摘　　要：气田开发对浅层地下水环境的影响主要来自采输气田水 ,主要污染因子为COD、硫化物和氯根(Cl-)。根据工程特点 ,提出了评价气田水对浅层地下水环境影响的一般程序和方法。其要点为 :①根据评价区水环境现状及地质地貌特征确定评价区域边界 ;②根据工程特点判明主要污染源 ;③根据地下水环境现状设计实验室和现场试验方案和项目 ;④选择合理的试验方法确定有关参数 ;⑤选择合适的软件进行模拟预测和环境影响评价。还根据预测结果讨论了上述评价程序和方法的适用范围。The main pollution sources of shallow groundwater are gas-field water in the gas-field exploitation process. The pollutants mainly include COD,sulfides and Cl -. According to the characteristics of the gas-field exploitation,the general procedure and method of environment impact assessment for shallow groundwater are developed. They are summarized as follows:①According to the water environment situation and the features of geology and landform,the boundaries of the evaluated region are determined;②According to the characteristics of the gas-field exploitation,the main pollution sources are verified;③According to the existing situation of the groundwater environment,the experimental scheme and items in laboratory and field are planned;④Reasonable experimental methods are selected to decide relevant parameters;⑤Suitable software is selected to simulate,calculate and assess the environment impact. Finally,the applicable range of the above-mentioned assessment program and method is discussed based on the calculation results.
