The overpressure states of sedimentary basin are multiform, and their evolutions are systematic. In the Damintun Sag, when the rate of overpressure generation was higher than the rate of overpressure release, overpressure built up, contrarily, with the termination of overpressure generation, overpressure diminished. The evolution of overpressure was dynamic in nature. On the basis of analyzing burial histories, hydrocarbon generation histories and heat flow histories, the process of overpressure evolution was simulated. Multiple-factor coupling of the overpressure evolution suggests that the compaction disequilibrium and hydrocarbon generation are the main controlling factors in different phases of the development and evolution of overpressure in this region.
