Abstract

"MéTODO DE ESTIMULAçãO POR ACIDIFICAçãO USANDO-SE AGENTE DE FORMAçãO DE GEL VISCOELáSTICO". A presente invenção refere-se a um método de acidificação de uma formação substerrânea que envolve o uso de uma composição contendo uma solução de um tensoativo de óxido de amidoamina viscoelástico e uma solução acidificante contendo HF. A composição tipicamente contém de cerca de 0,1 a cerca de 8% em peso de solução tensoativo e de cerca de 92 a cerca de 99,9% em peso de solução acidificante contendo HF. A composição é bombeada para dentro da formação subterrânea. Uma vez que o ácido reage, a composição viscosifica e torna um agente de autodesvio criado in situ. Quando o ácido é ulteriormente gasto, a viscosidade de fluido baixa finalmente retornando para um estado de baixa viscosidade, permitindo limpeza fácil. O processo permite acidificação seletiva de zonas menos permeáveis da formação e estimulação mais uniforme da formação portadora de hidrocarboneto."ACIDIFICATION STIMULATION METHOD USING VISCOELASTIC GEL FORMING AGENT". The present invention relates to a method of acidifying an underground formation involving the use of a composition containing a viscoelastic amidoamine oxide surfactant solution and an HF containing acidifying solution. The composition typically contains from about 0.1 to about 8% by weight of surfactant solution and from about 92 to about 99.9% by weight of HF-containing acidifying solution. The composition is pumped into the underground formation. Once the acid reacts, the composition viscosifies and makes a self-diverting agent created in situ. When acid is subsequently spent, the low fluid viscosity finally returns to a low viscosity state, allowing for easy cleaning. The process allows selective acidification of less permeable zones of formation and more uniform stimulation of hydrocarbon carrier formation.
