静校正的重要性静校正是地震资料处理的重要环节。特别是广大的西北高原,因为长期处于侵蚀环境,使得地表出露岩性不同、风化程度也不同,潜水分布零星。再加上地形起伏,尤其是在一些古河床、古冲沟现在已被某些干燥砂土充填的地方,静校正值的变化相当剧烈。因此,多次复盖资料的迭加效果在很大程度上依赖于准确的静校正值。另外广大西北地区野外地震工作方法都比较复杂,如多井、多坑组合爆炸,炸药量大,每炮用雷管也多。然而由于这种复杂的施工方法没有一整套的设备条件的配合,往往不能保证启爆条件的一致,
The Importance of Static Correction Static correction is an important part of seismic data processing. Especially the vast northwestern plateau, because of long-term erosion in the environment, making the surface exposed different lithology, weathering is also different, diving scattered. Coupled with the undulating topography, especially in some ancient river beds where the ancient gully has now been filled with some dry sand, the static correction varies considerably. Therefore, the superposition of multiple overlay data relies heavily on accurate statics. In addition, the vast field of northwestern earthquake work methods are more complex, such as multi-well, multi-pit combination of explosions, large amount of explosives, each shot with more detonators. However, due to this complicated construction method does not have a complete set of equipment with the conditions often can not guarantee the same explosion conditions,
