利用水、汽油和甘油等常见材料制作三维液体模型,可供地震勘探方法试验。模型Ⅰ是一个三维透镜体,所得到的光点反射记录,证实了“亮点”具有振幅增强,极性反转等特征。模型Ⅱ是一个礁块构造,在几条测线上观测到的记录,清楚地显示了模型的轮廓。模型Ⅲ是一个简单三维模型,应用十字观测法进行观测的数据,反演了模型的宽度和厚度。上述实验表明,方法是可行的,效果是良好的。 Produce 3D liquid models from common materials such as water, gasoline and glycerin for seismic exploration method testing. Model I is a three-dimensional lens body, and the obtained spot reflection record confirms that the “bright spot” has the characteristics of amplitude enhancement and polarity reversal. Model II is a reef block structure, observed on several lines recorded, clearly shows the outline of the model. Model III is a simple three-dimensional model, the data observed using the cross observation, the inversion of the width and thickness of the model. The above experiment shows that the method is feasible and the effect is good.
