Abstract

METODO PARA LA PRODUCCION DE FLUIDOS ACUOSOS DE PERFORACION. CONSISTE EN AÑADIR A UNA MEZCLA DE AGUA Y ARCILLA, ENVEJECIDA DURANTE AL MENOS UNA NOCHE Y CUYO PH SE HA AJUSTADO A 10, UN TERPOLIMERO OBTENIDO POR MEZCLA DE 30 A 50 PARTES, EN MOLES, DE ANHIDRIDO MALEICO CON 1 A 21 PARTES DE PEROXIDO DE DI-T-BUTILO, EN UN DISOLVENTE ORGANICO INERTE, CALENTAMIENTO Y TRATAMIENTO CON 10 A 40 PARTES DE ESTIRENO Y DE 10 A 60 PARTES DE ACRILAMIDA COMO CORRIENTES SEPARADAS A UNA VELOCIDAD ADECUADA PARA COMPLETAR LA ADICION EN UN PERIODO DE TIEMPO DE 15 A 180 MINUTOS. MEZCLAR BIEN AMBOS COMPONENTES Y REAJUSTAR EL PH DEL PRODUCTO A 10,5. ESTOS FLUIDOS TIENEN APLICACION EN LOS POZOS PERFORADOS POR EL METODO ROTATORIO.
