摘要
A computer-implemented method for obtaining the characteristics of the elastic properties of underground geological formations for various conditions of its fluid saturation is described. This method involves estimating density and bulk compression moduli for fluids and surrounding rocks present in infiltration zones around the wellbore and outside the affected area in order to record a set of logging curves for densities and volumetric compression moduli of fluids and surrounding rocks present in the infiltration zones and outside the infiltration zone from the depth of penetration; Record a set of curves of compaction of oil and gas reservoirs in each wellbore; solving a set of petrophysical equations for rock and fluid volumes based on a recorded set of logging curves and oil and gas reservoir compaction curves for calculating lithology, porosity and hydrocarbon saturation in order to build computer models for estimating the saturation of hydrocarbon filling rocks near the wellbore; and using the obtained estimates of the densities and moduli of volumetric compression of fluids and filling rocks near the wellbore, compaction curves of oil and gas reservoirs and calculated lithology, porosity and hydrocarbon saturation of rocks near the wellbore in order to obtain characteristics of the elastic properties of subterranean formations for different fluid saturation conditions.
