摘　　要：辽河油田石油污水回注对深层地下水资源会构成潜在的威胁。根据地面调查、物探、钻探、环境同位素和水文地球化学等多元信息 ,并借助地理信息系统 (GIS) ,开发了石油污水回注适宜性综合评价模型。该评价模型为 6种评价因素的加权叠加模型 ,其评价结果为适宜性等级分区图。评价结果表明 ,污水回注最适宜区域和一般适宜区域为下辽河平原中部凹陷区 ,而不适宜区域和最不适宜区域为凹陷带的两侧边缘地带。The reinjecting produced water technology may result in a great potential threat to the deep groundwater resources in Liaohe Oilfield. According to the multivariate information including geological survey,drilling,geophysical prospecting,environmental isotopes and hydrogeochemistry, a comprehensive assessment model for evaluating the suitability of produced water reinjection technology was developed by means of geographical information system (GIS). This model is a weighted overlay model of six evaluating factors. The finial output of the weighted overlay model is the map for prioritizing the suitable areas for produced water reinjection. The modeling results show that the central areas of the depressed basin in Liaohe Oilfield are more suitable for produced water reinjection, while the fringe areas of the depressed basin with lower priorities are not suitable. The assessment results may provide the basic information as required for the decision making of produced water reinjection and protection of deep groundwater resources.
