Abstract

A retractable top drive for use with a drilling rig and process for operating a drilling rig. The retractable top drive comprises a dolly having a pair of mast rails in translatable relation to a mast, such as sliding. A yoke pivotally connects a torque tube to the dolly and the top drive is connected to the torque tube, so that a substantial portion of the top drive is positioned lower than a substantial portion of the dolly. An extendable actuator is connected between the dolly and the yoke to translate the top drive to / from the dolly. Torque is transferred from the top drive through the torque tube, yoke and dolly into the mast of the drill rig.

Description

[0001] continue statement [0002] This application claims priority to US Provisional Application No. 62 / 330,028, filed April 29, 2016. technical field [0003] The present disclosure relates to a drilling rig and system for moving drill pipe and drill collars into and out of a subterranean wellbore. In particular, the present invention relates to a retractable top drive (RTD) for use on a drilling rig, which is designed to significantly reduce the trip time of the drill string. Specifically, the present design is configured for use with a second crane that is translatably mounted to the same mast as the telescoping top drive. Background technique [0004] In the exploration for oil, gas and geothermal energy, drilling operations are used to form boreholes or wells in the ground. Drilling rigs used for subsurface exploration must be transported to the location where drilling activities are to begin. These locations are often located in remote, rugged terrain. Transportin...
