SYSTEM AND METHOD FOR WELLBORE SURVEYING USING DIRECTIONAL GAMMA DETECTION |
| 摘要 |
A wellbore survey tool and methods for estimating a direction of highest gamma ray intensity of a gamma ray distribution are provided. The tool includes a body having a center axis. The body is configured to be placed within a wellbore. The tool further includes a plurality of gamma ray detectors within the body. Each detector of the plurality of gamma ray detectors has a direction of maximum gamma ray sensitivity with the direction having a non-zero component perpendicular to the center axis. The non-zero components of the plurality of gamma ray detectors are spaced circumferentially about the center axis. |
