English to Russian Tech/Engineering Geology Сейсморазведка

All the methods above are hardly applied to the practical data, and do not disclose how to use the downlink wave of the VSP data. Moreover, in all the methods above, a Q value obtained through inversion and a geologic velocity value hardly have correspondence, and it is impossible to estimate the reasonability of the Q value obtained through inversion. In addition, none of the methods above considers an excitation sub-wave difference caused by an excitation environment during collection, which hardly has applicability and generalization performance, and certainly will influence the stability of the quality factor Q.
