Treatment of waste oil-based drilling fluid in Jianghan oilfield
摘要
Abstract
The direct discharge of waste oil-based drilling fluid in Jianghan oilfield will certainly lead to serious pollution of ecological environment because it contains much pollutant. According to the characteristics of waste oil-based drilling fluid in Jianghan oilfield, the waste oil — based drilling fluid is treated with chemical demulsification, demulsifier, coagulant and flocculant are to be added into waste oil-based drilling fluid. The results show that the oil recovery rate was 94. 2% , the waste water reached Ⅱ ~ class criteria specified in Integrated Wastewater Discharge StandardCGB 8978 — 1996) after Fenton oxidation treatment, the removal rate of COD was 97. 35% and the removal rate of chroma was 95. 83%. After curing 96 hours, the tightness of cured resin reached Ⅳ — class, the leaching solution of cured resin reached Ⅱ —class criteria specified in Integrated Wastewater Discharge Standard (GB 8978 — 1996), it could realize the hazard-free treatment of waste oil-based drilling fluid in Jianghan oilfield.关键词
