螺杆泵是开采高粘度、含固相流体的理想机采方式。针对地面驱螺杆泵的技术局限性 ,开发研制了综合无杆采油技术井下电机驱动和螺杆泵为一体的电潜螺杆泵采油系统。对电潜螺杆泵采油系统的技术特点、开发该系统的技术关键及解决方式、系统组成及工作原理、主要技术指标及选井要求进行了阐述 ,并就所开发出的第一套电潜螺杆泵采油系统的现场应用情况作了介绍。研究及现场应用表明 ,该系统为螺杆泵的应用提供了更广阔的空间。
Screw pump is the exploitation of high viscosity, solid phase fluid containing the ideal machine mining methods. In view of the technical limitations of the ground screw pump, an electric submersible screw pump production system has been developed that integrates the shaftless motor drive and screw pump. The technical characteristics of electric submersible screw pump oil production system, the development of the system’s key technology and solutions, system composition and working principle, the main technical indicators and well selection requirements were described, and developed the first set of electric screw Pumping system on-site application of the situation were introduced. Research and field application show that the system provides a wider space for the application of screw pump.
