江西省多数地区,地形地质构造比较复杂,只采用简单的地震常规方法,很难提高地震的地质效果和勘探精度,也很难完成地震普查找煤的任务。通过迭加方法试验和试生产实践证明,在我省一些地区采用多次迭加方法,不仅可以取得第三系底界面,而且还可以穿透红层的底砾岩这一高速屏蔽层,获得常规地震方法难于获得的上三迭系安源煤系地层底界面的反射波。这一波形比较突出,一般有2—3个强相位,能连续追踪。迭加时间剖面较清晰,反
In most areas of Jiangxi Province, the topography and geology structure is rather complicated. Only simple conventional seismic methods are difficult to enhance the geological effect and exploration accuracy of the earthquake, and it is also very difficult to complete the task of general survey and coal prospecting. Through the superposition method test and trial production practice has proved that in some areas in our province using multiple superposition method, not only can obtain the third line of the bottom interface, but also can penetrate the red layer of the bottom conglomerate the high-speed shield to obtain Reflected waves from the bottom interface of the Anyuan coal measure strata in the Upper Triassic, which are hard to be obtained by conventional seismic methods. This waveform is more prominent, there are generally 2-3 strong phase, continuous tracking. Overlay time section clearer, anti
