Abstract: The basin-orogeny coupling theory was applied to study the abnormally high pressure in basin for the first time in this paper. The formation and distribution of abnormally high pressure were controlled by regional stress fields. In compressed basins, the key contributing factors for abnormally high pressure were compressive stress and charging of natural gas (or oil-gas), where the abnormally high pressure distributed zonaly or planarly. In extended and pull-apart basins, the abnormally high pressure was mainly resulted from thermal activities. In extended basins, the abnormally high pressure distributed in the shape of scattered points or restricted planes, and it distributed pointedly or in the shape of scattered points in sheared basins. The reverse, normal and strike-slip faults had different occurrences, which decided the oblique or vertical conductions of abnormally high pre-ssure. There were different ways for pressure reservation or releasing in compression or reversion. From the dynamic evolution of basin to the dynamic evolution of reservoir and fluid, it was an important step for the application of basin-orogeny coupling theory.
