advantages:

1:It is used for exploring the dry borehole.

2:The method that compensated density can divide the strata, determine.

3:the porosity of rock and density of volume. Naturalγis applied to identify lithology, locate the strata, estimate the sludge

4:content, tell the rock strata from the shale one. Evaluate the radiate minerals that have a content of potash, anhydrite or U

5 find out the non-radiate minerals like salty rock, non-water gypsum and so on.
