【摘要】 经过多年水位观测,发现盘锦地区水位有时出现无震时"异常"变化。将辽河油田石油开采数据与本地区水位资料对比分析,结果表明:盘锦地区地下水位受油田开采影响,抽水、注水影响本区观测井水位趋势变化。为今后研究本区水位中、长趋势变化提供借鉴,为准确识别地震异常提供参考意见。更多还原

【Abstract】 The well of water level observation in Panjin is located in the Liaohe oil field.Through years of water level observation,We found that there are some abnormal changes of the water level data while no earthquake occurred.The author analyzed the relation between the underground water level in Panjin and Liaohe oilfield exploitation.Preliminary results show that:the underground water level is affected by the exploitation of Liaohe oil field,particularly pumping and affusion during mining process affecting the water level trends.The author tried to provide advice about studying the trend changes of water level in future and accurately identify the abnormal change prior to earthquake.更多还原
