沙漠区特殊的表层地质结构使地震工作方法变得十分复杂,加上有如准噶尔盆地那样巨厚的沉积岩(深15000m,相应于6～8秒的反射时间)以及深达一、二百米的潜水面,从而较之其他的大沙漠更为困难。问题是,如何在强烈的干扰背景中逐步地把信号精选出来,其主要矛盾在于提高反射资料的信噪比。 The special surface geological structure of the desert area has complicated the seismic working methods. Coupled with the thick sedimentary rocks (depth 15000m, corresponding to reflection time of 6 to 8 seconds) and submerges of 1,200 meters deep in the Junggar Basin Surface, which is more difficult than the other big deserts. The question is, how to pick out the signal step by step in the background of strong interference, and the main contradiction is to improve the signal-to-noise ratio of the reflected data.
