【摘要】 通过分析浅牛 6井 4次突跳异常特征及与日本海 5次地震的关系 ,认为这 4次突跳异常分别属于日本海 5次地震前的“场兆”异常。这 4次异常为板块边缘的构造活动引起井孔所处区域构造应力场发生变化 ,从而引起含水层下部的含油气层中气体上涌所致。更多还原

【Abstract】 By analysing the characteristics of the four times of sudden bound anomalies and the relationship between the anomalies and the five earthquakes in Japan Sea,it is considered that the anomalies are those of"field precursor"before the five earthquakes in Japan Sea.The four times of anomalies are caused by the structural movement of the plate edge,which caused the change of the regional structural stress field in the area where the well lies.This leads to gushing of the gas in the oil bearing stratum under the water bearing rocks.更多还原
