In the current time, the geological and technological model is the main tool for forecasting the indices of developing hydrocarbon deposits. To ensure the required accuracy of calculations, the updating and adaptation of the model to the historical development data are carried out constantly taking into account the large volumes of incoming data. The purpose of this work is to create and implement algorithms that allow to automate certain tasks of the process of designing and maintaining the development of hydrocarbon deposits. The formed approach provides accumulation, structuring and operational analysis of geological and commercial information that allows to improve the quality of adaptation of the flow model, to increase the accuracy of making managerial decisions during the development of hydrocarbon fi ds and engineering processes.
Materials and methods
On the object-oriented programming language C# with the use of functions and procedures, a program created that implements the author's algorithms for adapting the hydrodynamic model of the gas-condensate field.
Results
An approach has been developed to ensure the accumulation, structuring and operational analysis of geological and development field information, which allows improving the quality of adaptation of the filtration model, increasing the time for solving engineering problems, and increasing the accuracy of management decisions.
Conclusions
Modern approaches to the history matching of the flow model, as the main tool for forecasting and regulating the production of hydrocarbon reserves, impose higher requirements on the development fi d analysis process-it is necessary to evaluate a multitude of factors with a signifies ant amount of information. To solve the problem of analyzing the results of calculation of technological development indicators using flow models, algorithms are implemented that allow to automate the process of engineering evaluation of the history matching and prepare report materials (tables, graphs, illustrations) characterizing its quality. The need to use the developed software product that has access to the network fi d data base is due to a constant increase in the amount of information coming from the fi d at the stage of transition from the exploration stage to the stage of pilot industrial and industrial development. In addition, today there is no flexible software product on the market that is able to accurately cover the specifies of the data of a complex developed filed. Advantages of the presented solution for analyzing results of flow model calculations are: no need to purchase and use additional licenses for software to analyze the results of flow modeling; simple distribution of the program among the employees of the unit and organization of access to a single database of data; the possibility of simultaneous analysis by an unlimited number of users; preparation of regulated reporting materials (graphs and tables). The formed approach provides accumulation, structuring and operational analysis of geological and development find information, which allows improving the quality of history matching of the flow model, increasing the time for solving engineering problems, increasing the accuracy of management decisions during the development of hydrocarbon fi ds and engineering processes.
