炮—检点双向照明补偿逆时移偏移
Keywords: 地震波照明,照明补偿,逆时偏移
Abstract:
？在分析炮点及接收点照明度的基础上，利用双程波照明补偿对逆时偏移中的单炮成像结果进行照明补偿，不仅克服了单程波方程只对炮点进行照明分析产生的照明不足的问题，而且能有效地补偿因速度剧变造成的振幅畸变。通过理论模型计算和在阿姆河右岸地区地震资料的应用，证明该偏移方法对速度剧烈变化造成的成像振幅畸变具有较好的校正作用，适用于该区“三膏两盐”（从上往下地层依次为上石膏层、上盐岩层、中石膏层、中盐岩层、下石膏层、下盐岩层，俗称“三膏两盐”）结构造成的下伏碳酸盐岩成像振幅畸变地层的成像，提高了阿姆河右岸地震资料的成像处理质量。
