自从磁带技术引入地震勘探领域后,野外多次叠加的观测方法就迅速地取代了原来的简单连续的观测方法,成为反射地震法的常规方法技术,这是因为这种观测方法更能发挥磁带技术的作用,使地震勘探的方法效能产生一个质的飞跃。目前大量的实践结果证明,多次叠加能够较好地压制规则干扰和随机干扰,突出弱讯号和一些有意义的异常波;因此对研究深层和断层或扩展标准层都带来好处。同时还能在此基础上扩大观测排列,从而提高工作效率、速度分析精度和取得更好的校正资料。
Since the introduction of magnetic tape technology into the field of seismic exploration, the observation method of multiple superimposition in the field has rapidly replaced the original simple continuous observation method and has become a conventional method of reflecting seismic methods, because this observation method can better utilize tape technology The role of seismic exploration method to produce a qualitative leap. At present, a large number of practical results prove that multiple superpositions can suppress regular interference and random interference well, emphasize weak signals and some meaningful abnormal waves, and thus bring benefits to deep research and fault or extension of standard layers. At the same time, we can also expand the observation arrangement on the basis to improve work efficiency, speed analysis accuracy and obtain better correction data.
