摘要
在油田开发后期,随着产液量的增加及综合含水率的升高,使得油田集输系统的负荷加大,造成电能和天然气的消耗越来越大。针对这种情况,基于集输系统节能潜力点的分析,以区域性转油站、联合站为重点,进行了系列性节能改造实践。采取的技改措施包括外输泵优化梯次配备、外输变频装置更新及优化运行、加热炉烟道挡板调节技术、加热炉物理除防垢。实施上述措施后,吨液耗电从0.99 kWh/t降至0.97 kWh/t,吨液耗气从0.62 m^3/t降至0.60 m^3/t,大幅提高加热炉燃烧效率,显著降低集输系统的生产成本,确保高含水油田开发的经济性、高效性。
In the later period of oilfield development,with the increase of liquid production and integrated water content,the burden of oilfield gathering and transportation system increases,resulting in the consumption of electricity and natural gas is more and more large.In view of this situation,based on the analysis of energy saving potential points of gathering and transportation system,a series of energy saving transformation practices were carried out with regional transfer stations and combined stations as the key points.The technical improvement measures adopted include optimized cascade equipment of external transport pump,update and optimized operation of external transport frequency conversion device,regulating technology of flue baffle of heating furnace,physical cleaning and anti-scaling of heating furnace.After the actual application of the above measures,the power consumption per ton of liquid decreased from 0.99 kWh/t to 0.97 kWh/t,and the gas consumption per ton of liquid decreased from 0.62 m^3/t to 0.60 m^3/t,which greatly improved the combustion efficiency of the furnace,significantly reduced the production cost of the gathering and transportation system,and ensured the economy and high efficiency of the development of high water cut oil fields.
