彩色地震剖面显示是地震剖面显示技术中较为先进的一种显示方式.它具有常规黑白显示剖面所无法比拟的优点.尤其是在一些特殊处理显示的剖面(诸如三瞬剖面、虚速度测井剖面以及烃类显示剖面)中,这些剖面给人以清晰直观和一目了然的感觉.但是,目前彩色剖面在国内尚未得到普遍地应用,其原因之一是由于彩色显示处理要求计算机具有大的内存容量和高速运算等方面的性能,所以一般都是在大中型计算机上处理.而小型计算机由于内存容量和运算速度等面存在着不足,所以难以运行象现今国内所使用的UNIRAS这样庞大的系统.笔者在研究了UNIRAS系统的实现原理后,另辟蹊径,在只有32k内存容量又无虚拟存贮管理系统的TEMPUSⅡ小型计算机上,采用光栅处理技术,实现了地震剖面彩色显示,并取得了令人满意的结果.
The color seismic profile display is one of the more advanced display methods in seismic profile display technology, which has the unmatched advantages of the conventional black-and-white display profile, especially in some specially processed profiles (such as the three-moment profile, the virtual velocity profile And hydrocarbon display profiles), these profiles give a clear, intuitive and clear impression.However, one of the reasons why color profiles are currently not widely used in China is that the color display processing requires that the computer have a large memory capacity and High-speed computing and other aspects of the performance, it is generally handled in large and medium-sized computers.Microcomputer due to the memory capacity and computing speed of the surface there is a shortage, it is difficult to run like today’s domestic UNIRAS such a huge system. After researching the implementation principle of UNIRAS system, this paper uses the grating processing technology to realize the color display of seismic profile on the TEMPUS II small computer with only 32k memory capacity and no virtual storage management system, and achieved satisfactory results.
