【摘要】：本文針對扶余油田注水地面系統現狀,分析制約注水泵站效率、注水管網效率提高的關鍵因素,從而開展課題研究。作者從站內注水系統和站外注水系統兩個方面進行闡述。針對站內注水系統,開展PCP節(jié)能技術應用實踐降低注水泵站泵管壓差,開展注水泵葉輪切削與減級這兩種低成本節(jié)能技術試驗,通過優(yōu)化泵站設計、擴充泵站能力優(yōu)化其結構,開展注水泵機組運行工況優(yōu)化技術應用研究優(yōu)化注水泵機組日常運行和管理,其主要目標就是提升注水泵機組效率,降低站內泵管壓差,從而提高泵站效率。針對站外注水系統,面對扶余油田龐大注水管網與數量眾多注水單,開展注水管網優(yōu)化設計研究,建設接力注水泵站,來優(yōu)化管網結構與格局,開展站外注水井壓力控制技術研究與探索,嘗試降低無效水循環(huán)新課題的推進與研究,切實有效地提升了站外系統效率,為扶余油田注水系統整體效率的提高奠定了堅實的基礎。通過對本課題的研究,清晰的認清了扶余油田注水地面系統效率提高的制約因素,形成一套非常系統的理論和認識,積累了一定的實踐經驗,也發(fā)現了一些有待克服的問題。對于如何提高油田注水系統效率,形成了幾點認識:一是降低注水泵管泵管壓差對提高泵效率至關重要,常規(guī)設計泵站要想達到行來規(guī)定標準一般來說都較為困難,所以才出現高壓變頻、PCP技術、葉輪切削與減級等相應技術解決方案;另外站外注水系統壓力調控技術研究、降低無效水循環(huán)技術研究是扶余油田最近兩年提出的技術新思路,在扶余油田還有一定的潛力空間可挖。
[Abstract]:According to the current situation of water injection surface system in Fuyu Oilfield, this paper analyzes the key factors that restrict the efficiency of water injection pump station and increase the efficiency of water injection pipe network. The author expatiates on the water injection system inside the station and the water injection system outside the station. Aiming at the water injection system inside the station, the application of PCP energy saving technology to reduce the pressure difference of pump pipe in the water injection pump station is carried out. Two low cost and energy saving technologies, cutting and subgrading of impeller of water injection pump, are carried out. By optimizing the design of pump station, the capacity of pump station is expanded to optimize its structure. Research on the Application of optimal operating conditions of Water injection pump Unit the main goal of optimizing the daily operation and management of water injection pump unit is to improve the efficiency of water injection pump unit and reduce the pressure difference of pump pipe in the station. In order to improve the efficiency of the pumping station, in view of the water injection system outside the station, facing the huge water injection pipe network and numerous water injection orders in Fuyu Oilfield, the optimization design research of the water injection network and the construction of the relay water injection pump station are carried out to optimize the structure and pattern of the pipe network. The research and exploration of pressure control technology for water injection wells outside the station is carried out to try to reduce the advance and study of the new subject of ineffective water circulation, which effectively improves the efficiency of the system outside the station. It lays a solid foundation for the improvement of the overall efficiency of water injection system in Fuyu Oilfield. Through the research of this subject, it clearly recognizes the restricting factors of improving the efficiency of water injection surface system in Fuyu Oilfield, and forms a set of very systematic theory and understanding. Some practical experiences have been accumulated and some problems to be overcome have been found. Several understandings have been formed on how to improve the efficiency of water injection system in oilfield. First, it is very important to reduce the pressure difference between water injection pump pipe and pump tube to improve pump efficiency. In general, it is difficult for conventional design pump stations to meet the requirements of operation standards, so the corresponding technical solutions, such as high voltage frequency conversion PCP, impeller cutting and subgrading, and so on, have emerged. In addition, the research on pressure regulation technology of water injection system outside the station, The research of reducing ineffective water circulation technology is a new technical idea put forward by Fuyu Oilfield in the last two years, and there is still some potential space for digging in Fuyu Oilfield.
