为解决目前水驱采出液普遍含聚后,联合站一段放水含油超标的问题,开展高效三相分离技术研究。通过对三相分离器进液口、填料装置及捕雾器等结构进行优化,设计了新型三相分离器,利用采出液初步分离、分离聚结、加速沉降、油水收集等技术,实现了含聚原油的高效脱水及脱气,并在转油放水站改造项目中,进行现场应用及效果分析,脱水后污水含油及油中含水均达到了指标要求,从源头上有效地解决了放水站油水分离困难、污水含油超标等问题,同时降低了放水站破乳药剂的用量,降低了生产成本,具有很大的经济效益和社会效益。
In order to solve the problem that the current water flooding production fluid is generally polycondensated, the joint station has a problem of excessive oil discharge and carries out high-efficiency three-phase separation technology. By optimizing the structure of the three-phase separator inlet, packing and mist catcher, a new type of three-phase separator was designed. The technology of primary separation, separation and coalescence, accelerated sedimentation and oil-water collection was adopted to achieve Including the efficient dewatering and degassing of poly-crude oil, and field application and effect analysis in the conversion project of oil-transferring and water-discharging station. After the dehydration, the oil content in the sewage and the oil in the oil meet the index requirements, effectively solving the problems of the drainage station Oil-water separation difficulties, excessive oil and sewage problems, while reducing the dosage of water demulsifier, reducing production costs, with great economic and social benefits.
