摘要
新疆地区油气资源非常丰富,但其开发过程对地下水资源造成了一定影响。为明确地下水污染现状,进行了油田开发区域地下水污染现状调查。本文从水质调查监测井的设置情况、水质监测指标、采样方法及采样频率及污染评价方法等方面进行了简要分析。利用一年时间内分三个监测周期对30个监测点共取样9批,每个水样分析21项监测指标,共计5670个水质监测数据。对这些水质监测数据采用单项污染指数法和综合污染指数法,与《地下水质量标准》中相关指标进行对比分析,对各监测点的水质污染情况进行了评价,以此分析油田开发区域地下水资源污染现状。评价结果表明:油气开发活动对地下水资源造成了一定的污染,特别是出现渗漏的干化池周围地下水污染严重。根据评价结果,有针对性地提出了预防措施,对于石油开发过程中制定保护地下水资源的政策具有一定的参考价值。
The oil and gas resources in Xinjiang are very rich.But the exploiting prosess of oil and gas in some district made the groundwater polluted.The survey of pollution on groundwater was conducted to definite the current pollution situation.This paper briefly introduced the condition of surveying well,mo-nitoring indicators ,sampling methods ,sampling frequency and the methods of evaluation.The evaluation of groundwater pollution was conducted by single pollution index evaluation method and comprehensive pollution index evaluation method using collecting data from 30 monitoring points of sampling 9 times through one year ,21 monitoring objectives and 5670 data.The items of evaluation are accordant with the ＂Quality Standard for Groundwater＂.The result of this evaluation showed that the exploiting action for oil and gas caused groundwater pollution ,especially near the drying tank that find some seepage poles.The precaution measures were put forward according to the data of the survey,witch can provide some reference for us to make policies of groundwater resources protection in petroleum development.
