The energy and its entire related infrastructure are the main drivers for a economic development and for ensuring a good level of employment. As part of a global study about international energy sector, we evaluate here the impact of technological changes on the state of the energy infrastructure. This study includes a detailed analysis of the global challenges facing the energy industry. We propose scenarios for the development of a modernized energy infrastructure with an assessment of the entire energy system. Our evaluation indicators are chosen in terms of the reliability of the energy infrastructure, of its quality, of the accidents that may happen and of the consequent environmental risks. This study is particularly adapted for forecasting the necessary measures (of technical nature, of governance kind) that have to be implemented to reduce the acceleration of the infrastructure deterioration rate. Our results reveal that the use of digital and information technologies has many positive impacts on the development and on the control of an efficient consumption of energy. In addition, our predictions, due to the further modernization of the energy sector, can contribute and help in the creation of preconditions that will be highly stimulating and profitable to the growth of investments in the energy infrastructure.

The maintenance of oil pumps is a complex task for any operating organization, and for an industrial enterprise in the oil and gas sector of the economy, this issue has a high degree of urgency. One of the reasons for this is a wide spread of pumping equipment in all areas of oil and gas enterprises. At the same time, an aggressive environment, uneven load, remote facilities, and harsh climatic zones (especially in the areas of the Arctic region or production platforms) are factors that make it relevant to develop special systems that help or simplify the maintenance of pumping equipment. Dynamic modeling is one of the modern technologies which allows for solving the urgent issue of assessing the technical condition of equipment. It is the basis of systems that carry out diagnostics and prognostic calculations and allow for assessing the dynamic state of objects under various conditions of their operation, among other functions. Augmented reality technology is a technology that allows for reducing the time for equipment maintenance by reducing the time for searching and processing various information required in the maintenance process. This paper presents an investigation of the effectiveness of an augmented reality and a dynamic simulation system collaboration in oil pump maintenance. Since there is insufficient research on the joint application of these two technologies, the urgent issue is to prove the effectiveness of such collaboration. For this purpose, this paper provides a description of the system structure, gives a description of the development process of the augmented reality system application and tests the application using Microsoft HoloLens 2.

Представлены результаты экспериментов по влиянию энергии удара на интенсивность ударно-абразивного изнашивания модельного инструмента из трех марок инструментальных сталей вида конической пики при ударном взаимодействии с фрагментом гранита. Часть инструмента подвергалась типовой термической обработке, практикуемой на заводах-изготовителях пик, другая — дополнительной обработке холодом или криогенной обработке. Для обоснования возможности переноса экспериментальных данных на натурные условия устанавливались рабочие параметры эксперимента, при соблюдении которых его условия будут подобны условиям работы пики гидромолота. Для выполнения указанного подобия уровень контактных напряжений между модельным инструментом и породой в экспериментах был таким же, как и при ударном внедрении пики. Установлена зависимость между интенсивностью ударно-абразивного изнашивания и энергией удара модельного инструмента, на основании которой рассчитаны интенсивности изнашивания пики гидромолота JCB HM380 при разрушении гранитных фрагментов. Оценивалась наработка пики, за которую принималось количество нанесенных ей ударов до полного изнашивания острия. Из сравнения наработки пик, изготовленных из анализируемых сталей и подвергнутых указанным видам термической обработки, сделан вывод о целесообразности внедрения операций обработки холодом и криогенной обработки в технологический процесс изготовления пик гидромолотов.
