Abstract

The present invention relates to a method for automated handling of drilling tools on a drilling and workover rig, comprising the following steps: S11, a drilling control system controls a traveling hoist system to lift a target drilling tool in a wellbore to a target height, and the drilling control system controls a slip lifting and lowering device at a wellhead position to clamp the target drilling tool; S12, the drilling control system controls a roughneck on a drilling platform to disconnect the drilling tool and the target drilling tool in the wellbore; S13, the drilling control system controls a sub-deck manipulator below the second-deck platform of the derrick and a drilling platform manipulator on the drilling platform to lift the target drilling tool to a position away from the wellhead and transfer the target drilling tool to a handover position; S14, the drilling control system controls an on-deck manipulator above the second-deck platform of the derrick and a drilling platform manipulator to transfer the target drilling tool from the handover position to a storage position within the finger beam of the second-deck platform of the derrick for storage. The method has the beneficial effect of improving safety and operational efficiency.
