潜油螺杆泵取消了抽油杆,将驱动装置移至井下,在继承了地面驱动采油螺杆泵优点的同时,也克服了其固有的缺陷。北2-356-84是萨北油田第一口潜油螺杆泵,也是第一口潜油直驱螺杆泵试验井,投产已有8个月。本文从潜油直驱螺杆泵的基本结构入手,与螺杆泵进行对比,分析其在油田的适用性;根据这在生产中出现的问题,归纳了该设备在日常管理中的注意事项;并提出所应做的后续试验。
Submersible screw pump to cancel the sucker rod, the drive moved to the well, inherited the advantages of ground-driven oil recovery screw pump, but also overcome its inherent shortcomings. North 2-356-84 is the first sub-Sarawak oil submersible screw pump, is also the first submersible direct-drive screw pump test wells, put into operation for 8 months. This paper starts with the basic structure of the submersible direct-drive screw pump, compares it with the screw pump, and analyzes its suitability in the oil field. According to the problems in the production, this paper summarizes the precautions of the equipment in the daily management. Follow-up test should be done.
