西沙海域南部多边形断层的发现及其分布特征与控制因素
Characteristics of Polygonal Faults Distribution and Analysis of Its Controlling Factors in Southern Xisha Offshore, South China Sea
摘要
Abstract
The polygonal faults in southern Xisha Offshore, South China Sea, were first discovered. On the basis of the 3D seismic data and the analysis of the controlling factors for polygonal faults development, it is concluded that the fine grained sediment strata from far source is the favorable development site in upper structure layer of Xisha Offshore. At the same time, channel sandstone, diagenesis and tectonism affected their development and distribution. Polygonal faults, combining with the deep tectonic fault, provided channels for fluid migration from deep hydrocarbon source rocks to the upper reservoir, or continued upward to the shallow strata to form natural gas hydrates.关键词
