摘　　要：分析了 1 999年 1 1月 2 9日岫岩MS5 .6地震前 ,辽河油田 6口观测井的前兆异常特征 .观测项目有水位、采液量、采气量及套管压力等 .该次地震前 6口井的观测资料均出现明显的趋势异常和短临前兆异常 ,辐且具有较好的同步性 ,异常形态表现为升 降 升型 .抽水、注水、气压、温度等干扰因素对观测资料没有影响 。Anomalous characteristics of observation data of 6 wells in Liaohe oil field before the Xiuyan M S5.6 earthquake, Liaoning on Nov.29,1999 are analysed. Observed items are groundwater level, oil recovery volume, casing pressure and gas recovery volume. Trend, short term and impending anomalies appeared in observation data of the 6 wells before the event with fairly good synchronism and a shape of rise fall rise. The test shows disturbance factors, such as water flooding,pumping water,atmospheric pressure and temperature etc. have not influence on the observation data, therefore,the anomalies can be believed.
