摘　　要：采用管柱动力学的原理和方法建立了可用于大位移水平井生产、作业管柱的设计与校核方法;编制了井下管柱力学分析软件。在大港油田大位移水平井(张海502FH井)现场试验效果表明,该项技术能较为准确地预测管柱起下过程的井口的动态载荷和管柱受力剖面,确定不同的管柱组合在特定的井筒中的最大下入深度,可以用来设计、校核大位移水平井的生产与作业管柱。Using theory of tubing string dynamics, a designing and checking method for production and stimulation string in extended-reach horizontal well is established and software is developed and used in Dagang Oilfield. The test results of an extended-reach horizontal well Zhanghai 502FH of Dagang Oilfield show that this technology can more accurately predict the dynamic loads and stress of tubing string during the process of tubing completion, and can evaluate the maximum depth of different tubing string combinations in a specific wellbore, end can be used to design and evaluate string of production and stimulation in extended-reach horizontal well.
