摘　　要：为解决建设项目对地下水水质可能造成的直接影响问题,通过对地下水环境影响进行识别,在井场钻井工程建设阶段对地下水环境进行了监测与分析。结果表明:在正常工况下,钻探施工不会对地下水环境造成明显影响;非正常工况下,气井钻探过程中,事故状态下钻井废水渗漏会对地下水水质产生污染,但污染范围相对较小。另外石油类污染预测结果表明,气井在钻探施工事故状态下,钻井废水中的其它污染物,也会在钻孔周围局部范围形成污染晕,只是如石油类一样,范围较小而已。最后,提出有针对性的地下水污染防控措施与对策。To solve the direct impact of the construction project on groundwater quality,the groundwater environmental impact is identified,and the groundwater environment is monitored and analyzed during the construction stage of drilling engineering in well site.The results show that under normal conditions,the drilling construction does not have a significant impact on the groundwater environment.Under abnormal conditions,the leakage of drilling waste water pollutes the groundwater quality in the process of gas well drilling,but the pollution range is relatively small.In addition,the prediction results of petroleum pollution show that other pollutants in drilling waste water will form pollution halo in the local area around the drilling,just like petroleum,the scope is small.At last,the paper puts forward the prevention and control measures and Countermeasures of groundwater pollution.
