This article describes the design features of the development and infrastructure development of Novoportovskoye oil and gas condensate field. Unlike traditional reserves for oil and gas condensate fields with a high gas factor, it is often impossible to use a mechanized method of production (ESP, USGN). To solve this issue, the world leaders of the industry are developing special tools and technologies, the introduction of which will solve the emerging challenges. The purpose of the work is the introduction and adaptation of new technologies of oil production in narrow areas of wells. In the present work, a new application of the integrated model for the local determination of the efficiency of gas lift operation is used. The economic model developed by the authors made it possible to identify the main cost items that affect the choice of the method of operation. The experience obtained as a result of the presented work can become the basis for forecasting and better choice of the method of operation.

 

Materials and methods

Thanks to the design method, the existing problem was decomposed into its component parts. By means of mathematical modeling of Petex, OLGA, Pipesim the integrated model of the developed field was constructed and calculated. Using hydrodynamic modeling and statistical-probabilistic method, it was possible to predict the work of the designed objects for a period of 20 years. The digital model made it possible to compare the target method of operation of electric centrifugal pumps with an alternative technology in the form of gas lift operation. In-depth analysis of the Fund and targeted implementation of gas lift wells will provide an additional increase in oil production from 150 to 780 thousand tons from each oil Bush for 20 years.

 

Results

In the present work, a new application of the integrated model for the local determination of the efficiency of gas lift operation is used.

 

Conclusions

Using integrated modeling it was possible to predict the work of the designed objects for a period of 20 years.

The economic model developed by the authors made it possible to identify the main cost items that affect the choice of the method of operation.

The experience obtained as a result of the presented work can become the basis for forecasting and better choice of the method of operation.
