【摘要】：在当今石油资源开采中,海洋石油的开采在维护国家能源安全和海洋权益方面具有十分重要的意义和利益。在石油勘探开发快速发展的今天,现代石油工业的环境污染受到社会各界的关注。如何更好的解决在石油勘探过程中污水处理,是目前一些石油开发公司面临的重要问题。为了实现油田环保的目的和中国的生态环境保护工作,现代石油企业的发展应加强对重点油田水处理技术的应用与发展,这在解决石油开采安全和可持续开发利用石油具有非常重要的影响。在本文中,结合当前的应用现场实际生产的水处理技术,对油田生产污水处理的原则、流程和技术领域的深入研究和改进,并结合油田自身的水质特性和技术特点,在水质检验、药剂优化、工艺技术以及关键设备效能分析及升级改造等方面提出符合油田发展、满足油田注水开发需要的采出水处理工艺技术,提高油田回注污水水质达标率和采出水处理整体技术水平,对油田的长远发展具有一定的借鉴意义。通过对渤中25-1油田现有采出水处理关键设备进行改造升级,使之与生产现场相适应,最终满足油田的注水水质标准。另外,结合渤中25-1油田发展历程,探讨现有阶段采出水处理技术中的不足,建立一套实现优质注水的水质控制体系,为油田下一步技术改进提供分析依据,指明渤中25-1油田下步工艺技术优化改造方向,对海上其他油田也起到一定的指导和参考作用。
[Abstract]:In the exploitation of petroleum resources nowadays, the exploitation of offshore oil is of great significance and interest in safeguarding national energy security and marine rights and interests.With the rapid development of petroleum exploration and development, the environmental pollution of modern petroleum industry has been concerned by all walks of life.How to better solve the problem of sewage treatment in petroleum exploration is an important problem faced by some oil development companies.In order to realize the purpose of oil field environmental protection and the protection of ecological environment in China, the development of modern petroleum enterprises should strengthen the application and development of key oilfield water treatment technology.It is very important to solve the problem of safe and sustainable exploitation and utilization of oil.In this paper, the principles, processes and technical fields of oilfield wastewater treatment are deeply studied and improved in combination with the current water treatment technology applied in actual production, and the water quality characteristics and technical characteristics of the oilfield itself are also combined.In the aspects of water quality inspection, medicament optimization, process technology, efficiency analysis and upgrading of key equipment, this paper puts forward the production water treatment process technology that conforms to oilfield development and meets the needs of oilfield water injection development.It is of great significance for the long-term development of oil fields to improve the water quality of oilfield return injection sewage and the overall technical level of recovery water treatment.Through upgrading the existing produced water treatment key equipment in Bohai 25-1 oilfield to adapt it to the production site and finally meet the water injection water quality standard of the oilfield.In addition, combined with the development history of Bohai 25-1 oilfield, this paper discusses the shortcomings of the existing stage recovery water treatment technology, establishes a water quality control system to realize high quality water injection, and provides an analytical basis for the next technical improvement of the oilfield.It is pointed out that the direction of technological optimization of the next step in Bohai 25-1 oilfield will also play a guiding and referential role in other offshore oilfields.
