Examples
- According to characteristics of the seismic data from the low snr region with complex surface , this paper is started from solving the static correction problem and reasonable eliminating all kinds of disturbance in the seismic data from the low snr region with complex surface . through the whole process of seismic data processing which includes a series of processing methods that are suitable for the low snr region , namely , from the choosing of the floating base - level , the static correction in the field and indoors , the eliminating of all kinds of noise before and after stacking , the velocity analysis with high - resolution , the reasonable techniques of deconvolution before stacking and wavelet processing after stacking , to the method choosing of the high - resolution stacking and the reasonable and accurate offset imaging , a set of the complete and effective flow for processing seismic data from the low snr region with complex surface are finally formed , which can meet the need of explo
本文针对复杂地表低信噪比地区地震资料的特点，以解决复杂地表低信噪比地区地震资料静校正问题及合理剔除各类干扰为出发点，在整个地震资料处理过程中，从浮动基准面的选取、野外及室内静校正、叠前叠后各类噪音的去除、高精度速度分析、合理的叠前反褶积及叠后子波处理技术、到选用高精度的叠加技术及合理准确的偏移成像方法等一系列适合于复杂地表低信噪比地区的处理方法，最终形成一套较完整且有效的针对复杂地表低信噪比地区地震资料的处理流程。
