Description：
|
The Litho-Density tool uses a gamma source (1.5Ci, Cs137) and two detectors of different spacing to contact the sidewall directly. Based on Photoelectric Effect and Compton Effect, corresponding energy windows are set up, recording the gamma ray of various windows, and measuring the lithology and density of formation.
