Annotation:
The authors of the article study the problems of incidents increase due to the loss of drilling tools tightness. The results of a review analysis are presented and the main causes of incidents associated with drilling pipes leakage when drilling wells in the West Siberian region are highlighted. The importance of using nonlinear hypotheses to evaluate the drill pipes degradation process is emphasized. As a result of the scientific and technical analysis, a hypothesis of fatigue damage accumulation was proposed. Modern drill pipes operating conditions require a new approach to predicting the time-period of their failure-free operation.
