摘　　要：研究聚焦于油气储运管道泄漏对地下水污染的深度分析。在污染区沿地下水流向垂直方向设置10个观测井,在10个观测井的不同深度分别采集水样。石油类污染物的水质分析指标包括总油浓度、苯系物、长链烃、氯化钠,天然气污染物的水质分析指标包括溶解氧、硫化物、挥发性有机物,分别采用不同方法实施含量测定。结果表明,油气泄漏严重污染地下水,包气带污染更甚。苯系物与硫化物污染呈扩散态势,以泄漏点为中心向地下水流动方向递减。并强调,油气管道泄漏对地下水环境的污染影响重大,需采取有效措施加以防控,确保环境安全。This study focuses on the in-depth analysis of groundwater pollution caused by oil and gas storage and transportation pipeline leaks.It sets up 10 observation wells vertically along the groundwater flow in the polluted area,and collects water samples at different depths from each of the 10 observation wells.The water quality analysis indicators for petroleum pollutants include total oil concentration,benzene derivatives,long-chain hydrocarbons,and sodium chloride,while the water quality analysis indicators for natural gas pollutants include dissolved oxygen,sulfides,and volatile organic compounds.Different methods are used to determine the content.The results indicate that oil and gas leaks seriously pollute groundwater,and the pollution in the unsaturated zone is even more severe.The pollution of benzene derivatives and sulfides shows a diffusion trend,decreasing towards the direction of groundwater flow from the leakage point.Oil and gas pipeline leaks significantly impact groundwater pollution,requiring effective measures for prevention and control to safeguard environmental safety.
