摘　　要： 化学驱油技术是当今油气田开采必备的技术手段之一,随着化学驱油技术的使用,产生了许多的废液。文章综述了在化学驱油技术中使用的表面活性剂、压裂液、石油污染物、聚合物、酸以及碱进入环境后产生的影响,进入土壤,使土壤降解能力下降,甚至出现结块现象;进入大气,会造成酸雨;进入水体,会引发赤潮、水华等水体污染现象。 Chemical flooding technology is one of the necessary technical means for extracting oil and gas. With the use of chemical flooding technology, a lot of waste liquid was produced. The article reviews how the environment was effected by using surfactants, fracturing fluids, petroleum contaminants, polymers, acids, and alkalis in chemical flooding technology. Penetrating into the soil, it could decrease soil degradation capacity, even agglomeration. Going to the atmosphere, it might cause acid rain; flowing into the water, it will lead to red tide, bloom and other water pollution.

关 键 词： 化学驱油技术 环境影响 土壤污染 水体污染 大气污染
