豫01井水位动态趋势下降因素探讨

探讨了河南范县豫０１井水位自１９９６年９月份以来持续下降的原因，对有可能影响该井水位动态的诸多因素逐一进行了对比分析和研究，认为范县豫０１井自１９９６年９月至今的水位下降与中原油田抽水、注水、采油无关；而当地降雨降荷载效应外没有短期渗流反映；山西长治一带降雨量变化与豫０１井的水位变化基本无关；山东梁册县９７井水位动态与豫０１井水位动太县有较好的一致性，表明山东梁山是豫０１井地下水的补级源，指出该井１９９６年９月至今的水位趋势下降主要是１９９７年干旱、降雨量减少，地下水不能充分地补给所致，亦可能与近年来范地区地壳应力活动增强有关。

Discussion on Trend Descending Factors of Water Level Regime of Yu-01 Well

The paper discussed the reasons of the water level descending of Yu 01 well in Fan county of Henan province since 1996.9,compared and analyzed varied factors influence the water level regime of the well.It is suggested that the water level descending of the well is with no relation to the dewatering the water injection and the production of Zhongyuan oil field.There is no short lived vadose response at the place in question.The water level regime of Liangshan 97 well in Shandong is consistent with the water level regime of Yu 01 well,it is showed that Liangshan in Shandong is the alimentation source of Yu 01 well.The water level descending of the well results from the arid climate of 1997,and relates with the crustal stress activity strengthening in Fan county region in the recent years.
