利用CRS-OIS实现噪声压制与数据插值
|
摘要
CRS-OIS是一种以输出道成像方式实现的共反射面元叠加成像方法,不仅能够输出一张高质量的叠加剖面,也能够得到高质量的叠前道集.将这一特色用于陆地二维地震数据处理的噪音压制与数据插值计算,理论与实际数据计算证实了该方法的有效性,体现出很好的应用潜力.
CRS- OIS is a common reflection surface (CRS) stack method performed by output imaging scheme (OIS).The feature of CRS- OIS that a high quality prestack gather can be obtained has been utilized in the 2D seismic data processing to suppress random noise and interpolate missing traces.The synthetic and real data examples prove the effectiveness of CRS- OIS on this aspect which shows a huge potential in application.
