Abstract: Jinghai Sag is located south of Chaoshan Sag in the Pearl River Mouth Basin, which is a Mesozoic and Cenozoic superimposed sag in the ocean-continent transition zone. As the new division of tectonic units in recent years, Jinghai Sag is the focus of current research in terms of Mesozoic geological characteristics and hydrocarbon exploration potential evaluation. This area is influenced by magmatic activity and has low-quality seismic data; it is difficult to use the current data to complete the structural interpretation research and evaluate sag exploration potential. In this paper, we used the integration of processing and interpretation techniques. We focused on using prestack SNR technology, wavelet processing and migration imaging technology to carry out test processing in this area. The processing effect was achieved by structural interpretation. The application showed that the technology used in Jinghai Sag was successful, and played an important role in studying structure and scale of Jinghai Sag and its adjacent area.

Key words: Pearl River Mouth Basin, Jinghai Sag, integration of processing and interpretation, Mesozoic
