatures below the LCST, the sites are hydrophilic. |
