On the question of determination of reliability of some elements of drill string in the process of deepening of the well

摘要

The possibilities of application of physical and mathematical methods of modeling of work processes during the deepening of the drill holes as the layer - drill string system, leading parameters of application of probability bounds and characteristics of elements of the system are considered in the article. Methodological issues of forecasting of changes of parameters and their connection with drill string on the certain results of drilling of wells are analyzed.
