摘要
随着油气勘探的不断深入 ,浅层地震勘探也成为一些地区扩大生产储量的一个重要途径。然而浅层地震信号具有反射系数随入射角变化大 ,受震源因素、初至影响大 ,面波干扰严重 ,对速度敏感以及动校拉伸畸变严重等特点。浅层地震资料处理有一定的难度。对这些问题展开初步探讨 ,得到了一些有益的认识。
As the development of petroleum exploration goes in depth, shallow seismic exploration has become an important way to enlarge reserves in some areas. However, seismic signals from shallow layers suffer from surface waves and NMO stretching distortion. They are sensitive to velocity and easy to be affected by factors of seismic source and first break. The reflection coefficients of the signals vary with incidence angle. Therefore, shallow seismic data processing is more difficult. This paper discusses issues of shallow seismic data processing.
