| 摘 要： | 夏盐南三维工区地表条件复杂，低、降速带变化大，静校正问题突出，为此，进行了针对性的系统研究。分别用折射初至静校正方法和表层模型静校正方法提供了2套静校正量。由于该区折射层变化频繁，折射波难以追踪，折射初至静校正方法没能得到好的应用效果；表层模型法将微测井和小折射有机地结合起来进行静校正量的计算，加上控制点较多，较好地解决了该区的静校正问题。 |

| Abstract: | Serious static correction problem is encountered due to the complicated surface settings and rapid variations of low velocity layer in the survey area in the south of Xiayan. Two set of statics are generated using refraction arrival static method and surface layer model static method, respectively. The refraction arrival static method fails in case of rapid variations of refractors. With advantage of uphole survey and shallow refraction survey, the surface layer model method succeeds in resolve static correction problem. Desired results have been achieved. |
| Keywords: | uphole survey shallow refraction survey model method refraction wave static correction low velocity layer (LVL) long wavelength |
