Problems in diagnostics and forecasting for the resource of wire ropes in drilling rigs

Abstract

Continuous monitoring of the rig's technical condition is necessary for efficient use of the rig's wire rope resource. A classification of steel ropes used in the industry has been compiled. The characteristics of the pulley-block rope pulley to power drilling rigs are given. The analysis of recommendations for the selection and operation of rope hoists is carried out. The reasons for the occurrence of complex stress-strain states of the rope during its operation are considered. The analysis of methods for calculating the load-bearing capacity of wire rope and determining the fatigue strength is given. Comparative data on the actual standard operating time of wire rope are given. The scientific problem of predicting the residual resource of wire rope is analytically investigated. For operational control of defects in steel ropes, the prospects of using magnetic flaw detection methods are considered. The article draws our attention to the need to implement the following scientific, technical, and technological solutions, such as improving the design of pulley-block system of drilling rigs; accuracy increase of diagnosis of technical condition and forecasting of resource strings; maintenance of wire rope; this will contribute to a more complete use of wire rope in drilling rig.
