摘要： Various implementations described herein refer to an apparatus having an instrument cluster with accelerometers and gyroscopic sensors. The apparatus may include a controller that communicates with the instrument cluster, receives measurement data from the accelerometers and the gyroscopic sensors, and acquires a computed tool orientation of a drilling tool based on the measurement data from the accelerometers and the gyroscopic sensors. The controller may generate tool steering commands for the drilling tool based on a difference between a planned tool orientation and the computed tool orientation.

摘要： Systems and methods are provided for producing a continuous survey of a previously drilled portion of a wellbore. The method includes receiving a plurality of stationary survey measurements taken at a corresponding plurality of locations along the portion of the wellbore. The method further includes receiving at least one continuous survey including a plurality of continuous survey measurements taken between a pair of stationary survey measurements of the plurality of stationary survey measurements. The method further includes combining the plurality of stationary survey measurements and the plurality of continuous survey measurements to produce the continuous survey of the portion of the wellbore.

摘要： A method and an apparatus are provided for determining an orientation of a tool with respect to a reference direction. At least one first signal is indicative of an orientation of a directional reference system with respect to the reference direction. The directional reference system is positioned spaced from the tool. At least one second signal is indicative of a relative orientation of the tool with respect to the directional reference system. The orientation of the tool at the first position is determined in response at least in part to the at least one first signal and the at least one second signal.

摘要： Various implementations described herein are directed to a method for surveying a wellbore. A statistical estimation process that combines magnetic survey measurement data and gyroscopic survey measurement data to form error estimates in a magnetic survey system is applied. The error estimates are used to correct magnetic survey data provided by the magnetic survey system. Magnetic only survey data is used when convergence of the error estimates has occurred. Information that facilitates drilling the wellbore is provided.

摘要： A method and an apparatus are provided for determining an orientation of a tool with respect to a reference direction. The tool is configured to be moved along a wellbore and to generate information usable to determine an orientation of the tool. At least one first signal is indicative of an orientation of a directional reference system with respect to the reference direction. Information regarding a relative orientation of the tool with respect to the directional reference system is used to determine the orientation of the tool with respect to the reference direction in response at least in part to the at least one first signal.
