共散射点成像及其在低信噪比三维地震数据处理中的应用

根据地震旅行时的双平方根方程，采用叠前克体育运动人积分偏移原理，将地震道按产生的散射，在给定的偏移距范围内抽成道集，称为共散射点道集。然后对该道集进行速度分析、动校正和叠加，得到偏移地震剖面，邓共散射点成像。文中给出的实例证明了该方法的有效性。

Common scattering point imaging and its application to low S/N 3 D seismic data processing.

The common scattering point trace gather within the given offset is obtained by taking the dual quadratic surd travel time equation, the principle of prestack Kirchoff integral migration, and the number of scattering points. Then the trace gather undergoes velocity analysis, normal moveout correction and stack to bring seismic migrated section ( This is called scattering point imaging). Common scattering point is equivalent to common reflection point and results in very high signal noise ratio; besides it can be used to have correct velocity model. Consequently, the combinative use of common scattering point imaging, special noise elimination, residual static correction and so on will be very significant to the processing of low S/N seismic data. The example proves the method very effective.
