等旅行时面共反射面元叠加的应用研究
|
摘要
本文基于克希霍夫成像理论,对共反射面元(CRS)叠加方法进行了深入分析,阐述了等旅行时面共反射面元叠加方法(CRS-OIS)原理及其测试效果。指出CRS-OIS是对于传统共反射面元叠加方法的重要改进,它简化了传统CRS叠加方法,可以同时得到信噪比大幅度提高的叠前道集与零炮检距成像剖面。该方法首次被用于南海深水二维地震数据处理,处理结果表明基底与莫霍面的成像品质得到明显改善,提高了剖面的可解释性。
A detail analysis on common-reflection-surface(CRS) stack method is performed based on a unified Kirchhoff imaging theory from which an output imaging scheme(CRS-OIS) is derived.The CRS-OIS greatly simplify the implementation of traditional CRS stack from which both an enhanced prestack dataset and enhanced ZO image can be achieved.Thus,it can be seen as a significant improvement on CRS stack method.In this paper,the CRS-OIS is applied to the real data acquired in South China Sea for the first time.The general improved image quality and improved interpretability of target events such as the base of Paleozoic and Moho in the ZO image fully demonstrate its effectiveness.
