Abstract
Techniques for implementing antenna configurations with substantially co-located axes are disclosed. A method for constructing co-located antennas includes winding a first antenna on a support, the first antenna having a first magnetic dipole in a first orientation; and winding a second antenna on the support through a first set of openings in the support, the second antenna having a second magnetic dipole in a second orientation, wherein the first orientation is different from the second orientation, and wherein a center of the first magnetic dipole substantially co-locates with a center of the second magnetic dipole.
Claims11
An antenna assembly formed on a tool body diposed in a well, comprising a plurality of antennas formed on the tool body the plurality of antennas having centers of their magnetic dipoles substantially co-located, and wherein at least one of the plurality of antennas is formed by winding a wire through an opening in the tool body.
A logging tool, comprising:
- a tool body;
- a first antenna assembly formed on the tool body;
- and
- a second antenna assembly formed on the tool body and spaced apart from the first antenna assembly along a longitudinal axis of the logging tool, wherein the first antenna assembly comprises a plurality of antennas having centers of their magnetic dipoles substantially co-located, and wherein at least one of the plurality of antennas is formed on the tool body by winding a wire through openings in the tool body.
