【摘要】 研究了钻井废弃泥浆中铬的形态、活性以及在泥浆池中的迁移转化规律.结果表明.由于土壤对铬的吸附能力强,泥浆可以降低水在土壤内的渗透能力.钻井完井后的废弃泥浆经过适当坑埋处理.其中的铬一般不会对土壤及环境产生较大的污染.更多还原

【Abstract】 The chemical species and migration of total chromium in waste drilling muds were studied. The effects of chromium in waste drilling muds from Shengli Oilfield on soil were determined in laboratory. The results show that soil has a good absorbtivity to chromium. The total chromium of buried waste drilling muds will not result in the pollution for wide-scale area of soil environment around drilling workplace.更多还原
