在高分辨率地震勘探中,能否采用组合一直是人们争论的问题。本文从震检联合组合原理及理论分析出发,结合大庆地区的实际资料,说明在石油地震勘探中,采用较小的组合距进行震检联合组合能压制低频和高频干扰,有利于提高地震资料的信噪比和分辨率。

It is argument that if array can be used in high resolution seismic exploration. Based on the principle of source and geophone uniting array and its theoretical analysis combined with the real data from Daqing survey area, this paper demonstrates that one can suppress low and high frequency noises using source and geophone uniting array with small array spacing. Thus the S/N ratio and resolution of seismic data can be improved.
