中文摘要：
随着三维高分辨率、高精度及宽方位地震采集技术的应用,野外采集获取了大量观测数据,海量数据对地震处理方法提出了更高的要求.本文将编码思想应用于混叠数据处理,能够较好地在提高地震处理效率的同时,压制串扰噪声.不同编码方式及编码算子直接影响成像串扰噪声压制效果、成像精度、计算效率及存储.本文采用在频率域对炮集分频的编码方式,并将其应用在最小二乘偏移当中,通过模型试算分析了动态、静态及动静混合三种编码方式的优缺点,初步探讨了不同编码策略的适应性.
英文摘要：
With the application of three-dimensional highresolution,high precision and wide-azimuth seismic acquisition techniques,larger and larger field data are recorded which is highly demanding more efficient data processing techniques. In this paper,we propose several kinds of encoding methods for the blended data processing to improve the migration efficient and decrease the crosstalk. Different kinds of encoding approaches and operators affect the cross-talk suppression, imaging resolution, calculation efficiency and memory. We implement frequency-selection encoding strategy on shot-gather in the frequency domain and apply it to the leastsquares migration. By comparing the advantage and disadvantage of three different encoding（ the dynamic, static and mixing）strategies, we give the preliminary relationship between the encoding strategy selection and the quality of the raw blended seismic record.
