| 摘 要： | 通过实测压力数据、泥岩声波压实研究、古压力恢复研究。对川西、川中地区异常压力在纵向、横向上的分布特点的分析，认为该区异常压力分布有明显的分区性；同时，依据异常压力的孕育史模型，恢复本地区的上三叠统古压力的形成与演化历史，认为上三叠统过剩压力高峰出现过两次。分别在晚侏罗世末和早第三纪末；最后分析了该区异常压力与油气运聚的关系。 |
| 关 键 词： | 四川盆地 异常压力 声波时差 油气运聚 |

| Abstract: | Based on the study of the test pressure data,the acoustic time and the reconstrction of paleo-formation pressure, through the study of abnormal pressure in the middle and western Sichuan basin,it's shown that the distribution of stratum pressure differs greatly in different zones;the evolution history of paleo-formation pressure has been restored according to the models of the evolution history of pressure,and it shows that there were two high pressure arouse,the first arouse in later Jurassic and the second in erlier Triassic,analyzing the relations between the excessive pressure distribution and the petroleum migration. |
| Keywords: | Sichuan basin abnormal prssure acoustic time petroleum migration |
