摘要
油田化学剂的使用贯穿油气勘探和开发的全过程,但目前其对环境产生的影响甚至毒性作用却不甚明晰。为了探究油田化学剂对环境产生的毒性影响,文章参考了大量国内外的生态毒性的评价方法标准,包括以土壤为载体的化学品毒性评价方法、以水为载体的化学品毒性评价方法和以高等动物为载体的化学品毒性评价方法。此外,根据油田化学剂本身的独特性质及对其进行毒性评价的限制因素,通过对比与借鉴,得出在众多毒性评价方法中微生物法是最具潜力的油田化学剂毒性评价方法,并提出几点针对油田化学剂的生态毒性评价的思考,为今后油田化学剂在环境中的毒性评价方法和体系的完善提供参考。
The utilization of chemical agents on oilfield operations is integral throughout the entire process of oil and gas exploration and development.However,the environmental impacts and potential toxic effects of these chemicals remain poorly understood.In order to investigate the toxic effects of oilfield chemicals on the environment,this study refers to a wide range of domestic and international standards for ecological toxicity assessment methods.These methods include evaluations based on soil as a medium,evaluations based on water as a medium,and evaluations based on higher animals as carriers.Furthermore,considering the unique properties of oilfield chemicals and the limitations associated with their toxicity assessment,this study compares and draws insights from various evaluation methods.It concludes that microbial assays represent the most promising approach for assessing the toxicity of oilfield chemicals.Additionally,the study proposes several considerations for the ecological toxicity assessment of oilfield chemicals,aiming to provide guidance for the improvement of evaluation methods and systems for assessing the toxicity of oilfield chemicals in the environment.
