摘要
为解决渤海油田堵塞问题,通过测量界面张力、洗油效率以及润湿反转等性能优选出性能较好的表面活性剂,通过测量萃取剂的洗油效率优选出性能好的萃取剂。将优选的表面活性剂与萃取剂复配成乳液型洗油剂,测试其配伍性、稳定性以及洗油效率,并分析其洗油机理。研究结果表明,单一表面活性剂对油砂洗油效率最高的是OP-10,为29.4%;较好的萃取剂为石油醚和二甲苯,对油砂的洗油效率可达80%,将表面活性剂与萃取剂进行复配之后,洗油效率可显著提升至95%,所研制的配方为2%二甲苯+8%石油醚+2%OP-10的乳液型洗油剂具有良好的配伍性和稳定性,具有较好的推广应用价值。
In order to solve the problem of plugging in Bohai oilfield,through measuring interfacial tension,washing oil efficiency and wettability reversal properties,the surfactant with better performance was selected,the extractant with good performance was optimized by measuring the oil washing efficiency of extractant.The emulsion type oil wash agent was prepared by combining surfactant and extractant,and the compatibility,stability and wash oil Efficiency was measured and oil washing mechanism were analyzed.The results showed that the single surfactant with the best oil washing efficiency for oil sands was OP-10,being of 29.4%.The better extractants were petroleum ether and xylene,and the oil washing efficiency of the two extractants to the oil sands reached up to 80%.After combining surfactants and extractant,the oil washing efficiency could be significantly increased to 95%.The developed emulsion detergent,composed of 2%xylene,8%petroleum ether and 2%OP-10,had good compatibility,stability,possessing good application prospects.
