摘要： 从静校正量的计算过程和地震资料处理中的静校正过程推导出了由共中心点（CMP）参考面反算其对应高程的计算公式,认为CMP参考面对应用于计算RG时的静校正量的起算点高程的一个平滑面,即CMP参考面有确定的高程含义。在利用地震资料进行构造成图时,应利用叠加速度,找准高程平滑面以进行深度校正。

Abstract: CMP reference surface, i.e. a RG line of two dimensional seismic profile, is a time domain reference surface induced by two-step correction of seismic data processing. This paper presented theoretically the formulae for calculating corresponding elevation to common midpoint (CMP) reference surface from the procedure of static correction computation of seismic data processing. It is concluded that CMP refer-ence surface corresponds to a flattened plane of static correction starting-point elevation in RG calculation, that is, CMP surface is of a cer-tain elevation signification.

Key words: time domain, reference surface, CMP, static correction
