引言可能,对地震工作者来说,声记录最有价值的部分莫过于合成地震记录道了。它与层速度测井有着近似正确的、适当的时间关系。速度测井本身,是对井中记录的声学资料的一个简单有用的显示。它图解地表示出时间与深度的关系以及一条地层的速度曲线。
Introduction Perhaps the most valuable part of sound recording for earthquake workers is synthetic seismograms. It has approximately the right, appropriate time relationship with velocity logging. The velocity log itself is a simple, useful indicator of the acoustic data recorded in the well. It graphically shows the relationship between time and depth and the velocity profile of a formation.
