“…Array acoustic logging is widely used in new wells, and the fluid factor extracted from it is a good method for gas layer identification in conventional oil and gas fields. In recent years, more and more attention has been paid to natural gas hydrate and its associated gas reservoirs (Boswell and Collett, 2011;Yin et al, 2016;Xie et al, 2022). As a number of NGH reservoirs are present either with a gas layer or water layer, there are similar properties to conventional oil and gas reservoirs in the associated gas reservoirs.…”

“…The focus of this study is a hydrate test area located in the Shenhu Sea region of the South China Sea (Figure 1). The study area is situated within the Baiyun Depression, which forms part of the Pearl River Estuary Basin and is positioned between the Xisha Trough and Dongsha Islands [27] at a water depth of 1342 m. The geological setting of the study area is characterized by the interaction of several tectonic plates, including the Eurasian, Pacific, and Sino-Indian plates. The region exhibits both passive and active continental features, and displays a complex seafloor topography with varying elevations, characterized by the presence of erosion channels, sea valleys, seamounts, steep slopes, plateaus, alluvial fans, landslides, and other geological hazards.…”

“…The formation of hydrate causes changes in the pore size and distribution in sediments, and the maximum and average pore radii gradually decrease as the hydrate forms. Xie et al 26 used in situ NMR and other well logging data to investigate the pore size and hydrate formation properties between the gas hydrate zone and the upper water-saturated zone in the Shenhu area, South China Sea. Results indicate that the hydrate preferentially forms in macropores and mesopores, resulting in an increase in micropores.…”
