摘要
不需详细的低速带速度和厚度,利用零最小非纵距三维观测系统的近炮道取得井口时间,计算检波点浮动基准面校正量,以此为基础分别进行炮点、检波点静校正,分步校正到水平基准面。方法可靠,效率、效果明显。
No need of detailed speed and thickness of low-speed layer, the emendation of demodulation float datum plane was calculated just with reaching well mouth time recorded by zero-offset 3D observation system. On this condition, we emendated the explosion site and demodulation point to horizontal datum plane. This method is reliable and effective.
