| 摘 要： | 盆地的构造演化通过构造活动、沉积体系控制了异常压力的发育,同时异常压力的存在对后期形成的断层有影响.本文通过双元孔隙度演化函数建模对渤南凹陷的古压力进行了恢复,研究表明,渤南凹陷的异常压力主要在裂陷期末开始发育,在坳陷期达到最大.同时由于异常压力的存在引起了流体压裂,对南部缓坡带盆倾断层的形成具有诱导作用.

| Abstract: | The tectonic evolution controls the development of the abnormal pressure through the tectonic activity and sediment system. At the same time, the existence of the abnormal pressure has an important effect on the formation of the later fault. Based on the study of dual porosity function modeling, the paleo-pressure of Bonan Sag is reconstructed. The result shows that, the abnormal pressure of Bonan Sag begins to develop in the end of rift period, and reaches to the maximum at the final period of depression. The existence of the abnormal pressure also results in the hydrofractruring, and it has an inducting function to the formation of the inclined basin faults in the southern ramp region. |
