Application of wavelet deconvolution to seismic interpretation in tahe oilfield 子波反褶积在塔河油田地震解释中的应用
Signal can not be created but be enhanced by attenuating many kinds of noise from field by processing , so , is ridiculous to say , " do n ' t worry , we can get anything we want by processing " 值得说明的是,迭代法噪音衰减、迭代法振幅补偿和串联反褶积这三个处理过程不是彼此孤立的,而是相互联系的,这三个处理过程也是有机的组合,起到互补效果。
The main influence factor of seismic vertical resolution is very complex , manufacture and scientific research is main care the vertical resolution . besides of the noise , the vertical resolution is depend on the wavelength , we can enhance it through improve the shot condition and deconverlution 而影响纵向分辨率的因素比较复杂,也是生产和科研比较关心的问题,除去干扰等因素,纵向分辨率主要取决于波长,可以通过改善野外激发条件和反褶积来解决。
In this paper , the authors used different gliding windows to perform euler deconvolution on magnetic profile data or 2 - d model , probed into the relationship between structure indices and solutions and the method for eliminating the poor solution on 2 - d model by mathematical statistics 摘要为了利用欧拉反褶积进行快速计算,提出了多个大小不同的滑动窗口进行多次覆盖的算法,对高精度磁测剖面逐点反复计算,并根据统计学原理从大量计算结果中剔除坏解,保留合理的解;还根据2 - d模型讨论了结构指数与欧拉反褶积的结果的关系。
