钻井液处理剂及体系生物降解性测试和评价

Biodegradability Testing and Evaluation of Drilling Fluid Treatment Agents and Systems

近年来国家环境保护法规的健全及执法力度提高,为防控石油勘探开发过程中对周围环境造成污染,制定出了一系列的相关法律法规,明确规定石油开采过程中产生的废弃物必须处理达标后才能排放,从而给油气田钻井开发过程中使用的添加剂提出了更高的要求。随着环保型钻井液的不断发展,其生物降解性能的评价也越来越受到重视,通过对钻井液处理剂的生物降解性测试和评价,可以分析生物降解性与分子结构之间关系,指导处理剂的分子结构设计和合成,为进一步改进、优化和设计环境友好型的钻井液体系指明方向。

In recent years,the improvement of national environmental protection laws and regulations and the improvement of law enforcement have prevented and controlled the pollution of the surrounding environment in the process of oil exploration and development,and a series of relevant laws and regulations have been formulated,which clearly stipulate that the waste generated in the process of oil exploitation must be treated to meet the standards before being discharged,thus putting forward higher requirements for the additives used in the drilling and development process of oil and gas fields.With the continuous development of environmentally friendly drilling fluids,the evaluation of their biodegradability has also attracted more and more attention,through the biodegradability test and evaluation of drilling fluid treatment agents,the relationship between biodegradability and molecular structure can be analyzed,and the molecular structure design and synthesis of treatment agents can be guided,so as to further improve,optimize and design environmentally friendly drilling fluid systems.
