Abstract

SE REFIERE A UN METODO PARA PERFORAR Y TRATAR INTERVALOS MULTIPLES DE UNA O MAS FORMACIONES SUBTERRANEAS INTERSECTADAS POR UN POZO DE SONDEO, QUE COMPRENDE: 1) DESPLEGAR UN MONTAJE DE BARRENO TENDIDO (MBT), QUE CUENTA CON UN DISPOSITIVO DE PERFORACION Y UN MECANISMO SELLADOR, DESDE UNA CADENA DE TUBERIA DENTRO DEL POZO; 2) PERFORAR POR LO MENOS UN INTERVALO DE UNA O MAS FORMACIONES SUBTERRANEAS USANDO EL DISPOSITIVO DE PERFORACION ; 3) COLOCAR EL MBT DENTRO DEL POZO DE SONDEO Y ACTIVAR EL MECANISMO SELLADOR DE MANERA QUE SE ESTABLECE UN SELLO HIDRAULICO DEBAJO DEL INTERVALO PERFORADO; 4) BOMBEAR UN FLUIDO TRATANTE HACIA LA CORONA CIRCULAR ENTRE LA CADENA DE TUBERIA Y EL POZO DE SONDEO Y HACIA DENTRO DE LAS PERFORACIONES CREADAS POR EL DISPOSITIVO DE PERFORACION, SIN REMOVER DICHO DISPOSITIVO DESDE EL POZO DE SONDEO; 5) LIBERAR EL MECANISMO SELLADOR; Y 6) REPETIR LAS ETAPAS (2) Y (5) POR LO MENOS UN INTERVALO ADICIONAL. SE REFIERE TAMBIEN A UN SISTEMA DE TRATAMIENTO DE ESTIMULACION PARA LLEVAR A CABO EL METODO ANTERIORMENTE DESCRITO, QUE COMPRENDE: a) UN FLUIDO TRATANTE; b) UN MEDIO DE DESPLIEGUE EXTENDIDO DENTRO DEL POZO DE SONDEO; Y, c) UN MONTAJE DE BARRENO TENDIDOIT REFERS TO A METHOD TO DRILL AND TREAT MULTIPLE INTERVALS OF ONE OR MORE UNDERGROUND FORMATIONS INTERSECTED BY A BORE WELL, INCLUDING: 1) DEPLOYING A TENDED HOLE ASSEMBLY (MBT), WHICH HAS A SEALING DEVICE AND PERFORMING DEVICE , FROM A CHAIN OF PIPELINE INSIDE THE WELL; 2) DRILL AT LEAST ONE INTERVAL OF ONE OR MORE UNDERGROUND FORMATIONS USING THE DRILLING DEVICE; 3) PLACE THE MBT INSIDE THE BORE WELL AND ACTIVATE THE SEALING MECHANISM SO THAT A HYDRAULIC SEAL IS ESTABLISHED BELOW THE PERFORATED INTERVAL; 4) PUMP A TREATING FLUID TOWARDS THE CIRCULAR CROWN BETWEEN THE PIPE CHAIN AND THE DRILLING WELL AND INTO THE PERFORATIONS CREATED BY THE DRILLING DEVICE, WITHOUT REMOVING SAID DEVICE FROM THE DRILLING WELL; 5) RELEASE THE SEALING MECHANISM; AND 6) REPEAT STEPS (2) AND (5) AT LEAST ONE ADDITIONAL INTERVAL. IT ALSO REFERS TO A STIMULATION TREATMENT SYSTEM TO CARRY OUT THE ABOVE-DESCRIBED METHOD, WHICH INCLUDES: a) A TREATMENT FLUID; b) A MEANS OF DEPLOYMENT EXTENDED INSIDE THE DRILL WELL; AND, c) A LAYING HOLE ASSEMBLY
