摘　　要：针对川东北区复杂山地、深层勘探、碳酸盐岩层系的复杂地质条件,以面向礁滩储层的地震采集、处理和解释一体化攻关思路,在复杂山地高精度地震资料采集、高保真地震资料处理与深层碳酸盐岩优质储层预测等方面开展方法技术攻关与实际应用研究,形成了复杂山地高精度地震采集工艺技术(其中面向储层的采集设计技术、高精度定位、高密度采样和饱和激发为关键)、高分辨率储层成像技术系列与礁滩储层地震综合预测技术系列,提高了地震资料的信噪比与分辨率,有效地支撑了区内天然气勘探的发现与高效探明。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.
