Research on Constrained Sedimentary Facies Reservoir by Well-seismic Inversion

Abstract

The combination of well and seismic is a geophysical method to describe sedimentary microfacies. Seismic inversion is mainly used to predict the continuity of cross-well sand bodies, the geometric shape of sand bodies and the boundary of cross-well sand bodies, to make up for the lack of cross-well information. Combining logging information, reasonable combination and prediction are made according to certain sedimentary model, and the distribution of different sedimentary microfacies sand bodies is described.
