摘要经过多年的发展、完善，折射静校正已成为一种非常成熟稳定的静校正技术。基于传统折射静校正方法机理，本文提出一套针对当前海量地震数据的技术策略：以高效的数据管理方式快捷读、写或调用初至数据；通过孔径约束方法显著减少查找数据的耗时，采用并行算法高速计算折射速度；利用优化迭代算法高效计算延迟时。从理论模型测试可知，在保证计算精度前提下，本文方法大幅度地提高了折射静校正的计算效率；实际数据应用表明，在硬件及所用数据量相同条件下，本文方法的效率是某商用软件的200~360倍。

Abstract：The refraction statics has become a very mature and stable approach after years of development and improvement.This paper puts forward an efficient refraction statics method with a set of strategies for nowadays massive seismic data based on the theory of refraction statics.A first-break fast invocation is achieved with an efficient management method;the refraction velocity parallel calculation is realized with the aperture-constraint method which reduces greatly data search time; and the delay time fast calculation is accomplished with the optimization of iteration algorithms.Model data tests show that the proposed method achieves a much higher calculation efficiency of refraction statics on the premise of ensuring the calculation accuracy.For real data tests,the proposed method realizes a calculation efficiency 200~360 times faster than that of a commercial software in the condition of the same hardware and the same data volume.

Key words： refraction static corrections refraction velocity delay time aperture constraints
