OVERPRESSURE DEVELOPMENT AND HYDROFRACTURING IN THE YINGGEHAI BASIN, SOUTH CHINA SEA
Journal of Petroleum Geology, 1999Intensely 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, 2003Abstract 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 ...

Tectono-thermal modeling of the Yinggehai Basin, South China Sea
Science in China Series D: Earth Sciences, 2001Based 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 ...

Effects of Overpressured Fluid Flow on Petroleum Accumulation in the Yinggehai Basin
Acta Geologica Sinica - English Edition, 2004Abstract 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 ...

Abstract In recent years, shallow-marine fans have attracted considerable attention because they may serve as valuable targets in hydrocarbon exploration. By integrating 3-D seismic, well log, core, and other measured data, this study analyzed the sedimentary characteristics and factors controlling the deposition of shallow-marine fans in Member #1 ...

Abstract Overpressure systems are widely developed in the central depression and palco‐uplift in the Yinggehai and Qiongdongnan basins. They can be divided into three types according to the origin of abnormally high formation pressure in the reservoirs, i.e. the autochthonous, vertically‐transmitted and laterally‐transmitted types.

Natural gas generation model and its response in accumulated fluids in the Yinggehai basin
Science in China Series D: Earth Sciences, 2003The natural gases found in the Yinggehai basin have nitrogen gas content ranging from 3.5% to 35%, and carbon dioxide content ranging from 0.1% to 93%. The nitrogen and CO 2 contents show a wide variation even in the same gas field. The natural gas generation and evolution model has been established based on the relationship among the contents of ...

Natural Gas Charging and Pressure Evolution in the Slope of the Yinggehai Basin
The abnormally high pore pressure is developed in the Huangliu Formation reservoirs of the Ledong X structure on the slope of the Yinggehai Basin. The present maximum pressure coefficient reaches 2.3, indicating a strongly overpressured system. The development and evolution of reservoir overpressure are closely associated with multi-stage natural gas ...openaire +1 more source
Intense fluid overpressure in the eastern slope of the Yinggehai Basin, South China Sea
The gas-bearing Yinggehai Basin in the northern South China Sea is characterized by high pressure and temperature conditions. The Miocene strata in the eastern slope exhibit intense overpressure with a pressure coefficient exceeding 2.2. Understanding the characteristics of overpressure and clarifying its causes are very important for natural gas ...Baibing Yang, Qingfeng Meng, Fang Hao
