            傅旦丹,何樵登:地震折射偏移,《石油地球物理勘探》,23(4)1988:460～467由折射初至精确地反演近地表表层结构,一直是折射解释和折射静校正工作的重要内容。本文提出一种能快速准确地给出折射界面的方法:首先在每一炮点处求得临界距离值及从炮点到临界点的旅行时;然后根据该旅行时用椭圆法来构制折射界面。该方法可利用多次覆盖资料,在只知道上层速度而不知道折射速度的情况下,能准确地给出折射界面的位置,能适应界面剧烈起伏和折射速度有横向变化的情况,并能顺利地求取准确的折射速度值。

            在那些风化层横向变化剧烈、相邻两个接收点之间静校正值差别很大的地区,采用常规的高程校正和根据小折射或微测井控制点资料作线性内插,已无法求得合适的基准面静校正值。在这种情况下,剩余静校正量已超过反射波波形的1/2周期,即使采用剩余自动静校正方法也不可能取得满意的效果。为了解决上述问题,人们曾提出采用拾取生产记录初至时间计算基准面静校正量的各式各样初至折射法。这些方法均可称为绝对折射法。此类方法的特点是必须确定真正的初至时间,且在计算中要求追踪同一层的折射波,否则就会造成静校正计算误差和出现不闭合的问题。相对折射静校正方法(RRS)则是从共炮点远道记录求取高速折射层的到达时间,并在小折射或微测井控制点数据控制下进行内插计算,求取各炮点和接收点的基准面静校正值。就同一炮记录而言,两道折射波到达的时间差可分为两个部分:一部分是由于地表风化层的变化造成的时差,而另一部分则是由于折射波沿折射界面滑行及由此高速...
