MULTIPOLE ANTENNAE FOR LOGGING-WHILE-DRILLING RESISTIVITY MEASUREMENTS |
| 摘要 |
<p>A multipole antenna for conducting logging-while-drilling (LWD), includes a wire for one of producing and receiving an electromagnetic field, the wire having at least one winding for providing a magnetic moment in a first portion of the antenna that is opposite to the magnetic moment of a second portion of the antenna. A method for constructing the multipole antenna is provided. A LWD tool making use of the antenna is also provided</p> |
