Research On Flexible Continuous Sucker Rod Pumping Technology

Pumping rod is the key component of the rod pumping system. And flexible sucker rod pumping system is a new technology of oil industry in our country recently. The flexible sucker rod has the advantages of flexibility, continuity, light weight and high strength. It can also solve some problems difficult to overcome, such as: thread off, long work time, large friction resistance, and so on. So the flexible sucker rod pumping system exerts a significant influence on productivity and output of oil extraction. But at present, because of the lack of perfect theory for guiding the application of the flexible sucker rod pumping rod as well as its matching equipments and tools, it can not be widely used.Based on the previous theoretical study, the basic theory of feature , force of the flexible sucker rod pumping rod are described. The article analyzes the optimization program of the flexible sucker rod pumping and heavy weight of the flexible sucker rod pumping system. Then it proposes the design of the flexible sucker rod pumping rod. In order to enhance rod pumping efficiency of the system, by doing experiments the article analysis the overstroke of pumping that used flexible continuous sucker rod and the optimal Parameters that can be to attain Maximum liquid production. At the end the matching equipments and tools of the flexible sucker rod pumping are discussed. So the words have positive guidance to use the flexible sucker rod pumping rod. It will also widen application scope and full embody advantages of the wire rope pumping rod.
