| 摘 要： | 通过对地震波在近地表附近双源传递机理的研究,论述了品质因数与激发井深的关系,并根据不同地区、不同品质因数,其地震波最大激发能量、最大信噪比与激发井深的关系曲线,给出了相应的激发深度.三维地震实例表明,地震波在近地表附近的双源传递与品质因数是选择地震波激发井深的重要因素,另外激发频率的增大,对激发井深的影响程度随之增大;观测同样频率的地震信号,存在小Q值地震波激发井深较大Q值激发井深相应变小的特点.

| Abstract: | By way of a study on the near-surface seismic wave dual transmission mechanics, the paper discussed the relation between the Q factor and shothole depth, then according to the maximum seismic shot wave energy, maximum signal-to-noise ratio and shothole depth correlation curves of different area, different Q factor, worked out corresponding shot depth. The 3D seismic prospecting instances indicated that the near-surface seismic wave dual transmission and Q factor are major factors to choose seismic wave shothole depth. Besides, the increasing of shooting frequency will enhance the influence on the shothole depth; the equal frequency seismic signal has the feature of the smaller Q factor compared with larger Q factor, the shothole depth accordingly shallower. |
