Abstract:

According to the characteristics of the high COD of the waste drilling mud extracts in Shengli Oilfield, the solidification treatment of waste mud was studied by using the composite curing agent composed of cement, fly ash, additive A and additive B. Through orthogonal experiments, the optimum mass fraction proportion of several kinds of chemicals in the treatment of waste drilling mud was found out: cement 10%, fly ash 20%, additive A 3%, additive B 0.5%. The results showed that the COD of the slurry was reduced from 896.84 mg/L to 72.35 mg/L, when the composite curing agent was used.

Key words: waste drilling mud, orthogonal experiment, compound curing agent
