【摘要】 在没有数字资料的情况下,如何充分利用旧的光点模拟地震纸剖面和胶片?如何重新对比解释,重新处理和储存这些资料(包括在上面作过手工解释的地震纸剖面)?如何解决硬拷贝的地震剖面只能阅读而不能进一步处理的困难?为了解决这些问题,提出了一个有效的途径,从而使老剖面、老胶片的重新处理和重新解释成为可能,即利用图形图象处理技术,首先对由扫描纸剖面得到的光栅图象上的地震波形进行预处理、细化、识别和提取,并转化为数字资料,若再重新格式化为标准的SEG-Y格式,则可以进一步用来处理和解释.通过对该技术应用于实际旧剖面所取得的结果的分析可以看到,在数字化的地震剖面上,原剖面的特征面貌得到有效恢复,可见,该技术用于旧地震剖面的重建是行之有效的.更多还原

【Abstract】 Without digital data, how to fully make use of the old optical analogue seismic sections and films and to renewedly constrast, reinterpret, especially to reprocess and restore them (including those on which have been manually interpreted), how to solve the problem that the hard copied seismic sections can only be read but not be further reprocessed, an effective approach has been put forward in this paper. Which makes it possible to reprocess and reinterpret old seismic sections and films. According to the graphical image processing technology, the seismic waveforms on the rasterized images scanned from paper seismic sections can be refined, identified and extracted and be converted into digital data, then be reformatted as the standard SEG-Y format, which can be used for being further processed and interpreted. Analyzing the results of applying this approach to old paper seismic sections, we realize that in the digitalized seismic sections their original characteristics can be effectively retrieved. Therefore this approach is feasible to reconstruct old paper seismic sections.更多还原
