Breakthrough of carbon fiber continuous sucker rod technology in Shengli Oilfield2017-11-16 14:17:52 1449 views Author：管理员 It is reported that the existence of metal sucker rod history has been more than 100 years, now the Shengli oilfield oil engineering technology research institute of mining machinery experts said, it is time to introduce new materials to replace it.
The existence of such a long time, indeed illustrates the value of metal sucker rod, and difficult to replace, but in the oil field economic and efficient development and low oil prices and other background, the limitations of the metal sucker rod is also more and more significant. For example, it is more important than itself, it is difficult to get deeper; for example, easy corrosion, high energy consumption and so on. Statistics show that if the weight of the rod is reduced by half, the power consumption can be reduced by 20-30%. Therefore, according to the demand of oilfield development status and the requirements of energy saving and consumption reduction, it is a realistic problem to develop new materials with high strength, light weight, corrosion resistance and abrasion resistance to replace metal sucker rod.
The victory of Academy of engineering machine production by researchers from 2014 the project "study on carbon fiber sucker rod" application technology, the research has been completed as raw materials and improve the adaptability evaluation and study of manufacturing and supporting technology, and experiments were done to obtain good results.
The high strength sucker rod made of carbon fiber continuous rod is a new composite material. It has light weight, abrasion resistance and corrosion resistance. The 16 field tests in Dongxin, and wins mining 4 pure beam, Linpan Oil production plant, the cumulative application of carbon carbon fiber rod rod 23372 meters, maximum depth of 1960 meters, the pump hanging depth of 3001 meters, carbon steel / application range than 1.1-3.7, instead of 53.4%-78.7% steel under wells, the success rate of 100% rod load, an average reduction of 50.8%. The longest production time has reached 11 months and continues to be effective.
The continuous rod of carbon fiber can effectively solve the problems of high energy consumption, lower pump depth and serious abrasion of conventional sucker rod pump, and the prospect of industrialization popularization is broad.
