在沙漠地区采用打井放炮的办法,不仅成本高,而且效率低,若采用非炸药震源,可收到事半功倍的效果。物探局217队曾经使用可控震源在玉门花海半沙漠地区作过地震勘探工作,获得2秒以上的可靠反射。其中相当于第三系的反射,具有能量强、能连续追踪的特点。属于该区基底的白垩系反射,一般也能可靠追踪。在这种地区所采用的方法是50米点距、600米偏移距、48道接收、12次复盖、40 It is not only high in cost and low in efficiency to use well drilling and shooting in the desert area, but also can achieve a multiplier effect if non-explosive sources are used. The 217 Geophysical Bureau used seismic vibrations to do seismic surveys in the Yumen-Huaihai semi-desert region and obtained reliable reflections of more than 2 seconds. Which is equivalent to the reflection of the Tertiary, with strong energy, can be traced continuously. Cretaceous reflections belonging to the basement of this area are generally also reliably trackable. The method used in this area is 50 m pitch, 600 m offset, 48 receive, 12 cover, 40
