Hydrocarbon Detection Techniques on Subtle Reservoir Exploration in Qiongdongnan Basin
Advanced Materials Research, 2011Subtle 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 ...

Geophysical properties of cap rocks in Qiongdongnan Basin, South China Sea
Marine and Petroleum Geology, 2000Abstract Based on measured petrophysical properties and statistical methods, relationship between petrophysical properties and well log and seismic parameters are established empirically to evaluate the quality of cap rocks in Qiongdongnan Basin. Good cap rocks show high density and low sonic travel time.

Cenozoic tectonic subsidence in the Qiongdongnan Basin, northern South China Sea
Basin Research, 2016AbstractA number of major controversies exist in the South China Sea, including the timing and pattern of seafloor spreading, the anomalous alternating strike‐slip movement on the Red River Fault, the existence of anomalous post‐rift subsidence and how major submarine canyons have developed.

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.

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 ...

The mechanics of continental extension in Qiongdongnan Basin, northern South China Sea
Marine Geophysical Research, 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.

Basin Research
In rifted margins or rifted basins, the structure of the basin is often complex due to the multistage development of fault systems. As we can only see the result of the basin evolution, it is difficult to judge the influence of early fault activity on ...

The high resolution sedimentary filling in Qiongdongnan Basin, Northern South China Sea
Marine Geology, 2015Abstract The high density (2 km × 6 km), high resolution (19 sequence boundaries) seismic reflection profiles and 42 industrial wells (including VSP data, gamma ray, sonic and density logs) are now available in Qiongdongnan Basin to the northwest of South China Sea.

Tectonic Subsidence of Qiongdongnan Basin and Its Main Control Factors
Chinese Journal of Geophysics, 2008AbstractBased on the data from 28 boreholes and the latest data of 3 seismic lines, the estimation of tectonic subsidence shows that the Qiongdongnan Basin (QDNB) experienced three episodes of rapid subsiding and one episode of slow subsiding in Cenozoic time.
