| Abstract: | Based on the research work of fluid pressures calculated with computer from data of acoustic log, the two-zone structures of abnormal high pressure ( AHP ) in the western Liaohe basin and the relations between overpressure and sedimentary facies or geological structures have been discussed. There is a geological and physical boundary surface between normal pressure zone and overpressure zone in the area where the AHP occurs. Finally, this paper proposes the indicator significance of the boundary surface and the origin of the superpressured zone. |
