摘　　要：在二维地震测线施工时,若遇到村镇、水库等大型障碍区,通常将二维测线进行弯折处理以规避障碍。但是在测线弯折处,资料的共中心点(CMP点)通常会发生离散。利用Python语言编程,对测线弯折段的共中心点点位实现了自动计算,并对CMP离散度的符合率实现了自动分析。该程序可以更好地指导二维测线的弯折方式,在实际工作中取得了良好的效果。During the construction of two-dimensional seismic survey lines,if large obstacle areas such as villages,towns and reservoirs are encountered,the two-dimensional survey lines are usually curved to avoid obstacles.However,at the bend of the line,the common middle point(CMP)of the data usually disperse.By programming with Python language,the common middle point of the curved section of the survey line is automatically calculated,and the coincidence rate of CMP dispersion is automatically analyzed.This program can better guide the curved method of the two-dimensional survey line,and has achieved good results in practical work.
