LWD sonic frame
Sonic logging is a logging method to study the geological profile of drilling and judge the cementing quality by using the different acoustic characteristics such as the changes of velocity, amplitude and frequency when acoustic waves propagate in different rocks.

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.
