Abstract

1. Dispositivo de empalme para equipo de perforación, que comprende un cuerpo alargado según un eje vertical, provisto interiormente de un taladro axial y que forma exteriormente porciones cilíndricas extremas superior e inferior provistas en sus extremos libres de medios de enroscadura, para la inserción del dispositivo de empalme en un equipo de perforación, así como una porción cilíndrica intermedia engrosada, de diámetro exterior mayor que el diámetro exterior de la porción superior, que presenta así una cara superior de empalme con la porción superior, caracterizado porque dicha porción intermedia está provista de al menos tres huecos cada uno de los cuales corta dicha cara superior y alcanza dicho taladro axial, repartidos circunferencialmente a intervalos regulares unos de otros, y porque, en cada uno de estos huecos se inserta una pieza postiza, provista de un paso interno dirigido de abajo hacia arriba, que se abre por su parte inferior en dicho taladro y que desemboca por su partesuperior por una dusa situada en un diámetro comprendido entre el diámetro exterior de dicha porción intermedia y el diamétro exterior de dicha porción superior. 2. Dispositivo según la reivindicación 1, caracterizado porque dicha cara superior está provista de recarga de un material duro. 3. Dispositivo según la reivindicación 1, caracterizado porque dicha cara superior de empalme de dicha porción intermedia a dicha porción superior presenta una forma general troncocónica y porque cada hueco forma una brecha comprendida entre dos bordes dirigidos hacia e inteiror del racor de tren de perforación. 4. Dispositivo según la reivindicación 3, caracterizado porque dicho cuerpo lleva recargas de un material duro, por una parte, sobre lo que queda del contorno exterior de dicha cara superior después de la ejecución de los huecos y, por otra parte, sobre aquel de dichos bordes que, según el sentido de rotación del equipo de perforación constituye un borde ataque. 5. Dispositivo según la reivindicación 1, caracterizado porque la superficie cilíndrica de dicha porción intermedia está provista de ranuras helicoidales. 6. Dispositivo según la reivindicación 1, caracterizado porque cada pieza postiza es una pieza de acero tratado amovible y mantenida in situ por al menos un pasador que se inserta en agujeros alineados de la pieza postiza y de la porción intermedia y retenido a su vez por un tornillo. 7. Dispositivo según la reivindicación 1, caracterizado porque cada dusa es un elemento postizo intercambiable, de carburo de tungsteno, retenido por un anillo elástico. 8. Dispositivo según la reivindicación 1, caracterizado porque cada pieza postiza comprende una sección cilíndrica que se introduce en una parte correspondiente del hueco cerca del taladro axial y porque se inserta una junta hermética alrededor de esta sección cilíndrica. 9. Dispositivo de empalme para equipo de perforación.
