Abstract: It is vulnerable to be influenced by the irregular borehole for shallow detection depth when the curves of density， P-wave velocity and shear velocity are used. In order to study the influence of the reservoir properties and the relationship between the elastic properties and the reservoir properties， the authors diagnosed and corrected the logging curves using rock physical model so that it can reflect the real formation information. The results show that the logging curves corrected with the rock physics model can significantly improve the logging data quality of reproduction. It can establish the correct relations between the well data and the seismic data and check the results of inversion seismic.
Key words: logging curve correction； rock physical model； equivalent medium model； Hashin-Shtrkman model； synthetic seismogram.
