Abstract

Изобретение относится к системе крепления расширяемой трубы к стенке ствола буровой скважины. Система содержит опорный элемент, первый конец которого закреплен относительно внешней поверхности трубы, а второй конец имеет наклонную поверхность. Первый конец анкера закреплен на внешней поверхности трубы, а второй его конец направлен в сторону опорного элемента и является подвижным относительно внешней поверхности трубы. Указанный опорный элемент имеет наклонную поверхность с наклоном в сторону анкера. Расширение части расширяемой трубы между первым концом опорного элемента и первым концом анкера приводит к уменьшению осевой длины устройства, причем разность по длине является достаточной для того, чтобы в результате взаимодействия с наклонной поверхностью второй конец анкера сместился радиально в сторону и вошел в зацепление со стенкой ствола скважины.
