| 摘 要： | 静校正问题是西部复杂地表地区地震勘探的瓶颈。层析反演静校正方法克服了折射静校正方法对稳定、连续折射界面的依赖，利用非线性反演方法能够获得较为准确的近地表速度模型，并计算出较为可靠的静校正量。通过对新疆一条二维地震测线的实际应用，证明在复杂地区层析反演静校正方法可以获得高质量的成像结果。

| Abstract: | The static correction problem is the bottleneck of seismic exploration in complex surface area of western region.Tomographic inversion static correction overcomes the dependence of stable and continuous interface.Using nonlinear inversion method,it can obtained accurate near-surface velocity model and calculated reliable static correction value.The practical application of Xinjiang 2D seismic line proved that tomographic inversion static correction method can get high quality imaging results. |
