Gamma Module For LWD

The downhole probe is converted into electrical pulse signals by the natural gamma rays of the gamma detector formation. After processing, the count rate of the gamma rays is obtained, which is transmitted to the ground through the mud pulse transmission system of MWD, and the real-time gamma rays are obtained after processing. Horse curve. At the same time, the gamma count rate is sent to the memory of the gamma probe for storage. After the probe is taken out from the bottom of the well, the stored data is processed to obtain the replayed gamma curve.

Gamma module for LWD

The Gamma ray log measures the natural gamma radiation produced by the disintegration, or decay, of radioactive nuclei in the formation.

 

Gamma ray logs are helpful for quantifying shaliness, well-to-well correlation, depth correlation between open- and cased-hole logs, and for correlation between logging runs.
