Abstract

Se proveen un metodo y un aparato para recolectar datos en profundidad durante una perforacion a traves de una herramienta en profundidad. Se crea una diferencia de presion por la diferencia entre la presion interna de los fluidos que atraviesan la herramienta en profundidad y la presion anular en el pozo de perforacion. El aparato incluye un cuello de perforacion que se conecta a la perforacion en profundidad, y tiene una abertura que se extiende hacia el interior de una camara. Se coloca un piston en la camara con una varilla que se extiende hacia la abertura. El piston se desplaza entre una posicion de cerrado, donde la varilla ocupa la abertura, y una posicion de abierto, donde la varilla se retrae al interior de la camara para formar una cavidad a fin de recibir los fluidos de la profundidad. Se coloca un sensor en la varilla para recolectar los datos de los fluidos en la cavidad. El aparato tambien puede estar provisto de una sonda y/o un circuito hidraulico para facilitar la recoleccion de datos.
