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.
The morphology, activity and migration and transformation of chromium in the mud of the drilling mud were studied.The results show that the mud can reduce the water infiltration capacity in the soil due to the strong adsorption capacity of chromium to the mud. The mud is properly pitted, with chromium generally not causing significant soil and environmental contamination.
