【摘要】：油田生产中广泛采用的举升方式主要包括有杆泵、电动潜油离心泵、水力活塞泵和螺杆泵等,近年来,国内外正在试验使用电动潜油电机和螺杆泵结合起来的采油系统。本文对常用的有杆泵和地面驱动螺杆泵的举升特点及适用性进行了分析和比较。针对目前油田在斜井、定向井、高含砂等开采过程中不适宜采用有杆泵的情况,在调研分析国内外现有的电潜螺杆泵的类型及适用性的基础上,对电潜螺杆泵的结构、工作原理及举升特点进行了研究,并对螺杆泵采油系统的供、采的协调进行了分析。针对现有电潜螺杆泵需要解决的一些关键技术问题,如泵的低转速高扭矩输入要求、泵的工作轴向力、井下机组高温高压保护、定子橡胶寿命短、排量低及扬程低等进行了分析,提出了相应的解决方法。本文结合现有的螺杆泵采油新技术及配套措施,对电潜螺杆泵采油系统的应用状况进行了探讨,在此基础上建立了完整的电潜螺杆泵采油系统工艺方案优化设计理论,并进行了计算机设计及现场应用的实例分析。分析研究结果对油田的现场生产具有一定的指导意义。
[Abstract]:The lifting methods widely used in oil field production mainly include rod pump, electric submersible centrifugal pump, hydraulic piston pump and screw pump, etc. In recent years, This paper analyzes and compares the lifting characteristics and applicability of the commonly used rod pump and surface driven screw pump, aiming at the current oil field in the inclined well, the oil recovery system is being tested and used at home and abroad, which are combined with electric submersible motor and screw pump, in this paper, the lifting characteristics and applicability of the commonly used rod pump and ground driven screw pump are analyzed and compared. In the process of directional well and high sand bearing, it is not suitable to adopt rod pump. On the basis of investigation and analysis of the types and applicability of the existing electric submersible screw pump at home and abroad, the structure of the electric submersible screw pump is analyzed. The working principle and lifting characteristics are studied, and the supply and production coordination of the screw pump oil production system are analyzed. Some key technical problems need to be solved in the existing electro submersible screw pump, such as the low speed and high torque input requirements of the pump, are analyzed. The axial force of the pump, the high temperature and high pressure protection of the downhole unit, the short life of rubber stator, the low displacement and the low lift are analyzed, and the corresponding solutions are put forward. The application of electrosubmersible screw pump (ECPP) system is discussed. On the basis of this, a complete optimum design theory of ECPP is established. The computer design and field application analysis are also carried out. The analysis and research results are of certain guiding significance to the field production of oil fields.
