| Abstract: | The abnormal high geopressure, one of the basic physical parameters of the active heat fluid in the continental marginal basin, north of the South China Sea, have been studied. The effective prediction methods were used after analyzing the contradiction of the sonic transit time and the observed geopressure. The mathematical model of normal compaction trend has been established in theory, which was used to calculate the geopressure coefficient and the sub-surface of the high geopressure and build the cross section of the geopressure chambers. The places favourable for the hydrocarbon accumulation were pointed out by analyzing the geopressure coefficient, gas potential and water potential. |
