【摘要】 准噶尔盆地南缘天山山前坳陷带,由于其特殊的地表和地下地质条件,地震勘探难度很大。近年来,随着对地震资料的不断深化认识,总结出了一套针对南缘的野外采集技术,即精细踏勘及遥感配套选线选点技术、以微测井为主的配套表层结构建模技术、灵活多变的激发接收技术、宽线长排列观测技术和基于照明分析的观测系统设计技术等。利用这些技术,在南缘独山子地区,获得了反映地层真实构造形态和内部结构的资料。更多还原

【Abstract】 Tianshan piedmont depression belt in southern margin of Junggar basin is of peculiar surface and underground geologic conditions,so its seismic prospecting is very difficult.In recent years,with the deepening of available data understanding,a set of field seismic data acquisition technologies suitable for the southern margin are summed up.They are: the fine reconnaissance and remote sensing supporting line selection,the surface structural modeling supported by micro-logging,flexible shooting and receiver,wide line and long array observation as well as lighting analysis-based observation system.Using these technologies in Dushanzi area of the southern margin,the data showing real strata structural forms and inner structures are obtained.更多还原
