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。
With complicated surface and underground geologic conditions, several problem that Qaidam Basin has been facing with includes not-ideal static correction and low signal-to-noise while seismic data processing. Through the research on the technology of static correction in mountainous region and disturbing wave denoising, it is proposed that the method integrating static correction, migrated imaging with denoising is used to improve the quality of seismic profile in complicated structure area to reflect the underground geologic feature of complicated area. The primary effect has been obtained through application of this method in No.7 Lenghu and Shizigou areas.
