Abstract：The Low Velocity Layer zone (LVL) in desert area is main reason causing serious high-frequency attenuation of seismic data. For that reason, it should adopt direct wave data of uphole survey,use optimum Wiener filtering method and compute inverse filter for compensating absorption of LVL in different thickness to compensate the high-frequency components of seismic data. The paper briefly introduced the principle of inverse filter for compensating absorption and applied the inverse filter for compensating absorption to process the common stack data. The correlation between the pre-and post-processing data showed the spectral ener- gy after the processing of compensating absorption can significantly broaden the bandwidth of dominant signal-to-noise of stack data in targets, increase relative energy of high-frequency components and improve the resolution of stack section. Meanwhile, the method can also protect the low-frequency components. Using the method to compensate the high-frequency attenuation of seismic signal is better and easier than inverse-Q filter.
