Biot理论应用于地震勘探的探索

本文根据弹性波的波动特性，探索引用Ｂｉｏｔ理论的基本观点描述实测地震记录，初步建立了套利用地震数据计算地层性参数的数学模型，并计算由震源引起的地震应力分布。地震应力信息反映地层沉积结构的某些特征，与地层的特性及所含流体有关，对研究储层参数有实际意义，说明Ｂｉｏｔ理论在地震勘探与开发中有应用的潜力。

Biot theory in application to seismic prospecting

This paper tries using the Biot theory to describe seismograms based on the characteristics of wave. For this end, a set of mathematical models is established for estimating elastic parameters of strata and seismic stress distributions caused by different sources on the basis of seismic data acquired. Having relations with the physical properties of strata and the fluid contained, the seismic stress information anyhow reflects certain features about the sedimentary structure of strata and is thus in essential to the parameter research for reservoirs. This shows the potential of the Biot theory in applieation to seismic prospecting and development.
