在用地震和地质雷达(GPR)数据作浅层勘探的应用中,研制了一个叫做GeoSim/GeoEyes的交互图形软件系统,用于模拟在实际地质介质中的声波和电磁波的传播,以及在仿真数据上对层析成像方案作评价。GeoSim/GeoEyes仿真环境是在工作站上XWindows/Motif交互图形系统下开发的。GeoSim/GeoEyes系统由4个主要次级处理过程组成,受顶层主功能控制:(1)地质模型和参数产生;(2)信号仿真;(3)层析图象预览和产生;(4)图象显示和分析。尽管GeoSim/GeoEyes的开发主要是为了在实际数据采集之前用仿真信号评价层析成像方案,但该系统也可以处理野外采集的实际地震和电磁场数据,所以仿真成像和从实际数据产生的图象相比较,将允许对模型的合法性进行评价以致提高模型参数的精度。
In applications using shallow seismic exploration and geologic radar (GPR) data, an interactive graphics software system called GeoSim / GeoEyes was developed to simulate the propagation of acoustic and electromagnetic waves in real geologic media, as well as to simulate data On the tomographic imaging program for evaluation. GeoSim / GeoEyes simulation environment is developed on the workstation under the XWindows / Motif interactive graphics system. The GeoSim / GeoEyes system consists of four main sub-processes controlled by the top-level main functions: (1) geological models and parameters generation; (2) signal simulation; (3) tomographic preview and generation; Like display and analysis. Although GeoSim / GeoEyes was developed primarily to evaluate tomographic imaging with simulated signals prior to actual data acquisition, the system can also process actual seismic and electromagnetic field data collected in the field, so simulation imaging and image generation from actual data The comparison will allow to evaluate the validity of the model so as to improve the accuracy of the model parameters.
