四川省石油局地调处

本文回顾了圆法校正,用数学方法推出了几种特殊情况下的偏移结果,给出了“偏移交换”公式,并进行了讨论。归纳出“以直代曲”方法,在此基础上提出了一种圆法校正工具的设计思想和参考意见。

After reviewing the method of circular correction, migration results in some particular circumstances are mathematically derived from and a formula for "migration transformation" is given and discussed in this paper. Moreover, a correction method of using straight line segments instead of curved ones is summarized and on the basis of that, the idea for designing a simple circular correction tool is presented and some pertinent comments are made.
