Abstract

Se describe una emulsion invertida apropiada para perforacion de pozos subterraneos, en particular pozos de petroleo y gas natural, la cual tiene una alcalinidad negativa e incluye una fase oleosa, y una fase no oleosa y un agente emulsificante el cual estabiliza la emulsion invertida bajo condiciones de alcalinidad negativa. La practica de la presente invencion permite la formulacion de fluidos para perforacion los cuales carecen de una reserva alcalina y son compatibles con los elastomeros utilizados en el equipo para perforacion. Por lo tanto los fluidos de tipo emulsion invertida de la presente invencion son bastante apropiados para perforacion de pozos de petroleo y de gas natural.
