The method of API RP 11L is proposed to design the rod string of pumping steel wire rope in the continuous oil sucker rod extraction system of steel wire rope. The vibration system model and boundary conditions similar to those of sucker rod steel rod are deduced. The design method of steel wire rope In the design procedure of the rope column of oil recovery system, the design parameters are given in detail: the equivalent elastic modulus, equivalent density, equivalent stiffness and natural frequency of the rope column, Parameter, the frequency coefficient table of the rope column of the wire rope production system is given. Based on the methods and data provided in the text, the design of the rope column can be done according to the API RP 11L recommendation
