Control procedure for well drilling operations

Patent:

Abstract

A control procedure of rotary drilling operations is proposed. It uses the Drill off test. The drill-off test permits to determine the rock drill speed variation as a function of the wright applied on the top of the pipe. We can deduce from that a rock drill wear parameter. The method permits to prevent a rupture and its grave economic consequences.
