| 摘 要： | 分析了１９７５年海城７．３级、１９７６年唐山７．８级以及１９８９年大同６．１级等地震前后胜利油田油井的动态变化特征。研究了油井动态异常变化与地城三要素的关系，地震前油气比的异常幅度比产油量的异常幅度大；异常幅度与震级的大小呈相关，与震中距呈负相关；对于震中距较远的地震，异常多表现为突跳变化；城吉距较近的地震前异常出现早，且形态复杂，基本可分为早期趋势变化、中期震荡变化和震前突跳３个过程，最后对异常

| Abstract: | Anomalous characteristics of dynamic of oil wells in Shengli oil field before the 1975 Haicheng M S7.3 earthquake,the 1976 Tangshan M S7.8 earthquake and the 1989 Datong M S 6.1 earthquake etc. are analysed.Relationships between anomalous changes of dynamic of oil wells and origin time,place and magnitude for a coming earthquake are studied. Anomalous amplitude of ratio between oil and gas is larger than that of oil output of oil wells.The larger the anomalous amplitude,the larger the magnitude of coming earthquake.The shorter the epicentral distance,the larger the anomalous amplitude.The anomalies before earthquakes distant from the oil wells is a shape of sudden jump.The anomalies before earthquakes near by the wells arise more early with a complicated shape,which can be divided into early term trend change,mid term vibrant change and sudden jump before earthquake in the main.Finally,mechanism of the anomalies is discussed. |
