英文摘要：

The geological conditions in northeastern Sichuan are complicated by the coexistence of complex mountainous terrain, deep burial of exploration targets, and carbonate reservoirs. Guided by the notion of integrated seismic acquisition, processing, and interpretation for prediction of reservoir, a study is carried out on such areas as the high-resolution seismic acquisition, high-fidelity seismic data processing, and deep carbonate reservoir prediction in complex mountainous terrain. A series of technologies are developed, including high-resolution seismic acquisition in complex mountainous terrain with reservoir-oriented acquisition design, high-precision positioning, high-density sampling, and saturated excitation as its cores, and high-resolution reservoir imaging and integrated seismic prediction suitable for reef flat reservoirs. They enhance the signal-to-noise ratio and resolution of seismic data and support the exploration of natural gas in the area.
