应用叠前时间偏移/反偏移与CRS-OIS叠加削弱倾角歧视影响
数据规则化 噪声压制 倾角歧视现象
2015/12/3
为了更好地削弱倾角歧视影响, 将叠前时间偏移/反偏移与输出道成像方式的共反射面元叠加算法(Common Reflection Surface Stack by the Output Imaging Scheme,以下简称CRS-OIS)相结合,把常规预处理后的地震数据进行叠前时间偏移映射到成像空间,在该空间内实施CRS-OIS处理,再用相同的速度场将其反偏移到叠前数据空间.基于这种处理流程不仅得到...

本文是对非线性规划问题提出的一种算法，该算法把模拟退火算法应用到CRS算法中，根据模拟退火算法每一次迭代都体现集中和扩散两个策略的平衡的特点，使CRS算法更能够搜索到全局最优解，而不会陷入局部最优解。最后把提出的算法应用到两个典型的函数优化问题中，结果表明，算法是可行的、有效的
Common reflection surface by output imaging scheme (简称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。该方法不仅能够输出一张高质量的叠加剖面，同时亦能够得到高质量的叠前道集。本文将CRS-OIS方法的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。
