摘要
采用OECD推荐的需氧性简易生物降解能力实验——带盖小瓶海水实验法,对7种钻井液添加剂的生物降解性进行了较为详细的研究。研究结果表明,7种钻井液添加剂在所研究的浓度(20mg/L)范围内均能发生生物降解,其降解难易程度与分子结构密切相关,生物可降解性顺序为:淀粉类产品>烯类单体聚合物>
The biodegrability of 7 kinds of mud additives was studied by determining the content of dissolved oxygen in water, a simple biochemical oxygen demand testing method. It is shown that biodegrability of the 7 kind of chemicals tested below 20 mg/L can take place. The sequence of biodegrability from high to low is : starch, polymers of allyl monomers, and additives containing aromatic group.
