【摘要】 能否有效地解决静校正问题是复杂地表地区地震资料处理的关键。对所存在的静校正量值根据空间变化可分解为长波长静校正分量和短波长静校正分量。不同分量对资料的影响各不相同。本文针对各种静校正方法的优缺点及应用条件,总结出一套利用现有的静校正技术,依次解决长波长静校正分量—大的短波长静校正分量—短波长静校正分量的静校正方法处理流程,并提出了相交测线闭合问题的解决方法。更多还原

【Abstract】 Static correction is the key to seismic processing in areas with complex surface conditions.Static correction value can be separated into a long wavelength static cor-rection component and a short wavelength static correc-tion component according to spacial variation.Different components have different impacts on data.Based on analysis of the advantages and disadvantages and applica-tion conditions of various static correction methods,a static correction processing flow chart is established by using current available static correction technologies tosolve successively the long wavelength static correction component,large short wavelength static correction com-ponent and short wavelength static correction component.A method is also presented to solve the problem of cross line closure.更多还原
