【摘要】 介绍了钻井废弃物中一些主要有害物质的分析测试方法,分析了钻井废弃物中有害物质的评价指标及其生物降解性和生物毒性的评价标准,并对某油田5口井的钻井废弃物（钻井废浆和钻井废水）进行了环境可接收性评价。结果表明,钻井废浆中pH值、COD_Cr和油超标,钻井废水中总铬含量、COD_Cr、色度、pH值、悬浮物和油等超标;钻井废浆和钻井废水的生物毒性都较小或无毒,但其生物降解性都较差,易产生生物富集现象,具有潜在的危害。更多还原

【Abstract】 The paper lists some common test and analysis methods and standards used to evaluate the environmental safety of drilling wastes in China. Evaluation to the drilling wastes from 5 wells shows that such indexes as CODcr, pH value, colority and oil content go beyond the standards. Although the biological toxicity of some wastes is low, the degradability is poor. Some proposals on the disposal of drilling wastes are given.更多还原
