乐安油田是通过蒸汽吞吐减轻原油粘度进行开采的稠油油田。针对其特点,借鉴美国、加拿大污水回用的成功经验和先进技术,建成投产了国内第一座也是最大的一座油井采出水回用于湿蒸汽发生器的大型泵站 ── 乐安污水深度处理站。文章详细介绍了污水深度处理系统以及运行2年来所取得的成果,证明油田采出水深度处理后回用于湿蒸汽发生器技术是完全可行并易于操作的。 Lean Oilfield is a heavy oil field that is exploited by steam stimulation to reduce the viscosity of crude oil. According to its characteristics, learn from the successful experience and advanced technology of wastewater reuse in the United States and Canada, built and put into operation the first and largest oil well in China to recover the large-scale pumping station for wet steam generator, namely Le’an Sewage Depth Treatment station. The article details the advanced wastewater treatment system and the results achieved during the two years of operation. It proves that it is feasible and easy to operate when the treated water is returned to the wet steam generator after deep treatment.
