The authors of this paper hold that the mechanism of abnormal pressure is related with disequilibrium compaction, aquathermal expansion, hydrocarbon generation and better sealing strata.

超压异常的形成与不均衡压实、水热增压、烃类的生成及存在较好的封闭层有关。

Compaction disequilibrium or hydrocarbon generation is main controlling factor of different phases for the development and evolution of overpressure.

压实不均衡和生烃作用分别是本区超压发育、演化不同阶段的主控因素。
