Directional Antennas For Electromagnetic Mapping In a Borehole |
| 摘要 |
A bottom hole assembly used for a field operation is disclosed herein. The bottom hole assembly can include at least one directional antenna disposed on an outer surface of a first tubing pipe of a tubing string, where the at least one directional antenna receives a first electric current from at least one power source, where the first electric current generates a first magnetic field that radiates from the at least one directional antenna into a formation. The bottom hole assembly can also include at least one receiver disposed on a second tubing pipe of the tubing string, where the at least one receiver receives the first magnetic field returning from the formation. |

1. A bottom hole assembly used for a field operation, comprising:
at least one directional antenna disposed on an outer surface of a first tubing pipe of a tubing string, wherein the at least one directional antenna receives a first electric current from at least one power source, wherein the first electric current generates a first magnetic field that radiates from the at least one directional antenna into a formation in the field; and at least one receiver disposed on a second tubing pipe of the tubing string, wherein the at least one receiver receives the first magnetic field returning from the formation. |
