Abstract:
A new method for flow unit division is proposed which combines sedimentology and the physical properties of a reservoir. The flow unit system is sub-divided into three hierarchies: flow unit, sub-flow unit and seepage zone. On the basis of elaborate ...

Discovery and Recognition of the Central Diapiric Zone in Baiyun Depression, Pearl River Mouth Basin
2006, 31(2): 209-213.
Abstract:
The Baiyun depression is a sub-unit of the Pearl River Mouth basin. In the center of this depression, fuzzy zones on 2D seismic profiles and low magnetic anomalies have been analyzed. A diapiric zone has been revealed, with a WNW directional distribu...
