| 摘 要： | 本文利用胜利、大港、华北和辽河油田油井动态观测井的地震前兆异常资料,对1975年以来华北北部地区发生的9次中强地震进行了油井动态观测井映震能力的分析和研究,获得如下主要认识:油井映震能力较强,是一项重要的前兆观测项目;前兆异常在时间上以短临为主,空间上距震中100—300km为映震灵敏区。

| Abstract: | By using the data of precursory anomalies of oil wells in Shengli, Dagang, Huabei and Liaohe oil fields, the capacity to reflect earthquakes for the dynamic variation of oil wells during the nine times moderate and strong earthquakes occurred in the northern part of North China is analysed and studied. The results showed the oil wells have the higher capacity to reflect earthquakes and are an important observational item of precursory anomalies- Its feature is as follows: the short-term and impending anomalies are main anomalies in time. The sensitive area for reflecting earthquakes is 100 to 300 km from the epicenter. |
