Abstract

Соединение содержит охватываемый и охватывающий элементы, на концах которых на наружной и внутренней поверхностях, соответственно, выполнены упорные трапецеидальные резьбы с конусностью 1:16, углом наклона опорной грани профиля витка 2-4° к нормали осевой линии резьбы и углом наклона закладной грани профиля витка 9-11° к нормали осевой линии резьбы. Соединение выполнено с внутренним герметизирующим узлом, образуемым контактирующими между собой упорными торцевыми поверхностями, расположенными перпендикулярно к осевой линии резьбы. Длина упорного торца охватываемого элемента составляет 6,9-100,3 мм и находится в прямой зависимости от ширины зазора (Δ1) по закладной грани профиля витка резьб и в обратной зависимости от предела текучести материала охватываемого элемента. Достигается сохранение герметичности соединения при воздействии значительных разнонаправленных нагрузок, высокая износостойкость соединения, его улучшенные характеристики свинчиваемости, внутренняя равнопроходность колонны обсадных труб.The joint contains male and female elements, at the ends of which, on the outer and inner surfaces, respectively, there are persistent trapezoidal threads with a taper of 1:16, the angle of inclination of the bearing face of the coil profile is 2-4 ° to the normal of the axial line of the thread 9-11 ° to the centerline of the thread. The connection is made with an internal sealing assembly formed by contacting end abutment surfaces in contact with each other, located perpendicularly to the axial line of the thread. The length of the thrust end of the male element is 6.9-100.3 mm and is directly dependent on the width of the gap (Δ1) on the embedded face of the thread turn profile and inversely on the yield strength of the material of the male element. Achieved to maintain the integrity of the connection when exposed to significant multidirectional loads, high wear resistance of the connection, its improved screwing characteristics, internal equiprocession of the casing string.
