Abnormal pressure in the Nanpu Sag is prevalent,but its distribution in varying tectonic zones and its genetic mechanisms are rarely studied.So we depicted the architectural features of the pressure for varying tectonic zones in detail based on the data from 1 354 drill stem tests( DST),repeated formation pressure tests( RFT),and the well logging curves of 357 wells.The results show that vertically,the formation pressure system can be classified into three zones in the Nanpu sag,namely,the upper normal pres...
