旺11井映震规律的再认识

RERECOGNITION OF EARTHQUAKE-RESPONSE LAW OF WANG NO 11 WELL

  • 摘要: 旺11井在1976年唐山地震及其强余震之前有喷油异常显示。经统计该井喷油对唐山老震区4级以上地震的映震概率为75%;1984年重新射孔后,改封井测压观测,其压力变化异常对唐山老震区4.5级以上地震的映震概率也达到了75%。所观测到的压力逐时值的突跳变化,对于地震预报有相当重要的参考价值。

     

    Abstract: Wang No. 11 well showed oil-evuption anomalies before the 1976 Tangshan earthquake and its strong aftershocks. According to statistics, the earthquake-response probability of oil eruption of the well to the earthquakes with M≥4 occurred in Tangshan old seismic zone was 75%;after the well-hole re-jetting in 1984, pressure of the sealed well was observed. The earthquake-response probability of its pressure variation anomalies to the earthpuakes with M≥4.5 occurred in Tangshan old seismic zone reached 75%. The observed pressure showed hour-value sudden changes, which has a quite important reference value for earthquake prediction.
