摘要
本文通过对地震勘探检波组合特征函数的讨论,图解了检波组合时组内两相邻检波器接收有效波的时差△t对检波组合效应的影响,从而得出了△t越大,组合的效果也越差的结论。结合压制随机干扰,提出了适用于地形起伏较大的沙漠地区的一种检波组合方法──等高面积组合法。文中用实例说明了该方法的实用性和有效性。
Through discussing the characteristic function of geophone grouping we diagram the timedifference △t between the times needed by neibouring geophones' receiving effective waves underthe circumstances of geophone grouping,and the effect of △t on geophone grouping characteristics,which leads to the conclusion that the bigger the △t is, the worse the geophone groupingcharacteristics become. Under the condition of the suppression of random interference,we present away of geophone grouping-contour area gtouping that is suitable to strikingly undulating desertarea. In the paper we demonstrate the practical usefulness and the effectiveness of the proposedmethod through cxamples.
