Abstract

Буровое долото содержит множество кольцеобразных лопастей, соединенных с корпусом долота. Множество калибровочных площадок соединено с корпусом долота и задает внешний диаметр резания. Непрерывное в круговом направлении калибровочное кольцо соединено с корпусом долота и задает внутренний диаметр резания. Внутренняя режущая конструкция соединена с корпусом долота и имеет диаметр резания, по существу, равный внутреннему диаметру резания.
