Annotation:

Digitalization of gas and gas condensate fields implies a change of the currently used approaches to managing the production of natural gas and gas condensate, which means the emergence of "smart" systems with a high degree of production intellectualization, the use of digital twins and the development of integrated information systems that combine the level of production with the level of enterprise management. At the same time, a significant proportion of typical operations used for the implementation of the assigned monthly technological mode is transferred from manual or automated ones to the category of those ones carried out automatically with periodic acknowledgement of key events by the operational personnel of production companies. Such an approach makes it possible to significantly reduce human participation in the decision-making and implementation chain and, as a result, start practicing the operational management of the field in real time, increasing production efficiency. However, this transition cannot be completed immediately and in full due to the presence of significant risks associated with the inevitable imperfection of the new technology. Debugging of the system should be performed in advance, even before its subjection to pilot tests with the required corrections and the software improvements. In order to solve this problem, the "Field simulator" program stand was developed on the basis of a permanent integrated model (PIM). The stand performs a software simulation of a gas/gas condensate field operation with simulation of physical processes occurring in the system reservoir–wells–gas complex preparation unit–booster compression station network and forms feedback in the form of synthetic telemetry, which allows closing the control cycle and studying all aspects of the system operation in conditions close to the real ones.
