3D travel times reflection tomography used for depth conversion and uncertainty evaluation.

摘要: 3D travel time reflection tomography is performed on a marine data set (60km) in order to solve the depth conversion problem for low relief structure. About 270000 multi-offsets times are inverted constrain velocity and structure of subsurface. The best model agrees overall satisfactorily with well (0.5% accuracy). A perturbation method applied construct acceptable models (in terms kinematics). This technique enables us give uncertainties reservoir volumetrics.
