AQUEOUS FLUID COMPRISING A BORONATE POLYMER AND A LIGAND POLYMER AND USE THEREOF IN THE EXPLOITATION OF OIL AND GAS DEPOSITS

摘要

The invention relates to an aqueous fluid used in the exploitation of deposits of oil and gas, comprising at least one boronate polymer with at least one boronate function or a precursor, at least one ligand polymer with at least two groups which may react with the boronate group(s) or precursor(s), said groups having a cis arrangement and carried on vicinal atoms or two atoms separated by a supplementary atom, at least one salt which is soluble in the fluid, at a level of at least 0.01 % by weight with relation to the weight of the fluid and less than the limit of solubility of the salt(s) in said fluid. The invention further relates to the use of said fluid as fracturing fluid or as drilling fluid.
