摘要
在复杂探测地区采集的地震资料,原始记录的初至波常常出现"扭曲"现象。造成这种现象有多种原因,其中之一是横向上岩性速度变化剧烈。要想在这种地区得到优质的地震剖面,解决由于速度横向变化而引起的静校正问题,应采用变速场高程静校正计算方法。
Acquiring seismic information in the complex survey area,there often occur distorted phenomena in the first arrival wave of original record. There are many reasons that cause the phenomena,one of which is acute variety of lithologic velocity in horizon direction. In order to acquire good seismic cross-section in this kind of area and solve the static correction problems caused by velocity variety in lateral direction,it is vital important to utilize calculation method of the height static correction of variable-velocity field.
