The article examines the dynamic features of rigging operations accompanying the processes of arranging exploration wells. The effects of such key factors as the weight of the load, the stiffness of the cable and the lifting speed on the fluctuations of the system are considered. Dangerous modes of rigging operations are also considered. These are system operating modes in which resonant vibrations, excessive dynamic loads, or loss of load stability are observed, which can lead to an emergency or equipment failure. The purpose of the study is to analyze and model the oscillatory dynamics of rigging operations during the development of exploration wells in order to increase their reliability and safety. Special attention is paid to the analysis of vibrations occurring in the “load- rope - lifting device” system due to the inertial, elastic and damping characteristics of the elements. A mathematical model is constructed that describes the free vibrations of a load during movement using rope and winch systems. Based on a system of differential equations, the dynamics of cargo movement under the action of a restoring force and a drag force proportional to speed are described. The calculation results are presented in the form of graphs of displacements, velocities, and accelerations, demonstrating the influence of key factors on the stability and amplitude of vibrations. Based on calculations and graphs, it is established that the load coordinate changes sinusoidally, reaching maximum and minimum values. Engineering recommendations are proposed to reduce vibration levels and ensure safe operation of rigging systems, including the selection of optimal speed modes, the use of dampers and the correct adjustment of lifting parameters. The results obtained can be used in the design and operation of wells, as well as for educational purposes in the training of specialists in the oil and gas industry.
