Abstract：Liushouying uplift is located in the south of Liaodong Bay Depression and is surrounded by oil-rich depressions. In addition, several large oil fields have been found in adjacent areas. The study area has similar reservoir-forming conditions and shows positive exploration prospects. However, the original 2D seismic data has a low signal-to-noise ratio, and difficulties such as multiple wave development and fast lateral velocity change are encountered during data processing. As a result, high-precision imaging cannot be realized. Furthermore, as the study area has no well-logging data, fine structure interpretation and accurate structure mapping are hard to be accomplished. Therefore, on the basis of the GeoEast system, research and application of integrated processing and interpretation suitable for low exploration zones are carried out. Specifically, this paper adopts processing modules such as fidelity denoising, combined multiple wave attenuation, and layer-constrained grid tomography to improve the seismic imaging quality, which provides a data basis for the fine structure interpretation. Furthermore, the paper carries out a fine structure interpretation in zones without wells by learning structure modes and lithology combination characteristics from adjacent areas, and comparing the adjacent velocity model and average velocity spectrum model of seismic processing. The structural map got from average velocity spectrum model have effectively improved the mapping precision. The research provides important support for oil and gas exploration in this area.
