CDP公司用康派克75系统进行数字处理(见前文)。系统是积木化的,由35个以上的主程序和100多个子程序组成。既有时间域也有频率域的处理程序。可随意选用。控制参数十分灵活,无论在时间上还是在空间上都是可变的。在各个程序内有可选参数。许多情况下可选参数能够略去,同时程序会自动地调整到标准处理程序。在运算的任何阶段都可以调整控制参数并绘制出任何过程的结果,用于考察其进展。一切解编程序都输出标准化的顺序记录道而无记录格式上的差错。所有的中间处理都要求其输入是顺序记录格式。待处理的记录格式是这样构成的,前面是磁带记录头,紧接其后是每个需处理的地震道数据。记录头上记有诸如记录长度、取样速度及其在处理中会用到的与记录有关的参数。一旦加上了这些资料,以后就无需再输入它们了。例如正常时差用的道距一经输入,就保存在记录头内待用。需要时,正常时差程序就可使用这种资料。普通的运算,如线性记录道比例、记录前端的削减等,可在顺序处理中的任何阶段实现。在顺序处理中不必增加新的步骤,因为比例和削减可和任何其它处理同时实现。一张记录内有多少道可以不同,可处理的数目最多为每张记录99道。
CDP uses Digital Pack 75 systems for digital processing (see above). System is building blocks, composed of more than 35 main programs and more than 100 subprograms. Both the time domain and frequency domain handler. Free to choose. Control parameters are very flexible, both in time and in space are variable. There are optional parameters in each program. In many cases, optional parameters can be omitted, and the program automatically adjusts to the standard handler. The control parameters can be adjusted at any stage of the operation and the results of any process can be plotted to examine their progress. All unpackers output a standardized sequence of tracks without errors in the recording format. All intermediate processing requires that its input be a sequential record format. The record format to be processed is constructed in such a way that the front is the tape recording head, followed by each of the seismic trace data to be processed. Recording head, such as record length, sampling speed and its processing will be used in the recording-related parameters. Once you have added this information, you do not need to enter them later. For example, when the track for normal time difference is input, it is stored in the recording head for use. This information can be used by normal time difference procedures when needed. Ordinary operations, such as linear track ratio, recording front-end reduction, etc., can be implemented at any stage in sequential processing. There is no need to add new steps in the sequential processing, as scaling and reduction can be done simultaneously with any other processing. The number of tracks in a record can vary from up to 99 tracks per record.
