【摘要】 清理了多年来胜利油田油井动态地震前兆监测网的观测资料,分析研究了油井动态地震前兆异常的机理和映震规律。油井地震前兆在异常时间和空间分布上具有与地下水异常相似的特征,时间上以短临和临震异常为主,空间分布上以井震距在200～300km的油井为主,在异常幅度和强度上,油井具有异常变化幅度大、强度高和多为正异常的特征。更多还原

【Abstract】 The earthquake precursory anomaly data since 1975 from oil-well observation net in Shengli oil-field were analyzed.The mechanism and rule of data were studied in the paper.Just like underground water,the earthquake precursory anomalies of oil-wells were mainly distributed between 200～300km from epicenter to well,and in the time,the anomalies were mainly arisen within 90 days before the earthquake,and the abnormal scale and intensity of oil-wells were normally large and strong,and mainly were positive abnormality.更多还原
