高保真叠前去噪技术分析

Analysis of high fidelity prestack denoising

对研究区地震资料分析评价,结果表明原始地震资料存在面波、折射波、随机噪声等干扰情况,对处理得到的资料存在着较大的影响。因此叠前去噪的质量好坏,成为研究区地震资料处理的难点。通过静校正分析得知,处理结果使得地表一致性静校正和非地表一致性静校正都较为良好,才能使得资料处理达到满意的效果,得到保真性较好的处理资料。

The seismic data analysis and evaluation in the study area show that the original seismic data contain disturbances such as surface wave,refraction wave and random noise,which exert great influence on the data obtained.Therefore,the quality of prestack noise reduction becomes the difficult point of seismic data processing in the study area.The static analysis indicates that the processing results of surface consistent statics and surface inconsistency statics are relatively good,which makes the data processing with better data fidelity.
