   In this paper an attempt has been made to explain the theory of Neutron Logs. The basic relations between total porosity and the fundamental neutron characteristics are expressed in analytic way. This way of expression allows to define relationships for any rocks including also the chemically-pure limestone saturated with fresh water and drilled on condition that the diameter of the tool and the diameter of the borehole are identical. Such a model makes it possible to declare that total porosity equals neutron porosity, however, only for the above model. As the relations are rather complicated, it is convenient to use simpler relations of reciprocal type between neutron porosity and neutron characteristics. They are defined in a certain neutron porosity interval. All three simpler relationships enable a fast interpretation of neutron porosity
