地震声学 [dì zhèn shēng xué]
seismoacoustics
- 选择相应特征的典型浅层气地震记录，进行了声学成因解释，讨论了大型塌陷坑的浅层气成因、海水层中声学反射与浅层气体的成因关系以及浅层气地震特征的气体浓度指示作用。
Selecting typical seismic record with related features in the area, we explained their acoustic causes and discussed (1)the origin relation between shallow gas and acoustic reflection in seawater column, (2)shallow gas causing the giant sunken pit, and (3)concentration indications of the shallow gas seismic features. - 该区的浅层气地震特征按空间位置分为3大类：(1)地层中的特征：声学空白、声学幕、声学扰动、不规则强反射顶界面、两侧相位下拉；(2)海底面的特征：海底麻坑、大型塌陷坑；(3)海水层中的特征：声学羽流、云状扰动、点划线反射。
According to their space position, the seismic features of shallow gas in this region can be divided into three groups: (1) features in the stratum: acoustic blanket, acoustic curtains, acoustic turbidity, irregular strong top reflection boundary, and phase pull-down in both flanks; (2)features of the seabed: seabed pockmark and giant sunken pit; (3)features in the seawater column: acoustic plumes, cloudy turbidity and point-line-type reflection. - 地震正演方法包含两个关键步骤，一是利用弹性波动方程计算含缝洞介质的有效弹性参数，另一步骤是根据有效弹性参数构成的等效地质模型，用单程声学波动方程进行波场延拓。
The seismic modeling algorithm includes in two key steps in which one is for calculating effective elastic parameters in a fractured and caved media by using elastic wave equation, the other is for wave extrapolating by using acoustic one-way wave equation based on an equivalent geology model consisting of those effective parameters.
