Bending correction for deep reading azimuthal propagation resistivity |
摘要 |
<p>An apparatus and method for estimating a parameter of interest in a borehole penetrating an earth formation using a receiver and a transmitter, both disposed on a carrier, with aligned magnetic moments to correct for bending of carrier during borehole investigations. The apparatus may include a transmitter with at least two substantially perpendicular coils and a receiver with at least one coil oriented with at least one or the transmitter coils. The method may include aligning the magnetic moment of the transmitter and the magnetic moment of the receiver prior to estimating the parameter of interest. The method may include supplying a constant electric current to one of the transmitter coils while supplying a varying electric current to another of the transmitter coils. The method may include estimating a direction of bending or angle of bending of the carrier.</p> |
