In order to solve the problems of low- resolution seismic data and the complex sand body distribution and overlapping relationships in the W1 well area of the Yingqiong basin, a comprehensive data processing process was developed based on three years of original data.This process includes pre- processing, denoising, migration, and bias post- processing.Duringthe bias post- processing stage, the compressed sensing frequency lifting method was applied to the pre- stack depth migration profile and compared with the blue filtering frequency lifting method and the zero- phase deconvolution frequency lifting method. The advantages of the compressed sensing frequency lifting method were demonstrated, and the application of the method to solve current geological problems proved its rationality in the subsequent development and implementation in the W1 well area of the Yingqiong basin.The results show that, compared with the other two frequency lifting methods, the compressed sensing frequency lifting method effectively preserves reliable low- frequency information below the main frequency while expanding the high frequency range and enhancing data resolution. By using the compressed sensing frequency lifting method of seismic data, the gas- water relationship becomes clearer, and the stacking characteristics of sand bodies can be accurately represented. This verifiestheir indicative significance in guiding subsequent oil and gas exploration efforts.As a new seismic data processing method, the compressed sensing frequency lifting method can better solve the problems of low seismic data resolution, sand body distribution, and complex overlapping relationships. Therefore, it is worth popularizing and applying in practical seismic data processing.
