DRILLING CONTROL TRANSFER SYSTEMS

摘要

Disclosed is a system for regulating and controlling well drilling operations where the control of the operations is interchangeable between a location at the rig for manual control and remote location away from the rig for remote control. The manual and remote control functions are continually compared and regulated to maintain a parity therebetween, thereby permitting "bumpless" transfer between the control at one location to the control at the other location.
