【Abstract】 The reasons that cause anomalous pore pressures were analyzed. Characteristics of different types of anomalous pressure were documented. Two methods of pore pressure prediction from well logging data were introduced and compared to the results from well test. The techniques for pore pressure prediction from seismic data and from the combination of seismic and well logging were also discussed. Some key issues that should be solved were presented.更多还原
