The formation density logging is based on the Compton scattering effect of gamma rays and matter in the formation. The scattering effect depends on the neuclear characteristics and the bulk density of the matter. The neutron log measures the as yet uncaptured thermal neutron density which directly relates to the hydrogen content of the formation. According to the measuring equations of the two logs, this paper demonstrated theoretically that density log is not independent of neutron log.The two logs do relate for most sedimentary rocks and minerals encountered in hydrocarbon bearing basins. The good correlation between density log and neutron log results in broad applications in formation evaluation, such as determination of porosity, identification of lithology, especially in identification of natural gas formation and of contact of oil and gas.The field example showed that the excellent correlation between the two logs in all formations including oil,gas,and water layers.The application of the correlativity much improved the determination of the contact of oil and gas.
