【摘要】 在二维地震勘探中,以炸药为震源的野外资料采集施工,由于障碍物等客观原因,不能正常钻井放炮时,根据勘查区设计任务书的施工参数,可以画出变观模板,它具有直观快速的变观作用,野外所遇到的不同距离的障碍物,可以通过变观来避开,起到不丢失地质体保证叠加次数的作用。变观模板具有实际应用价值,给野外施工带来方便。更多还原

【Abstract】 In two-dimensional seismic exploration,the field data collection by explosive source,due to obstacles objective reasons,can not be normal drilling and shooting,according to the construction parameters of design task books in the prospecting area,we can draw translocated observation system template,it is the role of intuitive and fast,the obstacles in different distances can be avoided by transformation,the role of the geologicalbody is not lost and ensures superimposed number.Translocated template has actual application value,it is convenient to the construction field.更多还原
