随着数字处理技术的发展,为进一步提高地震勘探的精度与效果,发挥地震勘探的潜力,对地震波在介质中传播速度的研究,显得愈来愈重要。近年来迭加速度的应用,对压制干扰,突出有效波,提高地震记录信噪比发挥了巨大的作用;用它来近似计算层速度,研究地下地层岩性变化和直接找油等也起了一定的作用。但由于迭加速度本身的局限性,如它不仅是炮检距的函数,还是地层倾角的函数,并要求地下地层为线性界面(即要求一次反射路径具唯一性),使其应用与求取受到限制。因此为使陡倾或复杂构造地区剖面能正确归位及进行地层岩性等地质研究,要求将
With the development of digital processing technology, in order to further improve the accuracy and effectiveness of seismic exploration, to develop the potential of seismic exploration, it is more and more important to study the propagation velocity of seismic waves in the medium. In recent years, the application of Diego acceleration has played an enormous role in suppressing interference, highlighting effective waves, and improving the signal-to-noise ratio of seismic records. It is also used to approximate the calculation of layer velocities, to study the changes in lithology of underground formations and to directly look for oil. Role. However, due to the limitation of the superposition acceleration, if it is not only a function of offset distance but also a function of the dip angle of the strata and requires that the underground formation be a linear interface (that is, it requires a unique reflection path), its application and retrieval limit. Therefore, in order to make the profile of the steeply dipping or complex structure area be properly repositioned and geologic research of stratigraphic lithology is required,
