Fluidizing Agent, not impurificante, Drilling Fluid, based on fresh or Saline Water

摘要

The present Invention relates to fluidizing agent for drilling fluids aqueous saline or not,The Group of Polymers and / or copolymers of acidic functions; characterized by the fact that, in order to preserve their rheological characteristics in these Fluids.Even in the extreme conditions of temperature and pressure prevailing in the Mud Drilling depthThe fluidizing Agent is a Salt of these Polymers and / or copolymers in which at least one salificador corresponds to a metal cation electronegativity according to Pauling at least equal to 0.95 and preferably greater than 1.
