“DIAGNOSTICS AND MODERN INFORMATIONAL TECHNOLOGIES IN TECHNOLOGY AND SOCIOMA”

Major scientific achievements:

 

  • the theoretical foundations of the vibration diagnostics of electropump pumps (UEVN) installations and the methodological fundamentals of diagnostics of deep-well sucker rod assemblies (GNSS) for oil extraction, as well as the methodological fundamentals of vibration diagnostics of the drill string (BC), on the basis of which diagnostic models of EVN, GNSU and BC, allowing to predict the development of defects, classify them, determine the direction of their development and the relationship with other defects;
  • methods of bench diagnostics of the UEVN nodes – the submersible electric motor and the centrifugal pump, including the norms of their vibration level, which form the basis of regulatory documents, as well as the technical means for their implementation have been created; the method of selective collection of UEVN nodes, as well as methods and technical means of diagnosing and predicting UEVN, GNSU and rock cutting tools during operation; Traditional methods of diagnosing GNSS have been improved – methods and microprocessor systems for automatic recognition of dynamograms based on Walsh transform and automatic diagnostics of GNSU based on wavelet transform have been developed, the static diagnostic model of the pumping unit has been improved and a dynamic diagnostic model has been developed; developed an elastic coupling PM-180, designed to protect the elements of BC from the dynamic loads that occur during the drilling of roller cone bits; methods and microprocessor-based means of controlling the technical condition were developed: gas pumping units with piping, centrifugal pumping units for reservoir pressure maintenance systems, casting cars of political lines and working bodies of vertical roll mills;
  • а new scientific direction has been developed – mathematical methods for monitoring the VAT of oil and gas facilities based on known movements of a certain set of points on their surface, taking into account the existing force factors and the complex three-dimensional nature of the deformation process, on the basis of which: a computational method has been proposed for the operational control of the VAT of open sections of trunk pipelines (MT ), as well as the method and microprocessor device to control the configuration of the shape of the cross section of the pipe MT; VAT assessment method for the walls of vertical steel cylindrical tanks and their control system based on a laser scanner for contactless measurement of the coordinates of surface points of the tank wall;
  • proposed methods and fundamental solutions to expand the functionality of displacement control devices (PEP) for distributed information-measuring complexes based on contactless phase-code transducers, developed and experimentally studied methods for improving the noise immunity of PFC spectral-phase signals;
  • investigated the relationship between changes in the characteristics of acoustic processes in the process pipeline environment from the place of unauthorized access, insert dimensions and number of inserts, developed a method to control unauthorized access to the process pipeline using excited oscillations generated based on the use of noise-resistant codes, and created a microprocessor system for leak localization;
  • the beginning of the methodological foundations of the construction and study of the operating modes of complex distributed WEB-oriented control systems and diagnostics, within which the following has been developed: a system for monitoring the level of petroleum products in reservoir parks; automated information-measuring system for monitoring the level and forecasting of flood waters; a system for remote monitoring and forecasting the level and concentration of brines in the Dombrovsky open pit and salinization of the Kola industrial region; automated water management system, in particular remote monitoring of home meter displays; proposed the structure of WEB-oriented Smart Grid control systems for distributed energy facilities and others;
  • started conceptual foundations and methodology for designing adaptive complexes Distance learning for technical students, within which the development and introduction of an adaptive system for diagnosing students’ knowledge level into the educational process has begun.
