Methods for real time control of a mobile rig

摘要

A completion system and method adapted for use in wells having long lateral boreholes includes a mast assembly, a pipe handling mechanism, a pipe arm, a pipe tub, a pump/pit combination skid, a rig carrier, and a control system. The control system can be used to automate operations of the completion system to facilitate rapid and safe make-up and breaking of tubular connections.

1. A method for real time control of a mobile rig, the method comprising the steps of:
providing a mobile rig in association with a wellbore, wherein the mobile rig comprises:
a mast assembly extending vertically above the wellbore;a drive unit configured to move along the mast assembly and to engage tubular segments;a pipe handling system comprising at least one vessel for containing tubular segments and a pipe moving arm configured to engage and transport tubular segments to and from the drive unit, anda control system comprising a movable control room configured for remotely controlling and automating operations of the pipe handling system, the mast assembly, the drive unit, or combinations thereof, wherein the control system is programmed to operate the entire pipe handling system in a coordinated manner for real time operation; aligning the mast assembly of the mobile rig with the wellbore using a sensor on the mobile rig; transferring a tubular segment from the at least one vessel to the pipe moving arm; using the control system to engage the tubular segment with the pipe moving arm; using the control system to move the pipe moving arm from a first position for transferring tubular segments between the pipe moving arm and the at least one vessel to a second position for transferring tubular segments between the pipe moving arm and the drive unit; aligning the tubular segment with the mast assembly; using the control system to move the drive unit along the mast assembly to engage the tubular segment; using the control system to disengage the pipe moving arm from the tubular segment and move the pipe moving arm to the first position; and using the control system to move the drive unit along the mast assembly to engage the tubular segment with a tubular string associated with the wellbore.
