Characteristics of Hydrocarbon Migration and Accumulation and Their Petroleum Geological Significance on the Northern Slope of Lingshui Depression, Qiongdongnan Basin
This analysis reveals hydrocarbon accumulation potential in the northern slope of Lingshui Depression, indicating high-value exploration targets.
Key Points
The study aims to analyze hydrocarbon migration and accumulation characteristics in the northern slope of the Lingshui Depression to enhance exploration strategies.
Utilized latest drilling, logging, and 3D seismic data.
Applied the Hubbert fluid potential model for analysis.
Reconstructed paleoburial depth and fluid potential fields.
Developed a hydrocarbon accumulation model based on geological conditions.
Identified high-potential zones on northern and southern sides of the slope during Late Miocene.
Delineated oil and gas migration and accumulation units.
Determined central migration and accumulation unit as promising exploration target.
Confirmed hydrocarbons were supplied from two sources, with three-dimensional migration.
