Abstract

La presente invención se refiere a metodo para inhibir la corrosión de superficies metálicas de equipo para excavar en pozos para la recuperación de fluídos naturales de reservorios naturales, caracterizado por detener la producción de los fluídos naturales inyectando una composición, que comprende: una resina epóxica; un agente curante para la resina epóxica, un diluyente de hidrocarburo y un alcohol, en donde la proporción en peso del agente curante y la resina epóxica es de aproximadamente de 1000:1 a aproximadamente 1:500 y el alcohol está presente en una cantidad de alrededor de 1 a aproximadamente 99 or ciento en peso, basado en el peso de la composición; regresar el pozo a producción, motivando así que la composición regrese con los fluídos naturales y se deposite como un inhibidor de la corrosión en forma de una película inhibidora de la corrosión dirigido a la superficie metálica con la cual se pone en contacto.The present invention relates to a method of inhibiting the corrosion of metal surfaces of equipment for digging in wells for the recovery of natural fluids from natural reservoirs, characterized by stopping the production of natural fluids by injecting a composition, comprising: an epoxy resin; a curing agent for the epoxy resin, a hydrocarbon diluent and an alcohol, wherein the weight ratio of the curing agent and the epoxy resin is from about 1000: 1 to about 1: 500 and the alcohol is present in an amount of about 1 to about 99 or percent by weight, based on the weight of the composition; return the well to production, thereby motivating the composition to return to natural fluids and deposit as a corrosion inhibitor in the form of a corrosion inhibiting film directed at the metal surface with which it is contacted.
