Comparative Study of Application Effect of Load Reducing Technique in Deep Well Production
摘要
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.关键词
