Abstract

PROCEDIMIENTO DE PERFORACION DE POZOS CON ENSANCHE REPERFORADO EN SENTIDO ASCENDENTE.CARACTERIZ ADO POR LA EJECUCION DE LA PERFORACION EN DOS FASES, UNA PRIMERA EN SENTIDO DESCENDENTE CON VARILLAJE DE DIAMETRO REDUCIDO (1), Y OTRA SEGUNDA EN SENTIDO ASCENDENTE DE MAYOR DIAMETRO, PARA LO QUE SE UTILIZA UNA BROCA EXPANSIBLE (4) ACCIONADA A DISTANCIA POR EL PERFORADOR. SE PRECISA UN VOLUMEN MINIMO DE AIRE O AGUA PARA EL BARRIDO, AL MANTENERSE CONSTANTE EL DIAMETRO MENOR DE LA PERFORACION DESCENDENTE POR ENCIMA DE LA PERFORACION DE ENSANCHE, Y ADEMAS SE MANTIENE ELRIPIO PRODUCIDO EN EL FONDO DE LA PERFORACION (3) POR DEBAJO DE LA BROCA EXPANSIBLE, LO QUE PROTEGE EL POZO CONTRA DESPRENDIMIENTOS Y PERMITE EXTRAER EL RIPIO POR BARRIDO POR AIRE O AGUA AL ACABAR LA PERFORACION.
