The analysis of seismic attenuation and time delay based on the Diffusivity-Viscosity wave equation
|
Abstract:
The attenuation of seismic wave and liquid forecast of the reservoir is a hot research problem in the field of geophysical prospecting of petroleum. Because of the difference of the category and the modality of the liquid in the bed, the character of the seismic wave will vary when propagating in the medium. It is the key of the liquid forecast to research and understand those mechanisms and characters, eventually, to test and display. However, such study is very complex, and it is in the period of groping research. The paper is based on the diffusivity-viscosity wave equation theory, emphasizes the research of seismic attenuation caused by the liquid-filled medium, simulates the alteration of the frequency energy and the time delays when seismic wave propagates in the liquid-filled medium. And eventually, the testing and interpretation method of those characters can provide the technique ideas and effective method for the liquid forecast in the reservoir with actual seismic data.
