Abstract
This article discusses the mode of operation of the hoist rope. The work of a steel rope in the talus system of drilling rigs is considered, taking into account the main wear factors. Based on the conducted research, it was revealed that the main factor limiting the durability of the hoist rope is cyclically repeated bending stresses in the rope wires. The carried out theoretical calculations and analysis of the working out of the hoisting ropes under identical drilling conditions, but with different rigging of the hoisting systems, show that the transition to a large number of rigging does not give a significantly noticeable increase in the working time of the rope (and in its consumption).The methodic of the training of the hoisting ropes is proposed. It is shown that the regularity of the distribution of the number of rope bending cycles on pulleys and drum allows us to develop recommendations for drillers to limit the maximum lifting height of the talus block, to develop a methodology for optimal working out (by passes) of the talus rope during the well wiring and to make a program for working out the rope based on the fatigue nature of its wear.
