Abstract

La invención se refiere a equipos de petróleo y gas y se puede aplicar para conexiones roscadas para tuberías de revestimiento usadas para la construcción de pozos verticales, direccionales y horizontales. La conexión consiste en elementos macho y hembra, cuyos extremos, tanto en el exterior como en el interior, se fabrican correspondientemente con roscas trapezoidales cónicas, superficies de sellado, de transición y de hombro. Las crestas y raíces del perfil de vuelta de la rosca son paralelas a la línea axial de la rosca. Las superficies adicionales se producen en forma de superficie cónica en el elemento hembra y de superficie cónica o superficie esférica convexa en el elemento macho. La transición de las superficies de sellado a las superficies adicionales se produce en forma de superficie esférica cóncava en el elemento macho y de superficie esférica convexa en el elemento hembra. Se logra una alta estanqueidad de la conexión bajo suficientes cargas mecánicas mediante características mejoradas de la formación de la conexión, prevención de atascos de la conexión en la etapa inicial de formación, y ausencia de daños (excoriación) de las superficies de sellado.
