Results The mechanism of abnormal pressure is related with disequilibrium compaction, increasing of fluid volume and decreasing of pores.
结果超压异常的形成与不均衡压实、孔隙流体增加、孔隙体积减小有关；
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。
The result shows that equivalent depth method has a good effect on the layer with abnormal pressure, which the one-dimensional compaction theory is more applicable.
结果表明，等效深度法对于存在异常压力层段的地层效果比较好。而一维压实理论则具有较好的适用性。
