Dynamic modeling, development of «digital twins» and software
Simulator program “digital twin” of oil and gas objects operational modes complex (it can also be used as a training simulator for employees working at the facility).
The simulator program developed by the specialists of the centre is intended to simulate the stationary modes operation of compression, drying and low temperature separation of petroleum and natural gases.
Changes in external and internal working conditions are taken into account, including various modes of equipment operation, gas composition.
The program allows to simulate the operation of the object for design, current and prospective modes in different seasons. The software product includes mathematical models of system elements complex in digital form (compressors, turbo-expander units, heat exchangers, separators, control valves, dryers, pipelines), combined into a single digital object – digital twin.
Software product for the selection of compressor equipment (including the drive unit) during the compressor stations design process.
A software product that can be used to select compressors during the design of new compressor stations and existing stations repackaging. The development contains a comprehensive description and compressors and their drives operation principle used in the oil and gas industry, and currently contains more than 2700 operating compressor units. The selecting method of compressor units and gas pumping units is based on the station reliable performance calculation and the life cycle cost. The program is applicable in the preparation of justifications for the compressor units choice in the oil and gas industry and in general industrial facilities. The first version of the software product was developed according to the technical task and with the participation of experts from the PAO “Gazprom neft”.
The program approbation was carried out within the framework of existing industrial facilities. Program versions algorithms are regularly changed for improvement.
Pneumosystem
Enterprises pneumatic networks calculation and optimization program.
The program contains a pneumatic system topology compiling module, a pneumatic network mathematical model based on hydrodynamic resistance calculations according to Darcy-Weisbach, as well as Blasius and Nikuradze empirical formulas and Idelchyk loss factors are used. The mathematical model is verified on real objects and contains correction factors that take into account the depreciation of pipelines.
In addition to these software packages, the following programs have been developed by the specialists of the scientific and engineering group:
- A program for importing geometric parameters of the impeller blade of a centrifugal compressor into CAD BLADETMPORT-1.0;
- A program for the variant gas dynamic calculation of a back-guiding device with blades of variable thickness for a centrifugal compressor RCHVAR-1.1;
- The program of the variant gas dynamic calculation of the blade diffuser of a centrifugal compressor VDCOMR-3.1;
