摘要

Method for quantificau00c7u00e7o and mitigau00c7ao to avo vertical induced by inclinau00c7ao. This patent delineja methods to quantify and mitigate effects induced by AVO vertical inclination in the detection of seismic fracture analysis by using AVO azimuthing account accurately, the correction of divergence and vertical dependence of the reflection angle.Are provided with solutions for three cases: (1) the isotropic tilted reservoirs; (2) anisotropic reservoirs with fractures aligned in the arbitrary direction; and (3) anisotropic reservoirs where vertical fractures are aligned perpendicular to the direction of inclination.
