Application of Seismic Exploration Technology in Deep Water Areas of Qiongdongnan Basin
The Lingshui Depression is an important Hydrocarbon generating depression in the western South china Sea,with enormous resource potential and broad exploration prospects.multiple gas fields and gas bearing structures Have been discovered in this area,revealing active oil and gas accumulation and superior reservoir conditions.However,existing seismic data is no longer sufficient to meet the exploration needs of new targets.The seismic signal-to-noise ratio in the slope break area is low,the imaging is blurry,the continuity of seismic phase axes is poor,and the imaging of cross-sections and structural boundaries is not clear enough.We Have carried out seismic data research on the above-mentioned issues,focusing on multiple wave attenuation,improving signal-to-noise ratio,and precise velocity modeling,providing High-quality seismic data for the implementation of fine targets in the area.
