Abstract

QUE COMPRENDE DESCENDER LA SARTA DE PRODUCCION JUNTO CON UN DISPOSITIVO DE SELLADO DENTRO DE UN POZO Y EL POZO SE DIVIDE EN UNA CAVIDAD SUPERIOR Y UNA CAVIDAD INFERIOR CON LA AYUDA DE DICHO DISPOSITIVO DE SELLADON PARA ESTABLECER UNA CONEXION HIDRAULICA ENTRE LA APERTURA DEL POZO Y LA CAVIDAD SUPERIOR Y ENTRE LA CAVIDAD INFERIOR Y LA FORMACION PRODUCTIVA, RESPECTIVAMENTE. LA INSTALACION DEL EQUIPO Y UNA VALVULA DE RETENCION SE EJECUTAN EN EL SIGUIENTE PASO. EL FLUIDO DE LAVADO ES REEMPLAZADO POR EL FLUIDO DE LAVADO. EL EQUIPO SE PASA A TRAVES DEL DISPOSITIVO DE SELLADO Y LA CONEXION HIDRAULICA ENTRE LA APERTURA DEL POZO, LA CAVIDAD INFERIOR Y LA FORMACION PRODUCTIVA ES RESTABLECIDA A LO LARGO DEL CANAL ANULAR. EL POZO ES PROFUNDIZADO USANDO EL EQUIPO HASTA QUE OCURRA UN INFLUJO DE FLUIDOS DE FORMACION, LA PRESION DIFERENCIAL EN EL SISTEMA HIDRAULICO "APERTURA DEL PORZO-FORMACIONES PRODUCTIVAS" SE AJUSTA USANDO LA VALVULA DE RETENCION Y UN DISPOSITIVO DE PREVENCION DE EXPLOSIONES. EL EQUIPO ES RETIRADO DE LA CAVIDAD INFERIOR LUEGO DE COMPLETAR LA PROFUNDIZACION, EL DISPOSITIVO SE CIERRA DURANTE LA SEPARACION DE LA CAVIDAD DESDE LA CAVIDAD Y SE CORTA LA CONEXION HIDRAULICA ENTRE LA FORMACION PRODUCTIVA Y LA CAVIDAD SUPERIORWHICH INCLUDES DESCENDING THE PRODUCTION SARTA TOGETHER WITH A SEALING DEVICE INSIDE A WELL AND THE WELL IS DIVIDED INTO AN UPPER CAVITY AND A BOTTOM CAVITY WITH THE HELP OF SAID SEALING DEVICE TO ESTABLISH A HYDRAULIC CONNECTION AND APERTURE. UPPER CAVITY AND BETWEEN THE LOWER CAVITY AND THE PRODUCTIVE FORMATION, RESPECTIVELY. THE INSTALLATION OF THE EQUIPMENT AND A CHECK VALVE ARE PERFORMED IN THE NEXT STEP. THE WASH FLUID IS REPLACED BY THE WASH FLUID. THE EQUIPMENT IS PASSED THROUGH THE SEALING DEVICE AND THE HYDRAULIC CONNECTION BETWEEN THE WELL OPENING, THE LOWER CAVITY AND THE PRODUCTIVE FORMATION IS RESTORED ALONG THE ANNULAR CHANNEL. THE WELL IS DEEPERED USING THE EQUIPMENT UNTIL AN INFLUENCE OF FORMATION FLUIDS OCCURS, THE DIFFERENTIAL PRESSURE IN THE HYDRAULIC SYSTEM "PORTION OPENING-PRODUCTIVE FORMATIONS" IS ADJUSTED USING THE RETENTION VALVE AND A PREVENTION EXPLOSION DEVICE. THE EQUIPMENT IS REMOVED FROM THE LOWER CAVITY AFTER DEEPENING THE DEVICE IS COMPLETED, THE DEVICE IS CLOSED DURING THE CAVITY SEPARATION FROM THE CAVITY AND THE HYDRAULIC CONNECTION BETWEEN THE PRODUCTIVE FORMATION AND THE UPPER CAVITY IS CUT
