Abstract

Блок для применения в подземном бурении содержит скважинный зонд, поддерживаемый центратором. Центратор содержит трубчатый элемент, который проходит вокруг скважинного зонда. Стенка центратора снабжена канавками для обеспечения точек внутреннего контакта, которые поддерживают скважинный зонд, и точек внешнего контакта, которые упираются в стенку ствола секции бурильной колонны. Скважинный зонд может быть поддержан, по существу, по всей его длине.
