摘要
Through the forward modeling of visco-elastic wave equation,the authors discuss in this paper spectrum absorption characteristics of reservoir based on improved generalized S transform.When seismic waves pass through reservoir,high frequency energy attenuation is more severe than low frequency.So spectrum absorption characteristics show that low frequency energy is relatively augmented,and high frequency energy relatively diminished.The spectrum absorption characteristics can indicate the concentrated degree of petroleum in reservoir.The frequency spectrum analysis of model data and real seismic data near wells proves the effectiveness and feasibility of this method.
