Annotation
Downhole cutting tools are used to repair oil and gas wells as well as to eliminate complicated accidents. However, their acute shortage at oilfield facilities is obvious. The conducted researches have shown that the restoration technology of downhole cutting tools are currently being introduced into production. Besides, there is no information about the layer applied to the damaged area of the cutting element, the optimal mode of operation, as well as the efficiency of the restored tool.
In the considered article, the problems which have found a scientifically grounded decision and possibility of direct introduction of the restored tool in manufacture are solved.
