MPI‐based seismic wave field modeling in 3‐D viscoelastic random cavity medium

The results of seismic wave field modeling on the cross-section model of the crust (for Drobyshivske gas-condensate field example) were presented. Complicated cut of the crust, resulting geophysical study, represented as a reservoir model. When modeling, seismic wave field features of two-dimensional cross section were taken into account: longitudinal, transverse and exchange waves received on seismograms of longitudinal and transverse vibrations as a result of default distribution of velocities of longitudinal, transverse waves and the density in half-space medium.

Spatial Temporal Analysis

The article presents a space-time analysis of the seismic wave from a distributed career explosion. The method of direct measurement based on the dynamic model of the wave field is used to form an image of the seismic wave field in the field of quarry explosions. The efficiency of the proposed method is shown by the example of experimental seismic recording processing. The program "Nelumbo" is used to visualize the seismic field, which on the basis of experimental seismic records allows to form an image of the wave field in the space of the hemisphere, the center of which corresponds to the position of the seismometer (registration point). The algorithm of the program "Nelumbo" is based on the Huygens – Fresnel principle and Kirchhoff's theorem. The algorithm of the program allows to allocate from record of a seismic signal frames of a certain duration and to form the image of a wave field in space of a solid angle dimension π. This approach can be used as a tool to analyze the nature of the development of disturbances in the environment and the analysis of environmental risks in the production of blasting.
