在以往数十年的反射法地震勘探工作中,经验告诉我们,在潜水面以下爆炸时,激发条件最好。这点,在使用多次覆盖技术以前更为重要,因为记录的质量直接决定单次剖面的质量。但是在潜水面深达100多米的大沙漠中,打井困难,而且深井激发的效果究竟如何尚未经实践证实;浅并组合爆炸及联合组合法,虽已得到应用,但较之深井是否优越也需进一步探讨;另外一般情况下,浅井爆炸后的干扰比较强,因之对干扰波的压制问题是改进资料质量的关键问题。本文讨论了在方法上所采取的措施,并从理论及实践中证实其效果。
In the past decades of reflection seismic exploration work, experience tells us that the best when excited below the diving surface. This is even more important before using multiple overlay techniques because the quality of the record directly determines the quality of a single profile. However, it is difficult to drill well in the deep desert with the depth of more than 100 meters and how the effect of deep well stimulation has not yet been proved by practice. Although the combination of shallow and combined explosion and its combination has been applied, In other cases, the interference after shallow well explosion is relatively strong. Therefore, the suppression of interference waves is a key issue to improve the quality of data. This article discusses the measures taken in the method, and from the theory and practice to confirm its effectiveness.
