Abstract

"PROCESSO E COMPOSIçãO PARA REMOçãO DE DANO PARAFìNICO COM AUXìLIO DE ESPUMA EM FORMAçõES PRODUTORAS DE PETRóLEO E MéTODO DE RESTAURAçãO DA PRODUçãO DE POçOS". é descrito um processo para restaurar a produção de formações produtoras, onde a remoção do dano causado por depósitos parafínicos é feita por uma espuma gerada in situ por um SGN. A composição compreende sais inorgânicos como cloreto de amónio e nitrito de sódio, um viscosificante polimérico, um agente redutor de ponto de fluidez e um ativador persulfato de sódio, gerador de íons H^ +^, para catalisar a reação de geração de nitrogênio e calor. Em contato com o calor da formação a reação ocorre com formação de espuma, calor e gás nitrogênio. São igualmente descritas a composição utilizada para gerar a espuma e o método de restauração da produção de poços por remoção de dano parafínico, utilizando a composição da invenção."PROCESS AND COMPOSITION FOR PARAMIC DAMAGE REMOVAL WITH FOAM AID IN OIL PRODUCER TRAINING AND WELL PRODUCTION RESTORATION METHOD". A process for restoring production of producing formations is described, where the removal of damage caused by paraffin deposits is done by a foam generated in situ by an SGN. The composition comprises inorganic salts such as ammonium chloride and sodium nitrite, a polymeric viscosifier, a pour point reducing agent and a sodium persulfate activator, H ^ + ^ ion generator, to catalyze the nitrogen and heat generation reaction. . In contact with heat formation reaction occurs with foaming, heat and nitrogen gas. Also disclosed are the foam-making composition and the method of restoring paraffin damage removal well production using the composition of the invention.
