摘要
在可控震源施工过程中,伪随机扫描信号作为可控震源线性扫描信号的补充,主要用于城区或油田地区等对振动比较敏感的区域,以降低对建筑物可能造成的伤害。本文探讨了伪随机扫描信号在可控震源电控箱体上应用,对伪随机扫描信号与同等的线性扫描信号在激发能量上进行了对比,分析了伪随机扫描信号的应用可能对可控震源机械液压性能的影响。
As a back-up sweep parameter, pseudo-random sweeps has small application in vibrator seismic exploration. Pseudo-random sequences are calculated andtested for the purpose of reducing possible damage. But some points ,for example the energy comparison of pseudo-random sweep and line sweep, the influence analysis to the vibrator structure when pseudo-random sweep is used, are worthwhile to do further investigation. In this paper some tests were done to make these points more clear.
