摘要: 柴达木盆地复杂的地表地质条件和地下地质条件,使其在地震资料处理中存在着严重的静校正和低信噪比问题。通过重点研究山地静校正、干扰波去噪技术,提出了利用静校正、偏移成像、去噪技术相结合的方法,以提高复杂构造地区地震剖面的品质,合理反映复杂地区的地下地质特征,该方法在冷湖七号、狮子沟等地区的应用,取得了初步效果。

Abstract: With complicated surface a nd underground geologic conditions, sev eral problem that Qa idam Basin has been facing with includes not-idea l sta tic correction and low signa l-to-noise while seismic data processing. T hrough the research on the technology of static correction in mounta inous region and disturbing wave denoising, it is proposed tha t the method integra ting static correction, migrated ima ging with denoising is used to improv e the quality of seismic profile in complicated structure area to reflect the underground geologic feature of complicated area. The primary effect has been obta ined through applica tion of this method in No.7 Lenghu a nd Shizigou areas.

Key words: complicated structure, static correction, denoising, imagining, Qaidam Ba sin
