地震勘探組合法中,采用很小的組內检波器間距离吋,組合法仅只起提高接收仪器灵敏度的作用;检波器間距較大情况下,微震干扰可以看作相互独立的随机干扰来研究;但在間距不太大但也不能认为等于零时,組合方法的效果却是个尚待討論的問題。本文假定微震是由传播方向随机改变的平面波形成的,用概率論方法討論了組合地震法对徽震干扰的压制效果。
Seismic exploration combined method, using a small group within the distance between the detectors, the combination of law only to improve the sensitivity of the receiving device role; geophone spacing larger cases, microseismic interference can be seen as independent random interference to study; However, when the spacing is not too large but can not be considered equal to zero, the effect of the combination method is an issue to be discussed. In this paper, it is assumed that microseism is formed by a plane wave that randomly changes in the direction of propagation. Probability theory is used to discuss the suppression effect of the combined seismic method on the emblem-based seismic disturbance.
