在沙漠地区开展地震勘探有两个突出的困难:第一,地表地震地质条件很差,起伏不平的风成沙丘不仅会强烈地吸收地震波,而且会产生各种干扰波,难以得好地震资料。第二,水源缺乏,交通困难,勘探人员的吃住问题不易解决。因此,要开展沙漠区的地震勘探,首先要解决好野外工作方法和设备问题。就野外工作方法而言,有以下几点值得注意:1.必须认真踏勘选线。沙漠里分布着许多沙丘,它们大体可归结为两种类型,一
There are two prominent difficulties in carrying out seismic exploration in the desert. First, the surface geological conditions of the earthquake are very poor. Uneven wind dunes not only absorb the seismic waves intensely, but also produce various kinds of interference waves, making it difficult to obtain seismic data. Second, lack of water resources and traffic difficulties make it hard for exploration personnel to live and work in the area. Therefore, to carry out the seismic exploration in the desert area, we must first solve the field work methods and equipment problems. In the field of work methods, the following points are noteworthy: 1. Must carefully survey line. There are many sand dunes in the desert, and they can generally be classified into two types
