- Abstract
The oil sludge of an oil production plant in Daqing Oilfield cannot meet the requirements for external transportation after on-site treatment. It has the characteristics of high sediment content, small hydrocarbon component content and high viscosity. Therefore, it is very important to conduct a research on the treatment method for this kind of sludge. Through microscopic morphology observation and measurement of the content of each component of the sludge, the reasons for the difficulty of sludge treatment were analyzed. Screening experiments were carried out on 34 kinds of water-soluble demulsifiers. It was found that demulsifier B was more suitable for the dewatering of experimental oil samples, but the dewatering effect of single agent was not ideal. Therefore, a certain proportion of petroleum ether was considered, and the treatment method of mixing petroleum ether in demulsifier were explored. After mixing with petroleum ether, the dewatering effect of demulsifier is significantly improved, and the treated sludge can reach the standard of transportation for external treatment. Finally, by optimizing the demulsifier dosage concentration, petroleum ether blending ratio and dewatering temperature, the best treatment scheme for the dewatering of the experimental sludge was determined to be demulsifier dosage concentration 150 mg/L., petroleum ether mixing ratio 10%, and dewatering temperature 65 C. The research results provide an efficient, economical, environmentally friendly and feasible treatment scheme for the treatment of sludge in an oil production plant of Daqing Oilfield, and also can provide references for other similar projects.
