【摘要】：本文主要从油田污水的来源、主要成分、危害程度、水质指标、污水处理工艺技术现状等方面入手,通过对吉林油田新木采油厂污水系统及水质现状分析,提出相应的技术对策：着力解决管理上存在的问题,流程上存在的问题,系统瓶颈问题等。取得的成果：一是自筹资金进行流程完善,解决处理系统流程弊端,有效提高水质。二是进行先导性新技术试验,解决影响回注水水质的瓶颈问题。三是以加强管理为保障,充分发挥现有设备最大能力,提高水质。其中的创新点是污水电解盐水杀菌技术应用及絮凝排泥技术应用。该项成果在新木采油厂应用,有效改善回注污水水质,水质改善一方面减轻回注污水对地层的污染,延缓地层压力上升速度,减少欠注井,同时避免因欠注井增加不断更新注水设备设施,满足油田水趋开发需要。另一方面,解决悬浮超标及细菌超标问题,可以有效遏制地面管线、设备的腐蚀、结垢速度。避免因腐蚀更新设备管线,避免因结垢酸洗管线,造成维修、改造工作量的增加。该项目在加强管理、流程完善以及新技术推广所取得的成果,在吉林油田其他各厂污水水质提升方面具有很高的推广价值。
[Abstract]:In this paper, the source, main components, harm degree, water quality index, wastewater treatment process and technology status of oilfield sewage are analyzed, and the wastewater system and water quality status of Xinmu oil production plant in Jilin oilfield are analyzed. Put forward the corresponding technical countermeasures: to solve the management problems, process problems, system bottlenecks and so on. Achievements: first, self-financing to improve the process, solve the system process defects, effectively improve water quality. Second, pilot new technology test is carried out to solve the bottleneck problem affecting the water quality of water injection. Third, strengthen management as a guarantee, give full play to the maximum capacity of existing equipment, improve water quality. The innovation is the application of wastewater electrolytic salt water sterilizing technology and flocculation and sludge discharging technology. This result has been applied in Xinmu Oil production Plant to effectively improve the water quality of the recycled sewage. On the one hand, the improvement of water quality can reduce the pollution of the injected sewage to the formation, delay the rising speed of the formation pressure, and reduce the under-injection wells. At the same time, the water injection equipment and facilities should be continuously updated because of under-injection wells, so as to meet the water trend development needs of oil fields. On the other hand, solving the problem of suspension exceeding standard and bacteria exceeding standard can effectively restrain the corrosion and scaling speed of surface pipeline and equipment. Avoid corrosion to renew the equipment pipeline, avoid scaling acid cleaning pipeline, resulting in maintenance, renovation workload increased. The project is of great value in enhancing the management, improving the process and popularizing the new technology, and improving the water quality of other plants in Jilin Oilfield.
