| 英文摘要 | Cold seeps in the Qiongdongnan Basin have been identified from three-dimensional (3D) seismic data, geophysical attributes, and in situ observations. Amplitude, dip, coherence and acoustic impedance attributes are employed to delineate the spatial variations of cold seeps across different layers by identifying faults, fractures and reservoir properties. These variations arise from the differences inside and outside of cold seeps due to the occurrence of gas hydrate, where mass transport deposits (MTDs) are widely distributed. The primary objective is to characterize the diverse features of cold seep systems, including seafloor features, plumbing systems, and their potential relationships with gas hydrates and shallow gas. Moreover, new remotely operated vehicle (ROV) dives have been utilized to distinguish two distinct chemosynthetic biological communities associated with methane bubble plumes. One community represents an active cold seep, characterized by abundant mussels and clams on or around carbonates, while the other is a paleo-cold seep that has been reactivated by gas hydrate drilling due to the leakage of trapped gas near the base of gas hydrate stability zone. All identified cold seeps exhibit weak amplitude anomalies, pull-up reflections, and chimney-like structures, which are located within high amplitude zones above local uplift in different sags of the Qiongdongnan Basin. Logging-while-drilling and coring data within these chimney-like structures have confirmed moderate to high gas hydrate saturations with diverse morphologies, as well as methane-related carbonates, indicating the presence of buried or active cold seeps. These findings suggest that cold seep activity is influenced by MTDs and that the upward fluid migration is closely linked to deep gas or shallow gas below the BGHSZ, which penetrate through MTDs along fault and fracture systems, suggesting pressure-controlled gas seepage. |
