Abstract
Esta invención está relacionada con una nueva metodología para la generación de espuma preformada en superficie, la cual consiste en la mezcla de agua, nitrógeno gaseoso (N2) y agente espumante en la cabeza del pozo, de forma tal que se produzca un choque de flujos, para obtener la mayor energía de mezcla y generar una espuma de muy alta viscosidad y un mayor número de burbuja por unidad de volumen (textura, que pueda fluir por la tubería del pozo y permita el bloqueo de zonas de altas permeabilidades cuando llegue a condiciones de yacimiento, lo cual desviada la inyección de vapor posteriormente hacia zonas de baja permeabilidad y con alta saturación de aceite.This invention is related to a new methodology for the generation of preformed foam on the surface, which consists of the mixture of water, nitrogen gas (N2) and foaming agent at the head of the well, in such a way that a flow shock occurs. , to obtain the highest mixing energy and generate a foam of very high viscosity and a greater number of bubbles per unit volume (texture, which can flow through the well pipe and allows the blocking of areas of high permeability when it reaches conditions reservoir, which later diverted steam injection to areas of low permeability and high oil saturation.
