BIPTVAS-Ⅱ型轴向涡流分离器工程样机及其在流花11-1油田的现场试验

摘要

This paper described the structure and operating principle of a BIPTVAS-Ⅱvoraxial separator prototype which was developed with independent intellectual property.The orthogonal experiment,indi-vidual parameter-effect experiment and continuous running experiment that were conducted in LH 11-1 oil-field were analyzed.The experimental results show that,the drum rotation velocity was the key operation parameter affecting the separation performance and only when it rotated at the range of 1650~1700 r/min, could the prototype operate smoothly and effectively.When the inlet oil content was around 200mg/L, even without any addition of chemicals,the BIPTVAS-Ⅱ would run with optimum performance and the outlet oil content could be controlled below 30mg/L.This separation efficiency was higher than that obtained with the hydrocyclone used in LH 11-1 oilfield.The successful development of the prototype will provide the offshore oil industry with a practicable solution for increasing production and decreasing pollu-tion,being worthy of larger-scale application research.%介绍了自主研制的BIPTVAS-Ⅱ型轴向涡流分离器工程样机的结构和工作原理,并对其在南海流花11-1油田成功进行的正交、单一变量和连续运行现场应用试验进行了分析.试验结果表明,转鼓转速是影响其分离性能的最关键操作工艺参数,稳定、高效运行时的转速范围为1 650~1 700 r/min;在不添加任何药剂的情况下,设备以最优操作参数稳定运行,当入口污水含油量在200 mg/L左右时,分离器水出口的含油量可降低到30 mg/L以下,除油效果超过现场安装的水力旋流器.该技术的成功研发将为我国海洋石油工业的增产减污提供可行的技术解决方案,值得进一步开展工程放大应用研究.
