Abstract

COMPOSIçãO DE ACIDIFICAçãO PARA FORMAçõES SUBTERRâNEAS E MéTODO PARA TRATAR UMA FORMAçãO SUBTERRâNEA". A presente invenção se refere à composições de acidificação para serem usadas em formações subterrâneas de petróleo, de água ou de gás, visando o aumento de permeabilidade das ditas formações subterrâneas de petróleo, ou de água ou de gás. Mais particularmente, a invenção se refere à composições de acidificação contendo uma mistura de ácidos orgânicos e inorgânicos, as quais possuem uma ação de proteção do inibidor de corrosão. A invenção contempla ainda um método para tratar uma formação subterrânea.ACIDIFICATION COMPOSITION FOR UNDERGROUND FORMATIONS AND METHOD FOR TREATING A UNDERGROUND FORMATION ". The present invention relates to acidification compositions for use in underground petroleum, water or gas formations for the purpose of increasing the permeability of said underground petroleum formations. More particularly, the invention relates to acidification compositions containing a mixture of organic and inorganic acids which have a corrosion inhibitor protecting action.The invention further contemplates a method for treating a formation underground.
