Yinggehai basin gas exploration: Comparison with Jiyang depression

Journal of Earth Science, 2012
Yinggehai (莺歌海) basin and Jiyang (济阳) depression experienced similar tectonic evolution, which is mainly controlled by the strike-slip faults. The strike pull-apart basins are characteristic by multiple deposition cycles, migration of deposition and subsidence center, and diversity depositional systems.

Mechanism of diapirism and episodic fluid injections in the Yinggehai Basin

Science in China Series D, 2002
The diapirism in the Yinggehai Basin is a combined result of strong overpressure caused by rapid sedimentation of fine-grain sediments and the tensile stress field resulting from right-lateral slip of the boundary-fault. The diapirism showed multiple-stage, episodic nature, and caused intermittent counter-direction onlaps and changes in the thickness ...

OVERPRESSURE DEVELOPMENT AND HYDROFRACTURING IN THE YINGGEHAI BASIN, SOUTH CHINA SEA

Journal of Petroleum Geology, 1999
Intensely overpressured compartments are present in the centre of the Yinggehai Basin, South China Sea. In this part of the basin, a diapiric area can be distinguished from a non‐diapiric area; structures in the former area result from shale diapirism at depth, and from the movement of hydrothermal fluids at more shallow levels.

Overpressuring mechanisms in the Yinggehai Basin, South China Sea

AAPG Bulletin, 2003
Yinggehai Basin is an elongate Cenozoic rift basin on the northwestern margin of the South China Sea continental shelf. Its thick (17 km) basin fill is characterized by high geothermal gradient and high overpressure. Overpressure associated with nonequilibrium compaction mainly occurs at depths more than 2800 m at the basin center and more than 4000 m ...

Tectono-thermal modeling of the Yinggehai Basin, South China Sea

Science in China Series D: Earth Sciences, 2001
Based on the observed data, the average value of surface heat flow in the Yinggehai Basin is calculated and it turns out to be 84.1 mW/m 2 . The thermal evolution of the basin since the Cenozoic era has been attempted by tectono-thermal modeling. Three-phase extension made the basin become hotter and hotter, reaching its climax in paleo-temperature ...

Initiation and evolution of fault‐controlled slope‐parallel submarine channels: Miocene eastern slope of Yinggehai Basin, South China Sea

Basin Research, 2022
Submarine channels act as the main conduits for the transport of sediment to deep‐water basins by sediment gravity flows. The interplay between fault‐related deformation and the initiation and development of the channels is poorly known. Here, we present

Fluid Charging and Paleo‐pressure Evolution in the Ledong Slope Zone of the Yinggehai Basin, South China Sea

Acta Geologica Sinica - English Edition, 2022
Large numbers of gas reservoirs have been discovered in overpressure basins. Fluid charging has a close relationship with paleo‐pressure evolution, affecting the migration of gas reservoirs.

Heat flow and thermal modeling of the Yinggehai Basin, South China Sea

Tectonophysics, 2002
Abstract Geothermal gradients are estimated to vary from 31 to 43 °C/km in the Yinggehai Basin based on 99 temperature data sets compiled from oil well data. Thirty-seven thermal conductivity measurements on core samples were made and the effects of porosity and water saturation were corrected.

Large-scale turbidite systems of a semi-enclosed shelf sea: The upper Miocene of Eastern Yinggehai Basin, South China Sea

Sedimentary Geology, 2021
In addition to the continental slope and basin floor, gravity flow deposition on the shelf is increasingly attracting attention. In order to explore the environmental conditions and sedimentary rules of large-scale gravity flow deposition in shelf sea ...

Effects of Overpressured Fluid Flow on Petroleum Accumulation in the Yinggehai Basin

Acta Geologica Sinica - English Edition, 2004
Abstract  The Yinggehai Basin is a strongly overpressured Cenozoic basin developed in the northern continental shelf of the South China Sea. The flow of overpressured fluids in this basin has given rise to strong effects on petroleum accumulation. (1) The overpressured fluid flow has enhanced the maturation of shallow‐buried source rocks, which has ...
