摘要

"The well fluid to oil base, comprising a system emulsifier stable in temperature and non polluting".The invention relates to a fluid of oil well based, stable in temperature, no eco toxic and particularly adapted to drilling high pressure / high temperature.System itself comprises an emulsifier, comprising at least one superamida, alcoxilado, polialcoxilado or non alcoxilado, possibly associated with a non-ionic surfactant agent Co.The fluids from well to base oil, comprising this system, by obtaining inverse emulsions very stable in temperature are usable to temperatures of the order of 200 198 C.
