Abstract: The Xujiahe Formation fractured oil and gas reservoirs in the Sichuan Basin have broad exploration prospects. The existing seismic data mainly faces challenges of low signal-to-noise ratio and chaotic reflections. Traditional offset vector tile (OVT) domain imaging techniques are affected by acquisition factors, resulting in uneven coverage in various directions, which is not conducive to observing fractures from various directions. To address these issues, this study systematically optimizes pre-stack noise suppression, pre-stack depth domain velocity modeling, and imaging technology to significantly improve the imaging quality of the Xujiahe Formation reservoir and provide high-precision basic data for fracture prediction. The main innovative mainly include three components: (1) optimizing the traditional domain based pre stack noise suppression method, based on the rearrangement of shot domain data, reducing data redundancy and time of domain based sorting noise, and significantly improving the efficiency and effectiveness of pre stack noise suppression; (2) On the basis of grid tomography modeling of common offset gathers, combined with omnidirectional reflection angle domain grid tomography modeling, reasonably applying multiple offset gathers improves modeling accuracy and efficiency; and (3) the use of omnidirectional angle domain imaging technology compensates for shortcomings of traditional OVT domain imaging, such as uneven coverage in various directions and low imaging quality in far offsets, and improves the imaging quality of data. Empirical research based on the JY block in the Sichuan Basin shows that our method significantly improves imaging quality compared to traditional OVT domain results. The Xujiahe Formation imaging quality is significantly improved, the correlation between well seismic activity is enhanced, the ability to identify small fractures is enhanced, and the characteristics of fracture development are clearer. This research provides an efficient data processing technology system and practical framework for the exploring similar fractured oil and gas reservoirs.
