【摘要】 共反射面元(CRS)叠加与常规共中心点(CMP)叠加相比是一种崭新的叠加方法。它是一种不依赖于宏观速度模型的零炮检距剖面成像方法,它的实现只依赖于3个波场属性参数的确定。共反射面元叠加通过将来自菲涅尔带范围内的反射波沿着叠加面求和,进而扩大叠加次数,达到增强反射信号能量、提高地震反射波的叠加成像质量的目的。实际地震资料处理结果表明,共反射面元叠加法能够提高剖面的信噪比、增加反射波同相轴的连续性。更多还原

【Abstract】 Common Reflection Surface(CRS) stack,a new stacking technique compared with conventional common midpoint(CMP) stack,is a zero-offset profile imaging method independent of macro-model.CRS stack depends on determination of three wave-field attributes,makes a summation using reflections along the stack surface,and increases the stacking numbers from Fresnel zone,in order to boost up signal energy and improve the stack imaging quality.The real seismic data processing indicates that this method can increase both the ratio of signal to noise in profile and the continuity of reflective events.更多还原
