There are considered various aspects of the numerical simulation of seismic waves connected with thin layer reservoirs. As a result we obtain both the horizontal and vertical displacement components, which are important for the analysis of seismic fields in the 3D seismic survey. In order to provide results nearer of the real experiment, in the mathematical formulation of the problem we use the deepened source of the type of the center of expansion. The solution of the problem, constructed in the spectral domain using the temporal Laplace and spatial Fourier-Bessel transforms, is studied in details to prove its applicability to the solution of direct and inverse dynamic seismic problems.

Special attention is done to analysis of the influence of the real part of the Laplace parameter on multi component seismograms corresponded to the horizontal and vertical components of the elastic field. Also, we discuss the computational aspects of the proposed scheme and carry out several analyses of the registered wave fields.

The results obtained demonstrated the potential of the method to help in the process of characterization of thin reservoirs in comparison with other methods: Isto pode estar relacionado a dois fatos. Consideremos um meio composto por n camadas estratificadas: Em virtude disto, as Eqs. Repetindo este procedimento camada por camada, calculamos os valores s ij 0.

Agora, utilizando as Eqs. O potencial da onda longitudinal plana incidente pode ser representado da seguinte forma. A seguir, descrevemos as principais modelagens realizadas. As singularidades do espetro observado apresentam mais explicitamente a descontinuidade da estrutura. Na Figura 3 ba escala ampliada do eixo mostra os valores do espectro.

A Figura 4 comprova a similaridade entre a estrutura dosespectros 2D obtidos em diferentes modelos. O desmembramento das transformadas permitiu criar um algoritmo mais efetivo. Este sismograma multicomponente, embora elementar, mostra a possibilidade de identificar os diferentes tipos de componentes das ondas. Na componente horizontal nitidamente revelam-se todos os tipos de ondas.

Isto pode ser justificado pelo uso de um tipo diferente de fonte. Tal procedimento possui vantagens relevantes: University Science Books, Sausalito, California. A method for calculation of stationary elastic oscillations in stratified media.
