水平井螺杆泵开采技术研究

Research on technology of screw pump recovery in horizontal wells

伴随安塞油田水平井螺杆泵举升工艺的引进，参数优化、杆柱组合、清防蜡、泵况诊断等配套技术的缺乏．给水平井开发、管理带来一定的难度为此，建立一套适应安塞油田的水平井螺杆泵开采配套技术．确保水平井正常生产．为今后水平井的有效开发提供基本依据。

With the application of screw pump lifting technology to horizontal wells in Ansai oilfieht, the lack of supporting technologies, such as parameter optimization, tubing string assemblage, paraffin removal and control, and pump status diagnostic etc., has brought some difficuhies to the field development and management on horizontal wells. To this end, a set of matching technologies that are suitable for screw pump reeove17 technology on horizontal wells in Ansai Oilfield is established to ensure the normal production of horizontal wells, and provide the fundamental basis for further effective development of horizontal wells.
