摘　　要：针对浅层地震反射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正拉伸畸变严重等特点,进行了叠前去噪、拉伸畸变切除及反射系数畸变切除、静校正、浅层偏移成像等方法的研究,并在实际资料处理中见到了明显的效果。In shallow layers,seismic-reflection signal is characterized by big effect on reflection coefficient along with the variation of arrival angle,large influence from first arrival and source factors,serious surface-wave interference,being sensitive to velocity,and severely anomalous stretch of normal moveout.So,many methods are studied,including pre-stacking denoise,eliminating anomalous stretch and reflection-coefficient distortion,static correction,and migration imaging.These methods are applied to seismic-data processing and an obvious effect can be obtained.
