Abstract

Método para realizar pruebas de producción de una formación petrolífera utilizando una cadena de tubos de prueba de producción que se extiende en el interior de un agujero de pozo de petróleo a partir de la superficie hasta la formación que ha de ser comprobada, incluyendo dicha cadena de tubos de pruebas de producción una válvula de prueba destinada a abrir y cerrar un canal de circulación a través de dicha cadena de tubos de pruebas de producción en respuesta a los cambios de presión en el agujero del pozo al exterior de la cadena de tubos de pruebas de producción , estando caracterizado dicho método porque incluye las operaciones que consisten en: bajar dicha cadena de tubos de pruebas de producción en el interior de dicho agujero del pozo; activar un mecanismo obturador en la extremidad de dicha cadena de tubos de prueba para aislar dicha formación del espacio anular del pozo de petróleo entre las paredes del agujero del pozo y la cadena de tubos de prueba, eleva la presión en el espacio anular del pozo; en respuesta dicho incremento de presión, abrir la válvula de prueba en el canal de circulación de la cadena de tubos de prueba para permitir que el fluido comunique a partir de la formación, a través del canal de circulación de la cadena de tubos de prueba, hasta la superficie, aflojar el incremento de presión en el espacio anular del pozo; en respuesta al aflojamiento de la presión, cerrar dicha válvula de prueba para aislar dicha formación, activar paso a paso un dispositivo de posicionamiento en una válvula de circulación situada en dicha cadena de tubos de prueba encima de dicha válvula de prueba, manteniendo dicho dispositivo de posicionamiento dicha válvula de circulación en estado cerrado hasta después de un número predeterminado de pasos; repetir los pasos de incremento y de aflojamiento de presión, un número predeterminado de veces para realizar un programa de pruebas de producción de formación, en respuesta a un aflojamiento predeterminado de la presión, abrirdicha válvula de circulación, hacer circular el fluido a través del espacio anular del pozo, de la válvula de circulación abierta y del conducto de circulación en la cadena de tubos de prueba para desplazar el fluido contenido en el canal de circulación de la cadena a de tubos de prueba, hasta la superficie, aumentar la presión en el canal de circulación de la cadena de tubos de prueba y en el espacio anular del pozo, en respuesta a dicho incremento de presión, cerrar dicha válvula de circulación y repetir los pasos de incremento y de aflojamiento de la presión un número de veces predeterminado para realizar un siguiente programa de pruebas de producción de la formación.
