Abstract

Un ensamblaje de pescante puede incluir una porción de cuerpo distal. La porción de cuerpo distal puede tener un eje central, una longitud a lo largo del eje central y una superficie exterior. Una superficie exterior de la porción del cuerpo distal puede definir, a lo largo de al menos una porción de la longitud, al menos una porción de acoplamiento de la sarta de perforación que tiene una primera distancia radial desde el eje central de la porción del cuerpo distal. La(s) porción(es) de acoplamiento de la sarta de perforación se puede configurar para inclinarse contra y deslizarse a lo largo de una superficie interna de una sarta de perforación. Al menos una porción empotrada puede estar espaciada hacia adentro desde dicha primera distancia radial desde el eje central.A davit assembly may include a distal body portion. The distal body portion may have a central axis, a length along the central axis, and an outer surface. An outer surface of the distal body portion may define, along at least a portion of the length, at least one engagement portion of the drill string having a first radial distance from the central axis of the body portion. distal. The engagement portion(s) of the drill string may be configured to tilt against and slide along an internal surface of a drill string. At least one recessed portion may be spaced inwardly from said first radial distance from the central axis.
