陆上高分辨率地震勘探炸药震源激发条件分析
|
摘要
从理论上分析了激发井深、虚反射效应、岩性与炸药类型的耦合关系等激发条件对地震勘探分辨率的影 响。利用周口盆地黄淮冲积平原、宜阳凹陷黄土塬和塔里木盆地沙漠区的高分辨率地震资料,分析了不同地表 条件下的激发因素,提出了在复杂地表条件下如何选择最佳激发因素,以获得最好的单炮记录的施工方法。
Aimed at the terrestrial hi-resolution seismic exploration with the surface setting featured by diversity and complexity, the effect on resolution of the coupled relations a mong excitation well depth, ghost reflection effect, lithology and dynamite type is analyzed theoretically. With combined the hi-resolution data of three different surface structures in prospect ion areas of Henan and Tarim basin, the excitation factors in different surface conditions and the dynamite ex- citation conditions are studied. How to select the optimum excitation factor in complex surface conditions is presented to obtain the seismic acquisition method of the best quality of single shot. The practical hi-resolution seismic acquisitions using the method obtain relatively good effect in Huanghuan Alluvial Plain, loess plateau form and desert.
