摘要
采用海底油水分离系统不仅能够减轻立管压力、降低举升动力消耗、解决高含水问题,而且能降低井口背压、进而可以提高采收率。目前世界海底油气水分离技术主要有举升分离、常规重力分离、卧式重力分离、静电聚结强化型重力分离、管式分离、气-液旋流分离和超音速气-液分离技术等。在参考大量文献的基础上,重点介绍了这些分离技术原理和设备,以及各种技术设备在海洋石油上的应用实例。根据这些油气水分离技术在各个油田的应用情况,总结出目前海底油气水分离技术存在的问题,并展望其未来的发展趋势,为中国海洋石油的水下生产技术提供支持。
Submarine oil-water separation system not only can reduce stand pipe pressure,lifting power consumption and high water cut,but also reduce wellhead backpressure,hence improving recovery factor.The existing techniques of submarine oil-gas-water separation mainly include lifting separation,conventional gravity separation,horizontal gravity separation,electrostatic coalescence enhanced gravity separation,tube separation,gas-liquid hydrocyclone and supersonic gas-liquid separation.Based on investigation of a great amount of literature references,this paper addresses the principles and equipments of these separation techniques,as well as the application cases of various equipments in offshore oil industry.Based on field applications of these oil-gas-water separation techniques,the problems are summarized and future development trend is prospected,thus providing technical support for China's offshore oil production.
