摘要
针对油基钻井液在作业的过程中会产生含油钻屑、含油混浆、含油污泥等含油危废的问题,为了降低含油污泥的污染性,提高处理效率,降低处理成本,对含油污泥的处理工艺进行了研究。试验结果表明:水热法在降低含油污泥的含水率及含油污泥的减量化方面效果较好,但是含油污泥中仍存在少量的矿物油,后续会重点研究含油污泥中矿物油的处理方法。
The problems of oily drilling cuttings,oily mixing and oily sludge in the process of oil-based drilling fluid action are analyzed.In order to reduce the pollution of oily sludge,improve the treatment efficiency and reduce the cost,the treatment process of oily sludge is studied.The results show that the hydrothermal method has a good effect in reducing the moisture content of oily sludge and the reduction of oily sludge,but there is still a small amount of mineral oil in oily sludge,and the treatment methods of mineral oil in oily sludge will be focused on in the future.
