Abstract:VSP is the new technology that geophysicists all over the world endeavor to study,Without the use of detector locking arm right now in China,the detectors can be sealed and fixed into the instrument used in neutron density logging in borehole,The energy of first arrival is characteriz.d by the inhomogeneity of the earth and the variation of lithology, As a consequence,the absorption coefficient,frequency spectrum and the reflectivity of each layer can be estimated from the frequency spectrum and energy of the first arrival.The reflectors can be positioned with the intersections of upward waves and first arrivats.The deep reflections detected in VSP are used to apprais,:the effectiveness of conventional sismie methods.
