地震勘探压缩数据的还原方法

Restorating Methods of Seismic Compression Data.

地震勘探数据通过压缩存储后 ,在需要使用原始采集数据时 ,必须将压缩了的数据释放出来恢复原状。文章论述了数据的无损还原的基本方法。数据还原模块可以在现有的设备上通过软件方式来实现 ,也可以使用一种或多种压缩技术的专用硬件设备来实现。实际情况表明 。

Afer the seismic data is compressed, if requiring the original seismic data, we must reduce the original data from compression data. This paper introduces the basic methods of undistorted reduction for the undistorted compression data. The data reduction module can be realized in field instrument by software method, or hardware equipment which synthesizes a or many compression data techniques. The actual appication showes the seismic data reduction method is as important as that of compression.
