油田开发项目中大气环境影响预测方法研究

针对油田开发过程中大气污染源点多面广的特点，选用适当的大气环境预测方法已成为问题关键，使用网格处理，分别计算点源（高斯模式）和面源（Ｈ－Ｇ模式）的污染贡献量，得到预测结果，并佐以百色油田的应用实例，得出：多源扩散模式（Ｈ－Ｇ模式）可以反映油田开发多源污染的叠加效果；Ｈ－Ｇ模式计算简便，要求参数少且容易获得，与复杂模式的计算结果相一致，能满足油田开发项目大气环境影响评价的要求。

Prediction method research on the influence of oil field developing projects upon the air environment

Because of the multi-source and extensive air pollution characteristics during oil field developing process,how to chose proper air environment prediction methods has become the key to solve pollution problem.The prediction product was obtained by means of gridding process that calculated the pollution contributions of point sources(Gauss Mode)and surface sources (H-G mode) respectively.It is derived,in addition to the prediction case in Baise Oilfield,that multisource diffusing mode (H-G mode) may reflected the stacked influence of multi-pollution sources during oil field developing process,and the H-G mode,which needed less parameters that was easier to be obtained,was simpler to be calculated.Compared with other complicated calculating methods,H-G mode had derived similar products that may satisfy the requirement of evaluating the influence of oil field developing projects upon air environment.
