A DEVICE FOR REGISTRATION OF ROTATIONAL PARAMETERS DURING ASSEMBLY OF A PIPE STRING

摘要

Disclosed is a measuring sensor unit for registering one or more rotational parameters of forces that are exerted on a pipe string as it is being rotated into a well by a drilling machine. The measuring sensor unit has a body with a first end portion that is constructed to releasably engage with the end of a drilling machine drive shaft and a second end portion constructed to releasably engage with the end of a pipe string or with a tool that is integrated into a pipe string. Sensors are mounted on the measuring sensor unit and are in wireless communication with a signal transmitter. The sensors register one or more rotational parameters relevant for the rotation of the pipe string.
