摘要:

电潜往复泵是针对低渗透油藏提出的无杆采油设备,作为高效节能举升新技术之一,应用规模逐年扩大。针对油田生产中存在的问题:创造性地提出一种潜油直线电机的优化方法,包括改善电机举升力和控制方式;为深井或大排量井研制新型双作用减载抽油泵;研发新型铝合金潜油电缆以实现降低一次性投资成本。现场应用90口井,平均检泵周期由452 d提高到693 d,最长检泵周期突破1 037 d,平均节电率达45.6 %。应用效果表明优化升级的新工艺具有更好的可靠性、适应性和经济性,有利于电潜往复泵规模化应用,也为深入研究长线潜油电缆变频系统和电潜往复泵井下工况监测提供依据。

Abstract:

Electric submersible reciprocating pump is a rodless oil extraction device for low-permeability reservoirs. As one of the new technologies of high efficiency and energy saving lifting, its application scale is expanding year by year. In the light of problems of oil field production: we creatively proposed an optimization method for submersible linear motors, including the motor's lifting capacity and control methods; then we developed a new double-acting load shedding pump for deep oil wells or large displacement oil wells; after that we researched and developed new aluminum alloy submersible oil cables to reduce one-time investment costs. It is applied of 90 oil wells, then we found that the average pump inspection period increased from 452 to 693 days, the longest pump inspection period exceeded 1 037 days, and the average electricity saving rate reached 45.6 %. The applications showed that the new optimized and upgraded technology had better reliability, adaptability and economy, which was beneficial to the large-scale application of electric submersible reciprocating pumps. It also provided a basis for in-depth study of variable frequency control of long line submersible oil cables and monitoring of downhole working conditions.

Key words: electric submersible reciprocating pump, submersible linear motor, double-acting load shedding pump, aluminum alloy submersible oil cables, pump inspection period
