摘要： Systems and methods for well-drilling operations involving magnetic ranging with a rotating magnetic source are provided. In one embodiment, a system for determining a relative location of a magnetic source includes a three-axis magnetometer and data processing circuitry. The three-axis magnetometer may measure a time-dependent magnetic field caused by a magnetic source rotating about an axis, which may include two transverse components transverse to the axis and the data processing circuitry may determine a transverse angle of rotation of the measurements such that one of the two transverse components is ±π/2 radians out-of-phase with the other when the measurements are transformed by the transverse angle of rotation. The data processing circuitry may determine a spatial relationship between the magnetic source and the three-axis magnetometer based at least in part on the transverse angle of rotation.

摘要： To determine effect on a magnetic field caused by a lining structure in a wellbore, an array may be deployed into the wellbore lined with the lining structure. The array comprises a plurality of sensors including sensor A configured to operate as a transmitter, sensor B configured to operate as either a transmitter or a receiver, and sensor C configured to operate as a receiver. The array measures magnetic fields using sensor B as a receiver and sensor C in response to activation of sensor B as a transmitter and sensor A. A plurality of lining structure correction factors can be calculated based on the measured magnetic fields, based on the reciprocity of the sensors.

摘要： A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.

摘要： A method is provided for conducting measurements of a borehole while drilling the borehole in a geological formation. First, a rotatable drilling assembly is provided that has, at a forward end, a drill bit and a borehole measurement tool connected rearward of the drill bit. The measurement tool includes at least one caliper arm extendible outward from the measurement tool. The method involves drilling the borehole by operating the rotatable drilling assembly. While drilling, the wall of the borehole is contacted with at least one extendable caliper arm of the borehole measurement tool and the extension of the caliper arm contacting the borehole wall is measured, thereby determining a distance between the measurement tool and the borehole wall. During rotation of the drilling assembly, contact is maintained between the caliper arm and the borehole wall and the measuring step is repeated at multiple positions of the drilling assembly.
