Abstract：The paper adopted method using L, 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 according to minimum standard of L, norm,then the time-dip is calculated and interpolation is carried out.The method is suitable to both linear or nonlinear interpolation and event interpolation with equal 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.
