5 радиус изгиба бурильной трубы по маршруту скважины
3.2.11 радиус изгиба бурильной трубы по маршруту скважины (drill pipe bore path bend radius) R: Расчетный предел радиуса изгиба углеродистой стальной трубы в колонне труб в процессе операции бурения, определяемый формулой:
где R - радиус изгиба, м;
Е - модуль упругости материала трубы, МПа;
D1 - наружный диаметр трубы, мм;
U - заданное напряжение растяжения материала трубы, МПа.
