【摘要】 本文采用L1范数求取道间时差技术求出剖面上每一样点的时间倾角,然后逐道进行倾角插值。当出现较多空道时,利用L1范数极小准则找出差值道集中绝对值最小点对应的移动时间,求出时间倾角进行插值。此法既能适应线性同相轴插值、非线性同相轴插值,又能适应等道距、非等道距插值。通过对合成记录及实际记录的处理表明,此法具有比常规道内插方法速度快、精度高、适应性强等优点。

【Abstract】 The paper adopted method using LI norm to calculate the time-difference to compute time-dip at each point of section and carry out dip interpolation trace by trace. When large gap exists,the shift time corresponding to point having minimum absolute value among differential-value gathers is found ac-cording to minimum standard of L1 norm,then the time-dip is calculated and interpolation is carried out. The method is suitable to both linear or non-linear interpolation and event interpolation with e-qual or unequal group interval. The synthetic and real data processing showed that comparing with ordinary trace interpolation method the method has the advantages of high-speed, high-precision and good suitability.
