含油钻屑中包含大量石油类、有机物等有害物质,不经过处理排放,会对环境造成严重污染。目前使用的含油钻屑处理技术主要包括热解析法、焚烧法、微生物代谢降解法等,但是,这些方法均存在不足,不能够快速、高效解决含油钻屑处理问题。本文提出了一种高效、低成本处理含油钻屑的方法,合成了一种含油钻屑清洗剂,采用超声辅助清洗的新技术处理含油钻屑,有效减少了清洗剂的用量,强化了清洗剂的清洗作用。在本文中,考察了清洗剂加量、加热温度和超声时间对除油效率的影响。当55℃的加热条件下,超声10 min,清洗剂加量为7.5 g/L时处理含油钻屑,油的回收率可达95%以上,处理后的钻屑含油量小于1%,剩下的含有清洗剂的废水,可以重复利用,继续作为清洗液清洗含油钻屑。这一技术提高了含油钻屑处理效率,大大降低了处理成本,极具推广价值。 Oil-bearing cuttings contain a large amount of harmful substances such as petroleum and organic matter, which will cause serious pollution to the environment if they are not treated and discharged. At present, the oil-bearing drill cuttings processing technologies mainly include thermal analysis, incineration, microbial metabolic degradation, etc. However, these methods are inadequate and can not solve the problem of oil-bearing cuttings quickly and efficiently. This paper presents an efficient and low-cost method of processing oil-bearing cuttings. An oil-bearing cuttings cleaning agent is synthesized. Oil-borne cuttings are treated with ultrasonic-assisted cleaning of new technologies to reduce the amount of cleaning agent. The cleaning agent Cleaning effect. In this paper, the effect of detergent dosage, heating temperature and ultrasonic time on oil removal efficiency was investigated. When heated at 55 ℃ for 10 min and the detergent dosage is 7.5 g / L, the oil recovery rate can reach more than 95%, the treated oil content is less than 1%, and the remaining Of the waste water containing cleaning agent, can be reused, continue to clean oil-bearing cuttings as a cleaning fluid. This technology improves the efficiency of oil cuttings processing, greatly reducing the processing costs, great promotional value.
