Abstract
Un dispositivo de pesca autoblocante para ser empleado en herramientas de perforación de pozos petrolíferos, en donde dichas herramientas son preferentemente motores de fondo, mud motors, y lo similar. El dispositivo comprende un vástago substancialmente cilíndrico y hueco, y una pieza deslizante que presenta un orificio para el paso de dicho vástago, en donde el vástago comprende un extremo roscado para el acoplamiento de herramental, en tanto que en una porción distal a dicho extremo roscado, dicho vástago comprende una zona de reducción de diámetro, presentando la pieza deslizante un diámetro interno ligeramente superior al diámetro exterior de dicho vástago, en donde en una porción inferior de dicha pieza deslizante se presenta un ensanchamiento del diámetro interior, comprendiendo dicho ensanchamiento al menos una abertura de paso de liquido, estando dicho vástago y dicha pieza deslizante fijados mutuamente por un perno transversal. El dispositivo permite el paso de lodo a la zona motriz impidiendo la rotación del rotor en el caso de falla, logrando una alerta rápida al operador debido a la caída brusca de contra presión y evitando el aumento del efecto de las roturas.A self-locking fishing device to be used in oil well drilling tools, where said tools are preferably bottom motors, mud motors, and the like. The device comprises a substantially cylindrical and hollow rod, and a sliding piece having a hole for the passage of said rod, wherein the rod comprises a threaded end for tool coupling, while in a portion distal to said threaded end , said rod comprises a diameter reduction zone, the sliding piece having an internal diameter slightly larger than the outer diameter of said rod, wherein in a lower portion of said sliding piece there is a widening of the inner diameter, said broadening comprising at least a liquid passage opening, said rod and said sliding part being mutually fixed by a transverse bolt. The device allows sludge to enter the motor zone preventing the rotation of the rotor in the event of failure, achieving a quick alert to the operator due to the sudden fall of counter pressure and avoiding the increase of the effect of breakage.
