| 摘 要： | 广角反射折射地震资料是较特殊的一类资料,其明显特点是:记录长,排列长,多种波场混合、反射能量强。用其进行深层勘探,可以大幅度提高深层地震资料的品质。本文从理论推导和模型试算上给出了反射资料不同于常规采集资料的处理方法，即反射波和折射波分离技术,大偏移距动校正叠加及正反演技术。尤其值得一提的是将这种海上的方法首次应用到了辽河地区陆上资料,并较好的提高了深层资料的品质。在浅层资料中大面积火山岩屏蔽区也取得较好效果。

| Abstract: | This paper presents the special processing methods used for wide-angle land seismic data through both theoretical study and model testing. They are different from conventional ones in the following aspects: separation of reflection and refraction waves, long offset NMO and stacking and forward modeling and inversion. These processing techniques have been applied for the first time to land seismic data from Liaohe areas, resulting in greatly improved quality of the deep formation and better imaging of the shallow layer obtained in the volcanic-shielded area. Wide-angle reflection and refraction seismic surveys were carried out in the Liaohe area using the maximum offset of 6500m and with the target around 2000ms. In the processing, we adopted the ~p transform and the high-order normal moveout correction. |
