摘要

以开滦林南仓矿业分公司-850区域高分辨率三维地震勘探为研究对象,根据其三维观测系统设计原理,考虑地物条件及区域构造特征,将测区沿该区向斜轴线分成南北两区,两区各自独立设计。北部采用规则观测系统,南部选用非规则观测系统,两者重复区域针对满覆盖、叠加次数、工作量等因素的影响,对观测系统进行适当的调整。观测系统除采用了规则观测系统参数外,还采用了“以道补炮、双边加密炮点、中间激发加密炮点”的方法,确保了勘探区内资料齐全,取得了较满意的观测数据。
Took the-850 area high resolution 3D seismic prospecting of the Kailuan Linnancang Mining Branch as a case study,based on the design principle of 3D field setup,considered ground objects and regional structure features,divided the prospecting area along the syncline axis into north and south two areas and designed separately.The north area used regular field setup,while the south area irregular field setup.In the overlapping region had relevant adjustment according to full coverage,stacking fold and workload.Except the regular field setup parameters were used,in order to ensure the complete data collection,measures of ″use recording channel to make up insufficient shotpoint,bilaterally shotpoint added,split shooting added″ were adopted,thus rather satisfied data were collected.
