摘　　要：地震采集方案的优化设计是地震数据采集的重要组成部分。基于地震数据互相关相似性的采集方案优化是以生产和试验数据为基础,模拟处理各种采集方案成果,计算成果数据与目标数据的相似系数,通过相似系数分析资料品质的一种定量分析方法。该方法考虑了资料品质、优化方案和采集成本三者之间的关系,减少了定性分析的误差,能够为选择优化的采集方案提供较好的决策依据。Design optimization is an important part of seismic data acquisition system. The acquisition system optimization based on the cross correlating similarities in seismic data is a quantitative analysis method for using the existing produetion and experimental data to simulate and process various acquisition schemes, calculate scaling coefficient between result data and objective data, by whieh analyze the data quality, on the basis of production and test data. This method takes account of the relations among the data quality, optimized acquisi- tion system and cost, thus reducing the errors caused by qualitative analysis, and providing better decision basis for acquisition system opti- mization as necessary.
