摘要：

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. © 2019, Editorial Department OIL GEOPHYSICAL PROSPECTING.
