| Abstract: | In consideration of 3D space well track and the multi stage pumping rod structure in a deviated well,status of forces appliced on the pumping rod is analyzed by using infinitesimal method according to the dynamic principle,thus methods and formulea are established to calculate the friction forces on different positions of pumping rod in a deviated well Calculated result is basically matched with that of actual well conditions |
