过剩压力 meaning in English

excess pressure

Based on the study of the test pressure data , the acoustic time and the reconstrction of paleoformation 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
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?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?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。
