渤海油田氟苯甲酸示踪剂适应性研究

针对目前渤海油田化学示踪剂存在检测精度低、用量大,微量物质示踪剂成本高等问题,研究了一种新型氟苯甲酸示踪剂的适应性,主要在研究了检测方法的基础上,利用四个油田的水样对2-氟苯甲酸、2,6-二氟苯甲酸、2,3,4,5-四氟苯甲酸三种物质的溶解性、配伍性、相互干扰性、耐盐性、热稳定性、静态吸附性等进行评价。评价结果表明,2,3,4,5-四氟苯甲酸的各项性能较好,满足渤海油田现场使用要求。

Research on the adaptability of Fluoro-benzoic Acid Tracer in Bohai Oilfield

According to current problems of tracer application in Bohai oilfield, such as low detection accuracy and huge consumption of traditional chemical tracer, high cost of micro-material tracer, one kind of fluoro-benzoic acid tracer was researched in this paper. For better understanding adaptability of this tracer to Bohai oilfield, on the basis of researching several detection methods, we evaluated solubility, compatibility, detection interference resistance, salt resistance, heat stability, static adsorption of 2 - fluoro-benzoic acid, 2,6-difluoro-benzoic acid, 2,3,4,5-tetrafluoro acid using water samples from four oilfields. It is showed that 2,3,4,5-tetrafluoro acid satisfied application requirements of Bohai oilfield with better capabilities.
