联合站系统前端降温后端升温技术探讨

Technical discussion on front-end cooling and back-end heating in multipurpose station

随着低温集输在油田实施的规模和深度逐渐加大,污水进站温度逐渐降低,滤料再生效果变差,影响污水处理效果,水质不能持续稳定达标。针对集输系统降能耗、污水系统保水质日益突出的矛盾,开展前端降温后端升温技术研究。通过建立反冲洗水升温系统,提高反冲洗水温度,摸索合理的反冲洗运行参数,解决低温集输影响水质的瓶颈问题,达到节能、保水质双赢的目的。

With increasing gradually the size and depth of low temperature gathering and transportation process in oilfield and decreasing the inlet temperature of sewage water, the effect of filter material regenerating will become poor, the effect of sewage water treating has been impacted. The sewage water quality can not meet the needed requirements. In order to reduce the energy-consumption of gathering and transportation system and ensure the water quality of sewage water system, the frontend cooling and back- end heating technology has been developed. The water temperature for backwashing can be increased by the heating system for backwashing. The reasonable backwashing operation parameters have been explored, the bottleneck problems for water quality affected by low temperature gathering and transportation process have been solved, the double-win goal of energy-saving & water quality-ensuring has been achieved.
