摘要:

针对深井有杆泵采油中存在如何降低悬点负荷的问题,开展了深井有杆泵减载技术研究,通过分析玻璃钢混
合杆和深抽减载装置的减载原理,结合实例计算对比分析两种减载技术的减载效果,并采用了悬点最大载荷与最小载
荷之差计算扭矩的方法,研究了两种减载技术的节能效果。结果表明:玻璃钢混合杆减载技术能减小悬点最大载荷达
40.6%,深抽减载装置减载技术平均降低悬点最大载荷22.8%,两种减载技术减载效果都比较明显。玻璃钢混合杆具
有一定的节能效果,而认为深抽减载装置具有节能性的观点值得商榷。这将为深井采油中深抽减载方法选择提供一
定的理论指导。

Abstract:

Aiming at reducing polished rod load of sucker-rod pump in oil production of deep well,the research of load reduction
techniques for sucker-rod pump in deep well is carried out,in which the load reduction principles of fiberglass combined rod
and rod load reducer are analyzed. The load reduction effect of these two techniques is analyzed by practical calculation,and
by the difference between maximum and minimum polished rod load in calculating the torque,the energy-saving effect of the
two techniques is also studied. The results show that load reduction technique of fiberglass combined rod can reduce maximum
polished rod load by 40.6%,and the load reduction technique of rod load reducer can reduce maximum polished rod load by
22.8% on average,which means the two techniques have obvious load reduction effect. Fiberglass combined rod has certain
energy-saving effect,the energy-saving effect of rod load reducer is questionable. This paper can provide certain theoretical
guidance for the selection of load reduction methods for oil production in deep well.
