DETERMINING FORMATION PARAMETERS USING ELECTROMAGNETIC COUPLING COMPONENTS |
摘要 |
A method to determine one or more parameters of a formation traversed by a borehole, at least a portion of the formation having substantially parallel boundaries, the method comprising disposing a tool in the borehole, wherein the tool includes a transmitter having a dipole moment at an angle TT with respect to a longitudinal axis of the tool and a receiver having a dipole moment at an angle TR with respect to the longitudinal axis of the tool, the transmitter and receiver comprising a transmitter-receiver pair; transmitting an electromagnetic signal while rotating the tool; receiving the electromagnetic signal to produce a measured signal from the transmitter-receiver pair; and determining the one or more formation parameters for the portion of the formation having substantially parallel boundaries based on the measured signal from the transmitter-receiver pair. A tool disposed in a borehole penetrating a formation, at least a portion of the formation having substantially parallel boundaries, the tool comprising a single transmitter having a transmitter dipole moment at an angle TT with respect to a longitudinal axis of the tool; a single receiver having a receiver dipole moment at an angle TR with respect to the longitudinal axis of the tool; and a rotational position indicator. |
