摘　　要：鄂南地区具备“多层含气、立体成藏”的特征,资源潜力较大。通过钻探,揭示了该工区发育致密气、煤层气、页岩气等多个增储领域。上古生界成藏条件有利,探井已获得工业气流,具有较大增储潜力。工区目的层信噪比低,能量弱,构造复杂,成像困难,本文针对性地采用精细静校正技术、叠前高度保持有效波振幅的可靠噪音衰减方法、多属性一致性处理等手段来提高地震剖面成像质量。The Erdos South Region has the characteristics of“multi-layered gas bearing and three-dimensional reservoir formation”,and has great resource potential.Through drilling,multiple storage areas such as tight gas,coalbed methane,and shale gas have been revealed in the work area.The conditions for reservoir formation in the Paleozoic era are favorable,and industrial gas flow has been obtained from exploration wells,which has great potential for increasing storage.The signal-to-noise ratio of the target layer in the work area is low,the energy is weak,the structure is complex,and imaging is difficult.This article specifically adopts fine static correction technology,reliable noise attenuation methods that maintain effective wave amplitude at pre stack height,and multi-attribute consistency processing to improve the quality of seismic profile imaging.
