| 摘 要： | 针对通-南-巴地区山地工区复杂的地表结构和地质构造造成的地震施工难题,结合表层结构调查进行了激发试验确定了激发岩性、激发井深及炸药量等参数,确保主要目的层的地震波反射主频,拓宽有效波频带,提高纵向分辨率,以获取高信噪比地震资料;同时进行了基于地质模型及地震正演模拟的观测系统参数的设计,最终达到了突出有效反射,得到复杂构造信息的目的。

| Abstract: | Tong-na-ba area is a mountain area, where the complicated surface and underground structures have caused great difficulties in seismic exploration. This paper presents the seismic data acquisition method and experience in the mountain area. The emphasis is placed on surface structure survey, shot and receiving experimentation. The design principles and the illumination method are expounded with an example given. Practice shows that the acquisition method presented in this paper is helpful to the improvement of seismic data quality in the mountain area. |
