利用正常时差和平均速度之间的关系确定地震速度。经典速度分析的准确度受到限制,并且不能用一般的方法增加准确度。为了减少速度确定过程中固有误差的限制,运用了统计方法。为了这个目的,必须增加单速度分析的统计资料或者是必须分析大量独立的计算速度的数据。增加一个单速度分析的统计资料用于MVD(偏移速度确定)过程中(萨特莱格尔,1973年国际勘探地球物理学家协会会议)。MVD速度沿测线表现出一致性,并与
Seismic velocity is determined using the relationship between normal time difference and average velocity. The accuracy of classical velocity analysis is limited and the accuracy can not be increased in the usual way. To reduce the limitation of inherent error in the speed determination process, a statistical approach was used. For this purpose, statistics for a single velocity analysis must be added or data must be analyzed for a large number of independent calculations. Add statistics for a single velocity analysis for use in MVD (offset velocity determination) (Sattlerger, International Society of Exploration Geophysicists, 1973). MVD velocities show consistent along the line, and with
