| description | The present invention provides a method for obtaining a conversion relationship between dynamic and static elastic parameters. The method comprises: Step S1, acquiring horizontal cores at different depths of the destination formation; Step S2, measuring the 5 dynamic elastic parameters of the horizontal core under different pressures; Step S3, measuring the static elastic parameters of the horizontal core under different pressures; Step S4, measuring the clay content of the horizontal core; Step S5, , establishing a function relationship of the ratio between the dynamic and static elastic parameters with the formation pressure and clay content; and completing the conversion between the dynamic 10 and static elastic parameters. The technical solution provided by the present invention takes full account of the influence of the formation stress and the clay content on the conversion rule of dynamic and static elastic parameters and is of great significance for improving the logging evaluation accuracy of rock mechanical parameters. |
