Applied seismic forward modeling(part Ⅰ): Accurate interpretation of the Donghe sandstone pinchout by post-stack seismic forward modeling;

A finite-difference seismic modeling method based on triangular grids is presented.

A seismic modeling system includes four functions, that is, to input the model and arrayparameters such as source and receive parameters, compute the finite element seismic modeling, modify the previous model parameters and recalculate the seismic modeling.

The correlation of biolimestone thickness and seismic reflecting amplitude and frequency were clarified by establishing seismic forward model for different enclosing rock combinations and different biolimestone thickness.

The study taking the data volume acquired from model and seismic forward simulation as object can push development and bringing forth new ideas of seismic approaches.
