塔里木复杂地表区静校正问题的处理方法及效果

塔里森地区的静校正问题是提高地震资料处理质量的关键。本文针对塔里木地区的地热资料，总结了在解决复杂地表区静校正问题中所采用的几种方法，沙丘曲线静校正，全差分析射波静校正，扩展了互义互换法折静波静校；人工拾取大的静校正误差和自动剩余静校正等，这些方法都有它的适用性和局限性，但都见到了很好的效果。

Processing methods for complicated-surface static correction in the Tarim basin and the application effects

Static correction in the Tarim basin is the key to the improvement of seismicdata processing in the basin. We describe several good methods used to cope withthe static correction of seismic data in complicated-surface area. The methods include static correction by sand dune curve,full-difference static correct1on by refraction waves, refraction-wave static correction using the extrapolated generalizationreciprocal, manual pickup of obvious static correction errors, automatic residualstatic correction and so on. Although they have their own adaptabilities and limitations,they all result in good effect.
