【摘要】 研究区域位于山西中隆北部吕梁隆起北端宁静向斜之北西翼,区内地形复杂,相对高差244.6m,地层呈单斜产出,走向NNE-SSW向,倾向SE,倾角51°～42°,属急倾斜煤层。这种地质条件下三维地震勘探存在的非均匀介质成像、山区静较正、共中心点偏移,资料采集质量和资料处理等问题,通过正确的观测系统设计、高密度数据采集,可以取得高质量的成果资料。更多还原

【Abstract】 In the northwest wing of Lvliang ridge in the middle of Shanxi,the landform(topography) is complicated,with 244.6m relative height differences,monoclinic structure,NNE-SSW direction,and SE 51°-42° trending,which belongs to steep coal seam.Under this geographic condition,there are problems,including inhomogeneous media reconstruction,migration of mountain areas static correction and common midpoint,data collection quality,and data processing,in the 3D seismic exploitation.The high quality of findings can be achieved by correct observation system design and high density data collection.更多还原
