摘要

高倾角地区(地层倾角40～70°)一直是三维地震勘探的难题,特别是在地表建筑物极复杂区(占工区的95%)实施三维地震勘探,显得难度更大。本文从观测系统设计、炮点、检波器的特殊布设及特观设计上,论证了其可行性。对高倾角且建筑物密集区的三维地震勘探进行了探索,并取得了可喜的成果。
Three dimensional seismic prospecting in the high obliquity area (stratum obliquity of 40°～70°) is always a conundrum, especially in the areas of complicated building (building area account for 95% of total working area) looks more difficulty. In this paper, from designing of observation system, shotpoint and special arrangement of geophones, demonstrated its feasibility. The author probed into 3D seismic prospecting in high obliquity building compact districts and the results are delightful.
