水平井有杆泵深抽工艺的设计与评价

Design and appraisal of horizontal wells deep well lifting technology

  • 摘要: 有杆泵是当前工艺最成熟、应用最广泛的举升方式之一,在水平井中的应用规模也相当大。针对大庆外围深层低渗透油田水平井的特殊条件,介绍了包括差动式举升、新型大斜度抽油泵举升在内的几种新的有杆泵深抽工艺设计方案,并对新型大斜度泵设计和抽油杆扶正等关键技术进行了较详细说明。室内试验和现场应用表明,差动式举升和新型大斜度泵举升工艺具有泵效高、安全性强等特点,能够满足大庆外围油田水平井深抽的要求,并取得了很好的应用效果。

     

    Abstract: Sucker rod lift is one of the most popular artificial lift methods in oil industry. Currently, it has been widely applied in vertical wells as well as in horizontal wells. This paper presents several new types of sucker rod lifting technology for deep horizontal wells in low permeability reservoir, which include differential sucker rod pump and pump lifting technique for highly deviated wells. And the key techniques, such as the pump design in highly deviated well and the centralization of sucker rod, are introduced in detail. Indoor experiments and field application indicated that the differential sucker rod pumping and the new type of pumping technology in highly deviated wells had the characteristics of high pump efficiency and good reliability, which could meet the pumping requirements in deep horizontal wells in Daqing peripheral oilfield.
