| 摘 要： | 在二维地震勘探中,当地表遇到不能钻井放炮的障碍物时,如果要满足设计叠加次数,就必须采取变观激发的办法。变观激发时如何合理选择最大炮检距,保证区内浅、中、深目的层达到最大叠加次数,且在地层倾向未知的情况下,可通过变观激发试验,从监视记录上直接确定其下倾方向激发上倾接收的施工方法。

| Abstract: | In the two-dimensional seismic investigate explore, when there are obstacles which cumber boring holes for exploding on the Earth＇s surface, have to adopt the way of changing view exploding to meet designed folds. When changing view exploding, how to choose the maximum off-set reasonably, ensure obtain the designed folds on the reflect stratum in shallow, medium, deep area, and in case unknowning stratum proneness, by making a test of changing view exploding, from the surveillance record directly confirm geologic stratum proneness and the maximum off-set. |
