针对含压裂液原油进入联合站对"五合一"的电脱效果产生很大影响的问题,通过观测电脱水油水分离界面特性,得出电脱温度,利用原油智能脱水试验仪和水分测定仪开展不同压裂液含量下电脱水曲线测试实验,得到了不同时间下电场强度、电流、含水率之间的关系曲线,同时分析了压裂液含量对电脱的影响规律,确定了室内电脱水最佳运行参数,为龙一联站内脱水方案参数的确定提供了可靠的理论基础。

Study on Electric Dehydration Parameters of Crude Oil Emulsion Containing Fracturing Fluid

Crude oil containing fracturing fluid into the joint station has a great impact on the effect of electric dehydration in the “Five-in-One”. In this paper, by observing the oil-water separation interface features of electric dehydration, the temperature of electric dehydration was determined. Test experiments of the curve of electric dehydration of crude oil with different content fracturing fluid were carried out by using intelligent crude oil dehydration test instrument and moisture meter, the relation curves of electric field intensity, current and water cut in different time were obtained, meanwhile, effect of fracturing fluid content on the electric dehydration was analyzed, and the optimum operating parameters of the indoor electric dehydration were determined, which could provide a reliable theoretical basis for determination of the parameters of dewatering scheme in Longyi station.
