摘要: A temperature-stable, non eco-toxic oil-base well fluid that is particularly suitable for high pressure/high temperature drilling comprises an emulsification system comprising at least one superamide may or not be polyalkoxylated, optionally associated with a non-ionic co-surfactant. The such can used temperatures of up to about 200° C. due the production highly temperature-stable reverse emulsions.
