Hydrocarbon Detection Techniques on Subtle Reservoir Exploration in Qiongdongnan Basin [PDF]
Advanced Materials Research, 2011 Subtle reservoir is an important area of hydrocarbon exploration in Qiongdongnan basin. The reservoir hydrocarbon-bearing potential is one of the cores of this research, and the geophysical technology is the main research tool. In this paper, AVO, AVD, DR and seismic attenuation gradient techniques are carried out to evaluate the hydrocarbon-bearing ...

The tectonic evolution of the Qiongdongnan Basin in the northern margin of the South China Sea
Journal of Asian Earth Sciences, 2013Abstract Qiongdongnan Basin is a Cenozoic rift basin located on the northern passive continental margin of the South China Sea. Due to a lack of geologic observations, its evolution was not clear in the past. However, recently acquired 2-D seismic reflection data provide an opportunity to investigate its tectonic evolution.

The mechanics of continental extension in Qiongdongnan Basin, northern South China Sea
Marine Geophysical Researches, 2014Located in the intersection of NE-trended rifted margin of South China Sea (SCS) and NW-oriented Ailao Shan–Red River Shear Zone (RRSZ), Qiongdongnan Basin shows significant differences in geological features from west to east, indicating different mechanics of continental extension.

Abstract The Qiongdongnan Basin is a strongly overpressured basin with the maximum pressure coefficient over 2.2. Two types of vertical overpressure configuration can be identified by electronic logs and mud pressure, based on the calibration with the test pressure.

The evolution of the slope breaks in Qiongdongnan Basin and their controlling factors
Marine Geophysical Research, 2014Qiongdongnan Basin (QB) experienced three main tectonic stages in the Cenozoic: rifting, thermal subsidence, and accelerated subsidence. Corresponding to these stages, the slope breaks also underwent three different evolutionary stages, which differed in space and time between the east and west of QB.

The central depression of the Qiongdongnan Basin can be divided into the eastern and western sub-basins by the Lingshui–Songnan paleo-uplift. To the northwest, the orientation of the faults turns from NE, to EW, and later to NW; In the southwest, the orientation of the faults turns from NE, to NNE, and then to NW, making the central depression much ...

Simulation on Formation Mechanism of Qiongdongnan Basin
2019In this paper, the mathematic model of the thermal thinning mechanism of the lithosphere under the Qiongdongnan Basin was established. The process of thermal thinning in lithosphere during the early period since the Cretaceous and the continuous thinning process of the lithosphere during the late period was simulated.
