Abstract

APARATO DE VALVULA UTILIZADO PARA CONTROLAR LA CIRCULACION DE FLUIDOS EN UN POZO DE SONDEO DURANTE EL ENSAYO CON BARRA DE PERFORACION. CONSTA DE ALOJAMIENTOS TUBULARES (9, 10) QUE DEFINEN UN PASAJE DE CIRCULACION (12) DE FLUIDOS; DE UN ELEMENTO DE VALVULA ESFERICA (14) QUE GIRA ALREDEDOR DE UN EJE TRANSVERSAL AL PASAJE DE CIRCULACION (12), ENTRE UNA POSICION ABIERTA Y UNA POSICION CERRADA; DE UN ASIENTO DE VALVULA (13) QUE RODEA A DICHO PASAJE DE CIRCULACION (12), PROVISTO DE UNA SUPERFICIE DE ASIENTO Y DE UN MEDIO DE SELLADO QUE COACTUAN CON EL ELEMENTO DE VALVULA ESFERICA (14) EN LA POSICION CERRADA, BLOQUEANDO LA CIRCULACION DE FLUIDOS A TRAVES DEL CITADO PASAJE DE CIRCULACION (12); Y DE UN SISTEMA DE CONTROL QUE RESPONDE A LA PRESION DE LOS FLUIDOS.
