摘要： Systems, methods, and devices for two-way communication with a downhole tool string are provided. In one example, a method may include placing a downhole tool string into a pressure riser of a well while at least one component of the downhole tool string is not activated. Thereafter, a wireless control signal may be issued through the pressure riser to the downhole tool to cause the downhole tool string to activate the component. The wireless control signal may involve an acoustic signal, an optical signal, and/or an electromagnetic signal such as electrical dipole coupling or magnetic dipole coupling.

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.

摘要： A high vertical resolution antenna design is provided for use in an NMR measurement apparatus. Multiple coils are situated along the length of a magnet. A primary coil is energized to cause an oscillating magnetic field in a portion of earth formation surrounding a borehole. A secondary coil having smaller dimensions than the primary coil is operated to receive spin echoes from a depth of investigation associated with the secondary coil. A distance sufficient to minimize electrical coupling separates the coils. The separation distance can be reduced by selecting a secondary coil with orthogonal polarization to the primary coil. Alternatively, a cross coil configuration can be implemented where the orthogonal secondary coil at least partially overlaps the primary coil, thereby reducing the overall length necessary for the polarizing magnet.
