本文概述了目前弯曲测线的生产及资料处理情况.根据三维空间时距关系公式,推导出弯曲排列和直排列反射波旅行时间的差值公式.其中,核心部分是取决于炮点和检波点偏离中心解释线的距离和横向视倾角(?)_y的((y+b)/V)sin(?)_y 这一项,从而提出进行“弯曲校正“或”以直代曲校正”以后再叠加的弯曲测线资料处理方案.然后,探讨了在进行自动剩余静校正过程中同时实现弯曲校正和用解方程组来提取横向视倾角参数的方法.
This paper summarizes the current production of bending lines and data processing conditions.According to the formula of time-space relationship in three-dimensional space, the difference formula of travel time between curved arrangement and straight array reflected waves is deduced.Among them, the core part is determined by shots and detection points Deviation from the center of the interpretation of the line distance and horizontal tilt (?) _ Y ((y + b) / V) sin (?) _ Y this item, which proposed the “bend correction” Superposition of the curved line data processing scheme.Then, the method of simultaneous correction of curvatures and the solution of the equations of the transverse viewing angles to extract the horizontal viewing angle parameters during the automatic residual static correction process are discussed.
