The invention concerns a temperature-stable and toxicity-free drilling fluid particularly adapted to high pressure/high temperature drilling, comprising an emulsifying system, itself including at least an alkoxylated, polyalkoxylated or non-alkoxylated superamide, optionally associated with a non-ionic cosurfactant. The oil-based drilling fluids comprising such a system, by obtaining temperature-stable reverse emulsions, can be used at temperatures up to 200 ·C.
Un fluide de puits à base d'huile, stable en température, non éco-toxique et particulièrement adapté au forage haute pression/haute température, comprend un système émulsifiant, lui-même comprenant au moins un superamide, alcoxylé, polyalcoxylé ou non alcoxylé, éventuellement associé à un agent co-tensioactif non-ionique. Les fluides de puits à base d'huile comprenant un tel système, grâce à l'obtention d'émulsions inverses très stables en température, sont utilisables jusqu'à des températures de l'ordre de 200 ~C.
