"Fluid tamponador for capping a zone of underground formation which surrounds a drill drilling.Method for the preparation of the fluid tamponador and method of sealing of a zone of loss by movement in a bore of the well. A fluid tamponador for capping a zone of underground formation which surrounds a drill drilling, comprising an oil phase containing an oil, an emulsifier, and 2.4 the 4kg of cement per liter of oil and an aqueous phase containing water and 12 to 16 of a polysaccharide per litre of water.Where the volume ratio of oil to water varies in the range of 20: 80 to 25: 75.Under the action of shearing, the emulsion is used so that droplets of the emulsion release cement in water phase.Thereby providing metallic ion divalente to lattice with polysaccharides and form a gel structure.
