【摘要】：本文针对扶余油田注水地面系统现状,分析制约注水泵站效率、注水管网效率提高的关键因素,从而开展课题研究。作者从站内注水系统和站外注水系统两个方面进行阐述。针对站内注水系统,开展PCP节能技术应用实践降低注水泵站泵管压差,开展注水泵叶轮切削与减级这两种低成本节能技术试验,通过优化泵站设计、扩充泵站能力优化其结构,开展注水泵机组运行工况优化技术应用研究优化注水泵机组日常运行和管理,其主要目标就是提升注水泵机组效率,降低站内泵管压差,从而提高泵站效率。针对站外注水系统,面对扶余油田庞大注水管网与数量众多注水单,开展注水管网优化设计研究,建设接力注水泵站,来优化管网结构与格局,开展站外注水井压力控制技术研究与探索,尝试降低无效水循环新课题的推进与研究,切实有效地提升了站外系统效率,为扶余油田注水系统整体效率的提高奠定了坚实的基础。通过对本课题的研究,清晰的认清了扶余油田注水地面系统效率提高的制约因素,形成一套非常系统的理论和认识,积累了一定的实践经验,也发现了一些有待克服的问题。对于如何提高油田注水系统效率,形成了几点认识:一是降低注水泵管泵管压差对提高泵效率至关重要,常规设计泵站要想达到行来规定标准一般来说都较为困难,所以才出现高压变频、PCP技术、叶轮切削与减级等相应技术解决方案;另外站外注水系统压力调控技术研究、降低无效水循环技术研究是扶余油田最近两年提出的技术新思路,在扶余油田还有一定的潜力空间可挖。
[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.
