【摘要】：针对塔里木盆地深层地震资料拼接处理面临的关键问题开展方法研究和对比试验,采用配套静校正、一致性处理、叠前多域逐步去噪等技术手段来解决静校正、一致性、信噪比等问题。在此基础上,进一步通过高精度拉东变换、聚束滤波结合近道内切除消除多次波的影响,达到去伪存真的地质效果;然后通过共反射面元叠加成像、τ-p信号增强、低频拓展等深层信号增强技术改善深层成像。通过以上关键处理技术的综合应用,可以有效提高塔里木盆地深层大剖面地震拼接剖面的品质。
[Abstract]:In view of the key problems in deep seismic data stitching in Tarim Basin, the method research and contrast test are carried out, and the static correction and consistency are solved by supporting static correction, consistency processing and multi-domain progressive de-noising before stack. On the basis of this, we further eliminate the influence of multiple waves by means of high-precision Radon transform, spotlight filtering combined with near-channel resection, so as to distinguish false objects and preserve the geological effects of real things. Then, 蟿 -p signals are enhanced by co-reflection surface superposition imaging. Through the comprehensive application of the above key processing techniques, the quality of seismic splicing sections of deep deep large sections in Tarim Basin can be effectively improved.
