Gas Hydrate Distribution Influenced by Sea Floor Slide and Canyon Erosion in the Shenhu Slope, Northern South China Sea Margin

Processes, Journal Year: 2025, Volume and Issue: 13(1), P. 193 - 193

Published: Jan. 11, 2025

The Shenhu area, located on the northern continental slope of South China Sea, is a confirmed gas hydrate-enriching region, but sedimentary unit, causative mechanisms, and evolution processes strata that contain hydrate remain unclear. Furthermore, recognition bottom simulating reflectors (BSRs) rests qualitative description; there no quantitative method for characterization or three-dimensional depiction BSRs. This review examines features key factors controlling distribution in based high-resolution sequence stratigraphy combined with drilling logging data from projects area. main findings this study include (1) BSRs are mainly distributed ridges slip blocks side slope, hydrates developing along thin layer (10–40 m) below stability zone, as by results; (2) strongly influenced presence chimneys, migration deepwater channels, erosion sedimentation canyons, all which directly indirectly related to accumulation, distribution, formation reservoirs; (3) sand factor generally less than 10%, accumulate areas where higher (4–10%). Hydrate saturation shows positive correlation porosity. research also identifies early Pleistocene erosion/resedimentation event controls non-homogeneous region. highlights role canyon slumping formation, offering new insights into impact dynamic geological accumulation. provides valuable knowledge future exploration global resource assessments.

Simulation of Diffusion Characteristics and Risk Analysis of Natural Gas in an Underground Confined Space: A Case Study

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: May 2, 2025

In recent years, gas leakage from buried pipelines has been an inevitable issue worldwide. The leaked can diffuse through the soil into adjacent underground confined spaces, such as sewage pipelines, thereby posing significant risks to human lives and property in event of a fire. To investigate diffusion characteristics natural semiconfined this paper establishes mathematical model for pipelines. study examines impact inlet velocity, flow water level height, vent hole size on within concentration manhole increases velocity (up 0.6 m/s), height rise, with magnitude increase gradually diminishing. Additionally, it was observed that significantly affects at upstream test points. contrast, its effect variations downstream points weakens. This also puts forward three-level early warning mechanism analyzes discusses influence above factors time manhole.
